Spectra of only odd harmonics produce a clarinet-like timbre

Evidence

65 Organ stops reinforcing odd harmonics: The stops that reinforce the first five odd harmonics (1f0, 3f0, 5f0, 7f0, 9f0) are dra wn while the note G4(392Hz) is held. The stops on this instrument are: chimney flute 8’, nazard 2 2/3’, tierce 1 3/5, septième 1 1/7’ and non e 8/9’. This enables the effect of each stop to be heard as it contri butes to the timbre of the sound: a form of “analytic” listening. Then the note is repeated a few times and a short tun e is played; now the timbre of the notes is usually heard as a whole: a form of “holistic” listening. Notice that the final effect is somewhat clarinet-like du e to the spectrum consisting o f the odd harmonic s eries (see Section 4. — David Howard, Jamie Angus, coustics and Psychoacoustics, 3014

Categorization

• XREF: Connects to the reader’s existing psychoacoustics reading on timbre and harmonic series from earlier chapters, and echoes how clarinet physics (closed pipe) yields odd harmonics.
• SEED: The odd-harmonic clarinet sound recurs in many synth patches and ring-mod timbres — a possible angle on how perception of ‘instrument nature’ is really spectral shape identification.
