In music, timbre, also known as tone color, ( /ˈtæmbər/ TAM-bər or /ˈtɪmbər/; French: [tɛ̃bʁ]) is the quality of a musical note or sound or tone that distinguishes different types of sound production, such as voices and musical instruments, string instruments, wind instruments, and percussion instruments. The physical characteristics of sound that determine the perception of timbre include spectrum and envelope. In psychoacoustics, timbre is also called tone quality and tone color.

In simple terms, timbre is what makes a particular musical sound different from another, even when they have the same pitch and loudness. For instance, it is the difference between a guitar and a piano playing the same note at the same loudness. Experienced musicians are able to distinguish between different instruments based on their varied timbres, even if those instruments are playing notes at the same pitch and loudness.

Synonyms[link]

Tone quality and color are synonyms for timbre, as well as the "texture attributed to a single instrument". Hermann von Helmholtz used the German Klangfarbe (tone color), and John Tyndall proposed an English translation, clangtint. But both terms were disapproved of by Alexander Ellis, who also discredits register and color for their pre-existing English meanings (Erickson 1975, 7).

The sound of a musical instrument may be described with such words as bright, dark, warm, harsh, and other terms. There are also colors of noise, such as pink and white.

In visual representations of sound, timbre corresponds to the shape of the image (Abbado 1988, 3).

American Standards Association definition[link]

The American Standards Association definition 12.9 of timbre describes it as "that attribute of sensation in terms of which a listener can judge that two sounds having the same loudness and pitch are dissimilar", and a note to this definition adds that "timbre depends primarily upon the spectrum of the stimulus, but it also depends upon the waveform, the sound pressure, the frequency location of the spectrum, and the temporal characteristics of the stimulus" (American Standards Association 1960, 45).

Attributes[link]

Timbre has been called a "wastebasket" attribute (Dixon Ward 1965, 55) or category (Tobias 1970, 409), or "the psychoacoustician's multidimensional waste-basket category for everything that cannot be labeled pitch or loudness" (McAdams and Bregman 1979, 34).

Many commentators have attempted to decompose timbre into component attributes. For example, J. F. Schouten (1968, 42) describes the "elusive attributes of timbre" as "determined by at least five major acoustic parameters", which Robert Erickson (1975) finds "scaled to the concerns of much contemporary music":

1. The range between tonal and noiselike character.
2. The spectral envelope.
3. The time envelope in terms of rise, duration, and decay (ADSR—attack, decay, sustain, release).
4. The changes both of spectral envelope (formant-glide) and fundamental frequency (micro-intonation).
5. The prefix, or onset of a sound, quite dissimilar to the ensuing lasting vibration.

(Erickson 1975, 6) gives a table of subjective experiences and related physical phenomena based on Schouten's five attributes:

Harmonics[link]

The richness of a sound or note produced by a musical instrument is sometimes described in terms of a sum of a number of distinct frequencies. The lowest frequency is called the fundamental frequency and the pitch it produces is used to name the note, but the fundamental frequency is not always the dominant frequency. The dominant frequency is the frequency that is most heard, and it is always a multiple of the fundamental frequency. For example, the dominant frequency for the transverse flute is double the fundamental frequency. Other significant frequencies are called overtones of the fundamental frequency, which may include harmonics and partials. Harmonics are whole number multiples of the fundamental frequency, such as ×2, ×3, ×4, etc. Partials are other overtones. Sometimes there are also subharmonics at whole number divisions of the fundamental frequency. Most western instruments produce harmonic sounds, but many instruments produce partials and inharmonic tones, such as cymbals and other indefinite-pitched instruments.

When the orchestral tuning note is played, the sound is a combination of 440 Hz, 880 Hz, 1320 Hz, 1760 Hz and so on. Each instrument in the orchestra will produce a different combination of these frequencies, as well as harmonics and overtones. The sound waves of the different frequencies will overlap and combine, and it is the balance of these amplitudes that is a major factor in the characteristic sound of each instrument.

