How can you describe the texture of sounds?
One aspect of sound that traditional music notation is very poorly equipped to deal with, is the texture or timbre of the sound. There is no accurate way to describe musical timbre using traditional notation.
Can you find more than your friends?
A sound’s timbre could be thought of as its fingerprint.
The particular timbre that a sound has is created by a combination of all its properties.
You might find it useful to sketch out pictures of how the sounds might look? (See also: Drawing Sounds.)
Listen to these two sound clips of traditional instruments:
An Instrument Playing the Note D2
Listen to the quality of this sound and compare it with the sound below.
A Second Instrument Playing the Note D2
Both instruments are playing the same note, but they sound very different.
Did they sound different? In what way?
This example demonstrates to us that there is much more to sound than pitch.
If we are presented with many sounds that have similar timbres, then it can be difficult to identify the number of sources.
Think, for example, of being in a crowded place (a shopping centre or a football stadium) where there are many people talking at once. We no longer hear the individual voices, but a mass sound for the whole crowd.
In this example, the many voices blend together into a cacophony of sound. Gradually as the layers of voices thin out, we begin to hear more and more details from individual phrases.
In traditional music, orchestration takes advantage of timbre, allowing musical elements to be separated and clearly distinguished.
Making music with sounds allows us to explore this idea even further and positions timbre as the most important aspect of music.
Each of these objects has a unique timbre. That is how we can tell them apart.
