Organists shape timbre by selectively reinforcing harmonics of one series
Evidence
Organs have a number of stops on each manual of various footages, most of which are flues. Some are voiced to be used alone as solo stops, usually at 8′ pitch, but the majority are voiced to blend together to allow variations in loudness and timbre to be achieved by acoustic harmonic synthesis by drawing different combinations of stops. The timbral changes are controlled by reinforcing the natural harmonics of the 8′ harmonic series on the manuals (16′ harmonic series for the pedals). — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1526
Categorization
- SEED: Angle: ‘the organ as the first analog synthesizer’ — how Renaissance builders engineered Fourier synthesis by pulling knobs.
- XREF: Directly parallels the electronic additive synthesizer discussed earlier in the timbre chapter. — connects to: Organ pipes’ timbre arises from resonances cooperating with edge tone; Brass instrument design transforms odd-only pipe modes into a near-complete harmonic series — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1250; The pipe organ is history’s first additive synthesizer for timbre — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1524 (+2 more)
- corroborated: 2 independent passages support this claim — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1526
