Timbre Families — Eight Ways of Making a Sound

Timbre is not how high, but how the air is made to move

Every group below is the same melody played with a different synthetic timbre. Note that the pitches and durations are identical — only "how the sound was produced" changes.

Bowed (sustained, with vibrato)

Plucked (fast attack, short decay)

Struck (the sharpest transient)

Blown (continuous breath)

Reed (a hard edge with nasal colour)

Brass (thick and bright)

An action you can verify yourself

1. Listen only to the first (bowed) and the second (plucked); 2. Switch between them — the same melody will sound like two different instruments saying the same sentence; 3. Then listen to the third (struck) — it sounds like "spoken" rather than "sung".

The difference between those three is timbre. Their pitches, durations and order are identical.

Why timbre matters

An easily missed fact: timbre is the most "physical" layer in music.

pitch, duration and dynamics are abstract quantities — they can be written on paper;
timbre is physical — it is literally the mechanics of pushing air.

So timbre is also the layer closest to the performer. Two people playing the same piece can match pitch and match duration, and their timbre will still differ.

A common misreading

"Timbre = high register" is simply wrong. Register and timbre are independent:

a triangle is very high, yet its timbre is brittle metal;
a cello is very low, yet its timbre can be very thick;
the same instrument sounds different in its high and low registers (which is why a violin and a "low violin" are not remotely alike).

So "high equals bright" is a regularity, not a definition.

An honest note

The six groups above are six of the nine models in this site's synthesiser, and they are approximations, not samples of real instruments.

Real instruments are far richer than these — which is why this site's instrument guide (inst) demonstrates with real MIDI sound sources.

But the principle of listening is the same: watch the four dimensions — how fast the attack is, how clean the edges are, whether there is breath, whether there is vibrato.
