Figure 3.5 Waveform of noise
Musical instruments like violins, pianos, clarinets, and flutes naturally emit sounds with
interesting harmonic components. Each instrument has an identifiable timbre sometimes
called its tone color that results from its shape, the material of which it is made, its resonant
structure, and the way it is played. These physical properties result in the instrument having a
characteristic range of frequencies and harmonics. (See Figure 3.6.)
