What you’ll learn

  • Timbre is the mix of harmonics: the spectrum.
  • The fundamental sets the pitch. The harmonics set the character.
  • The ear separates sound into frequencies, a natural Fourier analyser.

Steps

  1. Same note, different sound
  2. Mix a timbre
  3. A clarinet’s harmonics
  4. A violin’s overtone
