Timbre as an Expressive Tool
Musicians often focus on pitch and rhythm as they prepare for a performance, yet some of our most special experiences of music are deeply reliant on timbre and texture. How can we bring these meaningfully into the study of creating music?
Many of the factors that musicians describe as contributing to “musicality” exist on a spectrum: timing (fast to slow), volume (loud to soft), register (high to low), and dissonance to consonance. To these, we can now add some of our timbre spectra, particularly noisy to pure, bright to dark, and percussive to legato. Many of these spectra map onto each other in intuitive ways; for example, something that is highly dissonant may benefit from a harsh, noisy timbre, while something that is soft may sound just right when performed legato with a dark tone.
Musicians often use timbre to highlight the textural roles of different parts within an ensemble. Melody parts are often brighter to ensure that they are perceived clearly. For other parts that do not need to be heard individually, musicians often focus on “blending,” or making the parts sound unified—almost as if they were created by a single instrument or voice making multiple simultaneous sounds. In choirs, for example, directors often focus on making sure that their singers take the same approach to creating each vowel to ensure that their timbre is unified. In ensembles of mixed instrument types like wind bands or symphony orchestras, this kind of unification of timbre across parts may be more difficult but is still highly effective. Directors of these ensembles use many methods to unify timbre, including using metaphors, demonstrating a desired timbre through singing, and giving advice on appropriate approaches to technique, such as breath support or embouchure.
Activity: Shape music through timbre
Goal: Take an intentional approach to using timbre in service of musicality.
Before you start: You will need your primary instrument (your voice is fine) and some memorized or notated music. The music may be something you are working on or excerpts from a sight-reading manual that are of sufficient simplicity to allow you to focus on timbre. It is simplest and quickest to work with a short span of music, such as a phrase or two, but this can also be effective over longer sections or even whole movements/pieces.
Instructions:
- Create three different plans for how you might approach the music in terms of timbre. You could consider different spectra in each plan (e.g., noisy/pure, bright/dark) or trying out different approaches to changing timbre across the course of the music (e.g., “I will try playing it all dark and muted” vs. “I will start with a pure tone, slowly shift to a much noisier/harsher tone at the climax, and then return to the pure tone at the end”).
- Perform the music in each of the three ways, focusing on making your timbral plan as musical and effective as possible each time.
- Evaluate: which performance did you like best and why? If others were listening, which did they prefer?
Activity: Listen for timbral shape
Goal: Pay attention to timbre and describe how it contributes to our experience of music.
Before you start: You will need access to a performance of some music. This performance can be a recording . If you have multiple recordings or performances of a single piece of music, this will allow comparison of different musicians’ choices. A few examples are in the playlist below.
Instructions:
- Listen to each performance or a preselected section of the performance and describe the timbres that you hear in as much detail as you can.
- For each individual performance, describe how timbral choices changed over time and/or responded to other elements of the music, such as volume, consonance/dissonance, or register.
- If you listened to multiple performances, which one used timbre most effectively and why/how?
Activity: Perfect your blend
Goal: Unify timbre across an ensemble.
Before you start: You will need an ensemble; 4–6 musicians is a nice size to allow you to hear both individual timbres and the overall sound. This activity will be easiest with a group of musicians all playing the same instrument or the same family of instruments (e.g., woodwinds, voices); it will be more difficult with a mixed ensemble. You may wish to apply this activity to a single tone or chord or to a short excerpt of music; if you choose the latter, it may be helpful to use music that is relatively sustained and homophonic to facilitate a focus on blend. Each time you do this activity, one person will act as director and the others as performers.
Instructions:
- The director gives the ensemble instructions on the desired approach to timbre.
- The ensemble then plays/sings the single tone, chord, or short excerpt of music while the director listens carefully, evaluating how well-blended the ensemble is and whether individual timbres stick out.
- Repeat steps 1 and 2 as appropriate until the ensemble sounds as much as possible like a single instrument/voice making many sounds.