William Sethares wrote that just intonation and the western equal tempered scale are related to the harmonic spectra/timbre of many western instruments in an analogous way that the inharmonic timbre of the Thai renat (a xylophone-like instrument) is related to the seven-tone near-equal tempered pelog scale in which they are tuned. Similarly, the inharmonic spectra of Balinese metallophones combined with harmonic instruments such as the stringed rebab or the voice, are related to the five-note near-equal tempered slendro scale commonly found in Indonesian gamelan music (Sethares 1998, 6, 211, 318).

Envelope[link]

A signal and its envelope marked with red

The timbre of a sound is also greatly affected by the following aspects of its envelope: attack time and characteristics, decay, sustain, release (ADSR envelope) and transients. Thus these are all common controls on synthesizers. For instance, if one takes away the attack from the sound of a piano or trumpet, it becomes more difficult to identify the sound correctly, since the sound of the hammer hitting the strings or the first blat of the player's lips are highly characteristic of those instruments. The envelope is the overall amplitude structure of a sound, so called because the sound just "fits" inside its envelope: what this means should be clear from a time-domain display of almost any interesting sound, zoomed out enough that the entire waveform is visible.

Timbre in music history[link]

The music of Debussy, composed during the last decades of the nineteenth and the first decades of the twentieth centuries, has been credited with elevating the role of timbre in music: "To a marked degree the music of Debussy elevates timbre to an unprecedented structural status; already in Prélude à l'après-midi d'un faune the color of flute and harp functions referentially" (Samson 1977,^{[page needed]}).

Psychoacoustic evidence[link]

Often listeners are able to identify the kind of instrument even across "conditions of changing pitch and loudness, in different environments and with different players". In the case of the clarinet, an acoustic analysis of the waveforms shows they are irregular enough to suggest three instruments rather than one. David Luce (1963, 16) suggests that this implies "certain strong regularities in the acoustic waveform of the above instruments must exist which are invariant with respect to the above variables". However, Robert Erickson argues that there are few regularities and they do not explain our "powers of recognition and identification". He suggests the borrowing from studies of vision and visual perception the concept of subjective constancy (Erickson 1975, 11).

Psychoacoustic experiments from the 1960s onwards tried to elucidate the nature of timbre. One method involves playing pairs of sounds to listeners and then using a multidimensional scaling algorithm to aggregate their dissimilarity judgements into a timbre space; the most consistent outcomes from such experiments are that brightness or spectral energy distribution (Grey 1977,^{[page needed]}), and the "bite", or rate and synchronicity (Wessel 1979,^{[page needed]}) and rise time (Lakatos 2000,^{[page needed]}), of the attack are important factors.

Timber Timbre is a Canadian folk music project, featuring Taylor Kirk, Simon Trottier and Mika Posen. The moniker refers to an early series of recordings made in a timber-framed cabin set in the wooded outskirts of Bobcaygeon, Ontario.

Timber Timbre released two albums independently before releasing a self-titled album on Out of This Spark in January 2009. They were subsequently signed to Arts & Crafts, who re-released the album on June 30 in Canada and July 28 internationally.^[1] The album was named as a longlist nominee for the 2009 Polaris Music Prize on June 15, 2009,^[2] and was deemed album of the year by Eye Weekly.^[3]

The band's song "Magic Arrow" was featured in the television show Breaking Bad, in the episode "Caballo Sin Nombre", as well as in the TV series The Good Wife, in the episode "Bitcoin for Dummies".

On June 16, 2011, the band's fourth album Creep On Creepin' On was named as a longlisted nominee for the 2011 Polaris Music Prize.^[4] On July 6, the album was named as a short listed (one of ten) nominee for the 2011 award.

Sound[link]

Timber Timbre's^[5] sound has been described as "an aesthetic rooted in swampy, ragged blues" ^[6] and "beautifully restrained blues from an alternate universe",^[7] which creates an atmosphere that is cinematic and spooky.^[8]
