An assembly of diverse instruments can play the exact same notes and yet produce a distinct sound, because of an element of music called timbre. What is timbre in music? Timbre definition is described as the ‘colour’ or ‘characteristic’ of a sound produced by a voice or musical instrument that helps distinguish sound from one to another.
Understanding what timbre is in music will help you recognize the distinctive characteristic between the tone colour or sound quality you want to produce. Let’s start from the beginning!
What is Timbre in Music
It is hard to explain timbre definition in words because it is influenced by various mechanisms in music perception and understanding. For musical instruments, timbre’s effect can be found when two or more musical instruments play identical pitches at identical volume and still produce distinct musical sound.
The production of the primary pitches and overtones are crucial to explain how an instrument can play the exact same note with different sound. The timbre of music as auditory senses produced by a sound wave is highly dependent on its waveform. It varies according to the presence of the overtone number (harmonics), frequency, and relative strength. The frequency spectrum is the distribution of sound wave amplitudes, which indicates whether the music is loud or soft.
One good way to do it is comparing different families of instruments such as brass instruments that have a distinct timbre than string instruments. Even within a given family, tone colours can be different; take the clarinet and the trumpet for example. Both clarinet and trumpet are wind instruments, yet their tone colours are different. The pitch may be the same, but the timbre of each sound is very different. As a result, the listener can easily hear that the note is being played by 2 different instruments.
What are Tones in Music & The Difference Between Timbre and Tone
While learning about the basics of timbre, we couldn’t forget about what are tones in music. Tone can be used to describe intervals in a scale, specific musical notes, or the quality of a sound. What does it mean? In Western music theory, a scale is a sequence of notes chosen from the 12 available pitches.
Tone is used to measure and describe the gap or from one note to the higher or lower neighboring note on a scale. This interval is called a semitone. For example, the intervals from C to B or E to F on the piano are both semitones. If the interval appears to have two semitones, for instance the interval F to G, A to B, and C to D is called a ‘whole-tone’ or ‘tone’. Both semitone and whole-tone are useful in building scales, chords, melodies and understanding music transposition
Another reference of tone in music is a single frequency played by a musical instrument. On a piano keyboard, when you depress the A key it sounds the musical tone. In another case, if you press the adjacent key right above it, it sounds the musical tone A sharp.
Lastly, tone refers to the sound qualities of a particular sound. Tone differences are related to the fundamental frequency (the sound played) and the balance of overtones. Different instruments produce these at different rates. A pure tone produces only the fundamental frequency and no overtones. Complex tones produce both fundamentals and overtones. Computer software can generate waveform images from audio tones. These wave-forms vary by instrument or by the addition of accessories such as guitar amplifiers.
While the word tone is used interchangeably with timbre, both have different functions. Timbre differs from tone because it focuses on what distinguishes the sound of one instrument to another. Simply put, timbre describes the “character” or “colour” of a sound, while tone focuses on vocal or instrumental sounds that indicate pitch relative to their position on the scale.
How to Describe Timbre in Music
The unique sound quality of an instrument is limitless, so describing what are timbres of a sound using mere words could be difficult. In this case, adjective words are commonly used to convey the subjective qualities of the sound, such as:
- Piercing: high-pitched, sharp sound
- Nasal: sounds created by blocking the lips (such as ‘m’, ‘n’, ‘ng’) few overtones and loud basic pitch
- Bright: high-pitched, clear sound
- Flat: lower in pitch
- Silky: smooth & soft voice
- Mellow: relaxed, pleasant sound
- Warm: bass, lower frequency sound and vocals stand out
- Breathy: dominating sound of airflow
- Vibrato: a lengthy note that rapidly changes in frequency or tone
You might also describe what are timbres in terms of its texture, thickness, or richness. A timbre is a complex and subtle aspect of sound that can be difficult to describe in words, but is nevertheless an essential part of our experience of music and other types of sound. To make it easier these are how different instruments can be described in terms of timbre:
Timbre example in string instruments:
- Piano: The musical timbres of a piano can be described as rich, full, and percussive, with a wide range of dynamics and a long sustain.
