How Many Songs Last 1 Hour: Exploring the Rarity and Rationale Behind Extended Musical Pieces
Understanding the Unconventional: How Many Songs Last 1 Hour?
It’s a question that might pop into your head during a particularly long, immersive listening session, or perhaps while browsing through eclectic music genres: how many songs last 1 hour? The straightforward answer is, overwhelmingly, very few. In the vast ocean of recorded music, a song clocking in at a full 60 minutes is an anomaly, a rare gem that breaks from the standard song structure and duration that dominates popular music and most commercial releases. While the average pop song typically hovers around the 3 to 5-minute mark, and even longer pieces in rock or classical genres might extend to 10, 15, or even 20 minutes, a song reaching the hour-long threshold is something else entirely. It’s a significant commitment, both for the artist to create and for the listener to experience.
My own journey into this niche started unexpectedly. I was exploring some experimental electronic music, something I’d dabbled in before, and stumbled upon a track that was listed as 58 minutes long. Intrigued, I hit play. What followed wasn’t just a song; it was an odyssey. It shifted moods, textures, and even implied narratives over its substantial runtime. This experience sparked my curiosity: were there others like it? And why would an artist choose to create something so lengthy when the prevailing industry standard favors brevity?
The reality is, if you’re thinking in terms of mainstream radio play or your typical Spotify playlist, the number of songs that are precisely one hour long, or even close to it, is exceedingly small. We’re not talking about hundreds or thousands of such tracks readily available. Instead, you’re likely looking at a few hundred, perhaps a few thousand, if you dig deep into certain specialized genres and independent artists worldwide. The vast majority of music consumed daily falls far, far short of this duration.
The Standard Song Structure: A Quest for Brevity
To truly appreciate why hour-long songs are so rare, we need to understand the dominant paradigms of music creation and consumption. For decades, the music industry has been geared towards what’s commercially viable. This often translates to songs that are digestible, memorable, and fit neatly into radio formats, playlists, and even the attention spans of a broad audience. The typical song structure, often referred to as the verse-chorus form, is a testament to this efficiency. It provides a familiar, predictable pattern that allows listeners to engage quickly and retain the melody and lyrical themes.
A typical pop song, for instance, might consist of:
- Intro: A brief musical passage to set the mood.
- Verse 1: Introduces the narrative or theme.
- Chorus: The catchy, memorable part that often repeats.
- Verse 2: Develops the narrative further.
- Chorus: Reinforces the main idea.
- Bridge: Offers a change in melody, harmony, or lyrical perspective.
- Chorus: A final, often more emphatic repetition.
- Outro: A concluding musical passage, fading out or ending abruptly.
This structure, while effective, is inherently designed for conciseness. Each section serves a purpose without overstaying its welcome. Extending this structure to an hour would require significant innovation or a complete departure from its core principles. The need for repetition to keep a listener engaged over such a long period becomes a major hurdle. How do you make a chorus compelling after its tenth or twentieth repetition? How do you maintain narrative interest without becoming redundant?
Consider the constraints of radio. DJs and program directors have always worked within time slots. A 3-minute song fits perfectly between commercials and allows for a good number of tracks in an hour. A 60-minute song would consume an entire hour of programming by itself, making it impractical for most terrestrial radio stations. Even digital platforms, while offering more flexibility, are influenced by user behavior. Most listeners prefer shorter, easily shuffled tracks that fit into their daily routines – commuting, working out, or background listening.
Delving into the Genres Where Hour-Long Songs Might Exist
So, where do these epic, hour-long musical journeys typically reside? They are not found in your average Top 40 charts. Instead, you’ll need to explore some of the more experimental, niche, and avant-garde corners of the music world. These genres often prioritize artistic expression, sonic exploration, and immersive listening experiences over commercial appeal.
Ambient Music and Drone
Perhaps the most fertile ground for extended compositions is ambient music and its subgenre, drone music. Ambient music, pioneered by artists like Brian Eno, focuses on atmosphere and mood rather than traditional song structures or melodies. It’s designed to be “ignorable” as much as it is interesting, capable of fading into the background or demanding focused attention. Drone music takes this further, often built on sustained, repetitive sonic tones or chords. The intention here is not to tell a story with a beginning, middle, and end in the conventional sense, but to create a sonic environment that the listener can inhabit. Many ambient and drone artists release albums with single tracks that can easily exceed 30 minutes, and some will certainly push past the 60-minute mark. These pieces are less about “songs” and more about “soundscapes” or “experiences.” Artists like Stars of the Lid, Tim Hecker (though not exclusively hour-long), and Eluvium are known for their sprawling, lengthy compositions.
