Impedance spectrum of a Bb clarinet measured using covered fingering for D4.

Note that this very cross-fingered arrangement produces an impedance spectrum with no regular spacing of peaks below the cut-off frequency. Consequently, the sound spectrum shows a strong fundamental but weak higher harmonics, and no systematic difference between even and odd harmonics.
