Resonator geometry shapes which harmonics appear in an instrument’s sound
Evidence
The saxophone spectrum contains all harmonics since its resonator is conical. The clarinet spectrum exhibits the odd harmonics clearly as its resonator is a cylindrical pipe closed at one end (see Figure 4.18), but there is also energy clearly visible in some of the even harmonics. Although the resonator itself does not support the even modes, the spectrum of the sound source does contain all harmonics (the saxophone and the clarinet are both single-reed Clarinet FIGURE 4. — David M.