Electronic Music (Experimental & Psychedelic Trance)
Within electronic music, especially in its more experimental and psychedelic subgenres, you can find artists who stretch the boundaries of track length. Psychedelic trance, for instance, often features long, evolving tracks that are designed to take the listener on a sonic journey, particularly in a live club or festival setting. These tracks can build layers of sound, introduce new melodic elements, and shift in intensity over considerable durations. Artists in this scene might release tracks that are 15, 20, or even 30 minutes long as standard. Occasionally, special releases or live sets might feature exceptionally long, continuous pieces. Similarly, experimental electronic artists often prioritize deep sonic exploration, and a 60-minute piece might be the perfect canvas for them to develop complex sonic textures and evolving patterns without the need for abrupt changes or commercial hooks.
Post-Rock and Progressive Rock (Extended Compositions)
While not always reaching the full hour, post-rock and progressive rock have a long tradition of creating longer, more complex musical pieces. Bands like Godspeed You! Black Emperor, Explosions in the Sky (post-rock), and King Crimson, Pink Floyd, Yes (progressive rock) are known for tracks that extend well beyond the typical song length, sometimes incorporating multiple movements or distinct sections within a single composition. These are often considered “epics” rather than simple songs. While a true 60-minute single track is less common in these genres than, say, a 20-minute suite, the *spirit* of extended musical narratives is very much alive. You might find live recordings or special album editions that contain very long improvisations or continuously performed pieces that approach or exceed the hour mark. These pieces often rely on instrumental prowess, dynamic shifts, and thematic development to maintain listener interest.
Avant-Garde and Classical Contemporary Music
The realm of avant-garde and contemporary classical music is where the concept of a “song” can become quite fluid. Composers in these fields are less bound by popular music conventions and more driven by conceptual exploration and pushing the boundaries of sound and form. Here, a piece lasting an hour or more is not uncommon. These works are often performed by orchestras, chamber ensembles, or solo instrumentalists and might explore complex harmonic structures, extended techniques, and abstract musical ideas. Composers like John Cage, Karlheinz Stockhausen, and La Monte Young have created works that are incredibly long, conceptual, and challenge our very definition of music. For instance, La Monte Young’s “The Well-Tuned Piano” can last for hours. While not “songs” in the conventional sense, they are musical compositions of significant duration.
Noise Music
Noise music, a genre that utilizes sound as its primary element, often embraces extreme durations. The focus is on texture, intensity, and the exploration of sound itself. Hour-long or even multi-hour pieces are not unusual within this genre, as artists aim to create immersive, often challenging, sonic environments. The sustained nature of noise can be hypnotic or overwhelming, and the lack of traditional musicality means that duration is less of a barrier to conceptual integrity.
Why Artists Create Hour-Long Songs: The Motivations Behind the Marathon
When an artist decides to craft a piece of music that stretches for an hour or more, it’s rarely a casual decision. There are profound artistic motivations driving such an endeavor. It’s about more than just filling time; it’s about creating an experience that cannot be achieved through shorter formats.
Immersive Sonic Journeys
For many artists in the genres mentioned above, the primary goal is immersion. A song that lasts an hour isn’t just listened to; it’s experienced. It’s an invitation for the listener to enter a sonic world, to lose themselves in the ebb and flow of sound. This is particularly true in ambient, drone, and psychedelic electronic music. The extended duration allows for gradual evolution of textures, subtle shifts in mood, and the development of complex sonic landscapes. It’s about creating a meditative or hypnotic state, where the listener can detach from external distractions and become fully present with the music. My own experience with that 58-minute track was exactly this – it felt like stepping into a different dimension, where time seemed to slow down and the outside world faded away.
Narrative and Thematic Development
While not always a linear narrative, hour-long songs can offer a profound depth of thematic exploration. In progressive rock or certain experimental electronic pieces, the extended format allows for the development of intricate musical ideas, recurring motifs that evolve over time, and dynamic arcs that mimic storytelling. Think of it like a novel versus a short story. The longer format allows for more complexity, character development (in a musical sense), and thematic exploration. An artist might use a full hour to explore a single emotion, a philosophical concept, or a sonic texture in its entirety, without the need to conform to the demands of conventional song structure or repetition.
