Adding a harmonic-reinforcing organ stop boosts all multiples of that harmonic

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.
