Aerophone design tunes resonance modes so the instrument becomes musically usable

Evidence

In aerophones, the vibration occurs in an air column, which thus acts as a resonator in the system. An example of an aerophone is the trumpet, where the column is composed of the mouthpiece, the bore, and the bell, shown in Figure 6.4. The resonances of the trumpet remotely resemble the resonances of a tube closed at one end, as shown in Figure 2.12b on page 29. The acoustic effects of the mouthpiece and the bell, however, change the frequencies and amplitudes of the modes in a well-tuned manner to enable the musical use of the instrument. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 663