Artistic Statement and Pushing Boundaries
Creating a song of exceptional length can itself be an artistic statement. It’s a deliberate act of defiance against commercial pressures and conventional expectations. For artists who are not concerned with mainstream appeal, crafting an hour-long piece can be a way to showcase their commitment to their vision, their technical skill, and their willingness to challenge listeners. It demands a certain level of dedication from the audience, and this shared commitment can foster a deeper connection between the artist and their listeners. It’s a way of saying, “This is the music I want to make, and if you’re willing to go on this journey with me, you’ll find something unique.”
Exploration of Sound and Improvisation
For some artists, particularly in jazz, noise, or experimental electronic music, extended durations provide the space for deep improvisation and sonic exploration. A 60-minute piece might be a live recording of an extended improvisation session, where musicians explore the possibilities of their instruments and their collective interaction without the constraints of a predetermined structure. This allows for spontaneous creativity and the discovery of unexpected musical moments. The sheer length can be a catalyst for these explorations, allowing ideas to develop organically and to reach conclusions that a shorter format wouldn’t permit.
A Different Kind of Listening Experience
Ultimately, artists who create hour-long songs are often catering to a specific type of listener. These are individuals who seek out music not just for passive enjoyment, but for a profound, engaging experience. They are willing to dedicate significant time and attention to a single piece, to be transported, challenged, or soothed by the music. The artist provides the opportunity for this deep engagement, and the listener accepts the invitation. It’s a symbiotic relationship built on a shared appreciation for the power of extended musical forms.
How to Find Songs That Last 1 Hour (or Close To It)
Discovering music that fits the “hour-long song” criteria can feel like a treasure hunt, but with the right approach, you can unearth some truly remarkable pieces. It requires digging beyond the surface of popular streaming services and exploring more specialized platforms and communities.
Leveraging Music Streaming Platforms with Advanced Search
While your standard Spotify or Apple Music search might not directly filter by duration, you can use them creatively.
- Genre Exploration: Start with the genres identified earlier: ambient, drone, experimental electronic, post-rock, psychedelic trance, avant-garde. Dive deep into these categories.
- Artist Discovery: Once you find an artist known for longer tracks, explore their discography. Many artists will have albums where individual tracks are exceptionally long.
- Playlist Curation: Search for user-created playlists with terms like “long ambient tracks,” “epic compositions,” “drone music,” or “extended electronic journeys.” These playlists can be goldmines.
- Album Track Analysis: Sometimes, an entire album might consist of just one or two very long tracks. Look for albums with very few tracks (e.g., 1-3) and check the listed durations.
Specialized Music Platforms and Communities
Certain platforms are specifically geared towards more experimental and in-depth music discovery:
- Bandcamp: This platform is incredibly popular with independent and experimental artists. You can often filter by genre and look at track lengths directly. Many artists release single-track albums or exceptionally long pieces here. Search using keywords related to the genres mentioned.
- Discogs: While primarily a database for physical music releases, Discogs also has a vast amount of information on track lengths. You can search for artists and albums, and then check the track listings for exceptionally long songs.
- Rate Your Music (RYM): This community-driven site allows users to rate and review music. You can browse by genre and sort by various metrics, sometimes leading to discovery of longer pieces.
- Forums and Online Communities: Websites like Reddit have subreddits dedicated to specific genres (e.g., r/ambient, r/drone, r/postrock, r/experimentalmusic). These communities are excellent for asking for recommendations and discovering hidden gems. Members often share their favorite long tracks.
Looking at Specific Artists and Works (Examples)
While avoiding an exhaustive list, here are some artists and types of works where you’re likely to find tracks approaching or exceeding the hour mark. Remember, exact durations can vary, and many are closer to 45-60 minutes than precisely 60:
- Stars of the Lid: Known for their epic, long-form ambient pieces. Albums like “And Their Refinement of the Decline” feature tracks that are incredibly substantial.
- Eluvium: Similar to Stars of the Lid, Eluvium creates vast sonic landscapes that often comprise very long, single-piece albums or tracks.
