Reed excitation injects all harmonics even when resonator rejects even modes

Evidence

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 Displacement Figure 4. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1255