- Violin: The musical timbres of a violin can be described as warm, expressive, and versatile, with a rich and complex sound.
- Electric guitar: The musical timbres of an electric guitar can be described as distorted, crunchy, and aggressive, with a wide range of effects and a powerful sound.
- Bass guitar: The The musical timbres of a bass guitar can be described as deep, resonant, and groovy, with a solid and powerful sound.
Timbre example in wind instruments:
- Flute: The musical timbres of a flute can be described as airy, delicate, and ethereal, with a pure and sweet tone colour.
- Saxophone: The musical timbres of a saxophone can be described as smooth, soulful, and expressive, with a rich and warm tone colour.
- Trumpet: The musical timbres of a trumpet can be described as bright, piercing, and brass-like, with a clear and focused sound.
- Flute: The musical timbres of a flute can be described as airy, delicate, and ethereal, with a pure and sweet tone colour.
- Saxophone: The musical timbres of a saxophone can be described as smooth, soulful, and expressive, with a rich and warm tone colour.
Timbre example in percussion instruments:
- Drum set: The musical timbres of drums can vary widely depending on the type of drum, but generally, they have a deep and resonant sound. Snare drums have a sharp and crisp tone, while bass drums have a booming and thumping sound.
As it is a complex and subjective quality, different people may hear it differently and use different words to describe it based on personal perception and cultural associations. Overall, timbre is an essential element of musical expression, and understanding how to describe it can help you appreciate the unique qualities of different instruments and styles of music.
Factors that Affect the Timbre in Music
Timbre is determined by a combination of factors, including the shape and the size of the sound wave, the harmonic content of the sound, the materials used to create the sound, the acoustic environment in which the sound is heard, and the way in which the sound is produced.
The shape and size of an instrument can affect the way sound waves are produced and propagated, which can impact the overall timbre of the sound. Few examples on how each musical instrument’s shape affect the timbre in music, such as:
String Instruments
The shape of the body of a string instrument, such as a violin or guitar, affects the way in which the sound waves produced by the strings resonate within the instrument. The size and shape of the body determine the volume, tone colour, and resonance of the instrument. A larger body typically produces a fuller, warmer sound, while a smaller body may produce a brighter, more focused sound.
Wind Instruments
The shape of the bore, or internal tube, of a wind instrument affects the way in which the air column vibrates when the player blows into the instrument. The shape of the bore can influence the pitch, tone colour, and volume of the sound produced. For example, a flute has a long, narrow bore, which produces a clear, bright sound, while a saxophone has a wider bore, producing a more mellow sound.
Percussion instruments
The shape of a percussion instrument can affect its timbre by altering the way in which the instrument resonates and produces sound. For example, a drum with a deeper body will produce a lower pitch, while a shallower drum will produce a higher pitch.
While talking about shape, it is also worth mentioning the effect of the playing technique or the way a musician plays an instrument. The way an instrument produces sound through plucking, bowing, or striking a key, creates the desirable sound in a way each instrument produces their timbre and gives subtle yet a big impact in producing the timbre of the sound.
Why is Timbre Important?
Timbre is around us. It brings us the distinction of different sounds between a piano, a guitar, or even various human voices. By recognizing the characteristic, such as smoothness, bass, or tenseness in each instrument and person’s voice, we instinctively identify familiar voices.
Sounds we can easily notice could be the ‘ta-dum’ tone from Netflix, the ringing of sleigh bells associated with Christmas, the Middle Eastern musical instrument linked with Islamic music, and many more. A memorable and unique sound helps the listener to easily identify and memorize the product without further thinking.
Similarly, as a content creator, the timbre of sounds can instantly grab attention or add a layer of information to your product. The use of timbre on digital platforms stems from the need to convey information or emotion through media other than images.
Conclusion
As an identifier, timbre manipulation is an essential part of sound design practice. Whenever you produce a sound or modify an existing sound for your branding, you should consider its unique timbral qualities. Pay attention to each individual component as you blend to get a more objective view of the sounds you’re working with. Timbre plays a big part in each element and the overall quality of the sound.