- Tim Hecker: While not all his tracks are hour-long, Hecker’s experimental electronic work often features extended pieces that are deeply immersive.
- Sunn O))) (Drone Metal): This band is a prime example of drone music, with many of their compositions being exceptionally long and designed for intense sonic immersion.
- Godspeed You! Black Emperor (Post-Rock): While their songs are often structured into movements, many individual pieces or suites can extend to 15-25 minutes, and their live performances can be even more expansive.
- Lustmord (Dark Ambient): A pioneer of dark ambient, Lustmord’s work often involves deep, atmospheric soundscapes that can be very lengthy.
- Certain Experimental Electronic Artists: Look for artists releasing on labels known for avant-garde electronic music.
- La Monte Young: For a truly extreme example in contemporary classical, his work “The Well-Tuned Piano” is famous for its immense duration.
When searching, be prepared that “a song that lasts 1 hour” might not always be a single, monolithic track. Sometimes it’s a continuous piece presented as an album, or a very long, multi-part suite that functions as a single listening experience.
The Listener’s Perspective: Committing to an Hour of Music
Engaging with a song that lasts an hour is a commitment. It’s an act that contrasts sharply with the fragmented, on-demand nature of modern media consumption. What drives a listener to dedicate such a significant chunk of time to a single piece of music?
Seeking Deep Immersion and Escape
For many, hour-long songs offer an escape from the everyday. They provide an opportunity to disconnect from the constant barrage of information and notifications and to enter a focused, immersive state. This is especially true for listeners of ambient, drone, and psychedelic music, who often seek music that can induce meditative states, aid in concentration, or simply provide a vast sonic space to get lost in. It’s about creating a dedicated listening session, a ritual even, where the music becomes the sole focus for an extended period.
Appreciation for Complexity and Nuance
Hour-long songs are rarely simple. They often possess a level of complexity, nuance, and subtle development that smaller tracks cannot achieve. Listeners who appreciate intricate sound design, evolving musical narratives, and the exploration of sonic textures will find these extended pieces rewarding. It’s like dissecting a complex painting or reading a dense novel; the deeper you look, the more you discover. These pieces invite repeated listening, with new details and emotional resonances revealing themselves over time.
A Different Kind of Emotional Arc
The emotional journey of a 60-minute song can be far more profound and varied than that of a 3-minute track. Instead of a single, concentrated emotion, an hour-long piece can encompass a vast spectrum of feelings, shifting moods, and evolving atmospheres. It can mirror the arc of a life experience, a dream, or a long journey. Artists who craft these pieces are often skilled at guiding the listener through these emotional landscapes, creating a cathartic or transformative experience that lingers long after the music has ended.
The Challenge and Reward
There’s an inherent challenge in dedicating an hour to a single song, and for many listeners, overcoming this challenge is part of the reward. It requires patience, focus, and an openness to experiences that lie outside the norm. This act of commitment can lead to a deeper appreciation for the music and a stronger connection with the artist. It’s a different way of engaging with art, one that values depth over accessibility and profound immersion over fleeting enjoyment.
When I first listened to that hour-long track, I was initially a bit apprehensive. Could I really stay engaged for that long? But as the music unfolded, my apprehension faded, replaced by a sense of wonder and deep connection. It was a journey, and the reward was a feeling of being profoundly moved and transported. It taught me that sometimes, the most rewarding experiences require us to set aside our usual habits and embrace the unconventional.
Is a “Song” Still a “Song” at 1 Hour?
This is a philosophical question that touches on the very definition of music. If we define a “song” by its adherence to traditional structures (verse-chorus, bridge, etc.) and its typical duration, then an hour-long piece might strain that definition. However, if we define a song more broadly as a composed piece of music intended for listening, then duration becomes less of a defining factor.
- Traditional Song Form: Most hour-long pieces do *not* follow a standard verse-chorus structure. They are more akin to suites, symphonies, or continuous sonic explorations.
- Intent: The artist’s intent is key. If they conceive of it as a single, unified musical statement, then it functions as a song, albeit an unconventional one.
- Listener Experience: From the listener’s perspective, if it’s experienced as a cohesive musical piece, then calling it a “song” feels appropriate, even if it’s a marathon.
- Genre Conventions: In genres like ambient, drone, or experimental electronic, the concept of a “track” or “piece” often supersedes the traditional “song” label, and these pieces can be extremely long.
Ultimately, while they may not fit the mold of a pop song, these extended musical works are undeniably powerful and intentional artistic creations. The label matters less than the experience they provide.
Frequently Asked Questions (FAQ)
How can I find hour-long songs on Spotify or Apple Music?
Finding hour-long songs on mainstream streaming platforms like Spotify and Apple Music can be challenging because they don’t typically have a direct search filter for track duration. However, you can employ a few strategies:
Firstly, focus on genres known for extended compositions. Search for terms like “ambient,” “drone,” “experimental electronic,” “post-rock,” “psychedelic trance,” or “avant-garde.” Within these genres, explore albums with very few tracks (e.g., 1-3 tracks per album). Many artists in these genres release entire albums that are essentially single, long-form pieces or tracks that are 30-60 minutes long. Look for artists who are pioneers or prominent figures in these genres, as they are more likely to experiment with duration. For example, artists like Stars of the Lid, Eluvium, or Lustmord are good starting points. You can also try searching for user-created playlists. Many users curate playlists with titles like “Epic Tracks,” “Long Ambient Journeys,” or “Hour-Long Music.” These playlists, though not always featuring precisely 60-minute tracks, will often contain pieces that are significantly longer than average.
Secondly, if you discover an artist who creates longer tracks, delve into their discography. Often, a band or solo artist will have one or more albums where individual songs or entire albums are structured as single, extended pieces. Check the track durations listed for each song. While you might not find a perfect 60-minute track every time, you’ll likely find many pieces that are 15, 20, 30 minutes, or even longer, which can be a satisfying discovery in itself. It’s about exploring the edges of what’s available on the platform. Remember, the goal is often to find artists who prioritize sonic exploration and immersive experiences over conventional song lengths.
Why don’t mainstream artists create hour-long songs?
The primary reason mainstream artists, particularly those in pop, rock, and hip-hop, don’t create hour-long songs is due to a confluence of factors related to commercial viability, audience attention spans, and industry standards. The music industry, especially radio and popular streaming, thrives on accessibility and broad appeal. Hour-long songs are inherently not accessible to a mass audience. Radio stations operate on strict time slots and cannot accommodate such lengthy tracks. For a pop song to gain traction, it needs to be easily digestible, memorable, and fit within a format that allows for multiple songs to be played within an hour, interspersed with commercials or other content. A 60-minute song would occupy an entire hour, drastically limiting its broadcast potential.
Furthermore, audience attention spans in the digital age are often perceived as shorter. Listeners are accustomed to quick hits, catchy hooks, and the ability to skip tracks easily. A song that demands an hour of undivided attention would likely deter a significant portion of the casual listener base. Artists aiming for widespread success must cater to these expectations. Their creative process is often guided by market research, what’s trending, and what’s likely to be picked up by labels and streaming service curators. While some artists might have the creative inclination, the commercial incentives and practicalities of the mainstream music ecosystem actively discourage the creation of such exceptionally long tracks. It’s not necessarily a lack of artistic will, but a pragmatic response to the demands and structures of the industry.
What are the benefits of listening to hour-long music?
Listening to music that is an hour long offers several distinct benefits, primarily centered around deep immersion, emotional depth, and a unique form of mental engagement. Firstly, these extended pieces are unparalleled in their ability to create an immersive sonic environment. They allow the listener to enter a different state of mind, often akin to meditation or deep focus. This is particularly true for ambient and drone music, where the slow evolution of soundscapes can help calm the mind, reduce stress, and block out external distractions. By dedicating an hour to a single piece, you are essentially creating a dedicated listening session, a ritual that allows for a profound escape from the pressures of daily life.
Secondly, hour-long compositions offer a much richer and more nuanced emotional journey. Unlike shorter songs that might convey a single, concentrated emotion, extended pieces can explore a wide spectrum of feelings, developing complex emotional arcs and subtle shifts in mood. This can be incredibly cathartic and transformative, allowing listeners to process emotions or explore different psychological states in a safe and controlled way. The extended duration allows for themes to be developed, variations to emerge, and a sense of narrative to build, creating a more profound connection with the music. Finally, engaging with such lengthy music can foster patience, focus, and a deeper appreciation for musical artistry. It challenges the listener to invest their time and attention, rewarding them with discoveries that might be missed in shorter formats. It’s an exercise in deep listening and can lead to a more profound and lasting impact than fleeting, easily consumed content.
Are there any artists who exclusively make hour-long songs?
While it’s rare to find artists who *exclusively* create songs that are precisely 60 minutes long, there are certainly artists and projects where the vast majority, if not all, of their output consists of extremely long, single-track compositions that often hover around or exceed the hour mark. These artists typically operate within genres like drone, ambient, experimental electronic, or noise music, where extended duration is a core element of their artistic expression. For example, in the drone and ambient scenes, it’s common for an album to consist of just one or two tracks, each stretching for 45 minutes to over an hour. Artists such as Stars of the Lid, Eluvium, or Lustmord are often associated with this style of composition. Some projects might even present an entire album as a single continuous piece of music, effectively making the entire album a single “song” or composition that is significantly longer than an hour.
However, finding artists who *only* release tracks of exactly 60 minutes is highly improbable. The creative process is rarely so rigidly defined. An artist might release a 45-minute track one time and a 70-minute track another. The key is that their artistic vision prioritizes long-form sonic exploration over traditional song structures and durations. These artists are not aiming for hit singles but for immersive, extended listening experiences. Their entire body of work would reflect this philosophy, making them the closest you’ll get to artists who exclusively create hour-long (or longer) musical pieces. You’ll need to explore niche genres and independent platforms like Bandcamp to discover these creators, as they are unlikely to be found on mainstream radio or chart-topping playlists.
What is the longest officially released song ever?
The question of the “longest officially released song ever” can be a bit of a moving target and depends on how you define “song” and “officially released.” However, some notable examples push the boundaries significantly. In the realm of ambient and drone, projects have emerged with durations that dwarf traditional songs. For instance, the ambient artist **Eldbjørg Raknes** released “Smalt og Salig” which is over 3 hours long, often presented as a single track. In experimental music, **Eartheater** has a track titled “Longing for a New Year” that is reported to be over 6 hours long. However, if we consider extremely long pieces that are more conceptual or performance-art oriented, the boundaries blur even further. American composer **La Monte Young** is known for his extremely long, minimalist compositions, such as “The Well-Tuned Piano,” which can last for several hours in performance. Another notable example is the ambient music project **The Dead Texan**, which has released tracks that extend for over 7 hours. These are less “songs” in the conventional sense and more like immersive sonic environments or ongoing musical processes. The Guinness World Record for the longest officially released song has been held by various artists over time, often exceeding 24 hours, but these are typically considered conceptual art pieces rather than what most people would recognize as a typical song.
It’s important to distinguish between a continuous musical composition and something that might be an extended mix or a compilation. The examples above refer to single, unified pieces of music. These are not meant for casual listening but are significant artistic statements requiring a substantial commitment from the listener. They highlight the extreme possibilities of musical duration when artists are unconstrained by commercial expectations or traditional song structures.
The Future of Extended Music (A brief perspective)
While I’m focused on providing current information, it’s worth noting that the digital age has paradoxically made both extreme brevity and extreme length more accessible. As artists continue to explore sonic boundaries, and as listeners seek more profound and immersive experiences, we may see a continued, albeit niche, interest in longer musical forms. Streaming platforms, while favoring shorter tracks for playlisting, do offer the technical capability for much longer pieces. The challenge remains in how these pieces find their audience and are integrated into listening habits. The artists who create them will likely continue to do so for their own artistic imperatives, finding dedicated listeners who appreciate the unique journey these extended musical works provide.
Conclusion: The Rarity and Reward of the Hour-Long Song
So, to circle back to our initial question, how many songs last 1 hour? The answer is: not many in the grand scheme of music, but a significant number if you know where to look within specific genres. They are rare treasures, outliers in a world often dominated by brevity. These hour-long compositions are not mere extensions of familiar song structures; they are intentional journeys, sonic landscapes, and artistic statements designed to immerse, challenge, and transport the listener. From the pulsating depths of drone to the evolving textures of experimental electronic music, and the sprawling narratives of post-rock, these extended pieces offer a unique and profound listening experience. For the artist, they are a canvas for deep exploration; for the listener, they are an invitation to a world where time bends and the music takes center stage. While they may never top the charts, the hour-long song holds a special, albeit niche, place in the heart of music discovery and appreciation.
