Playing the Organ
The numbers (16', 5-1/3', etc.) printed on the knob of each harmonic bar indicate the
pitch of that bar in “feet.” The pitch of each harmonic bar plays an important role in
creating the tone. The 8' pitch is the basic pitch of the sound, and the sound is created
based on this 8' pitch.
The pitches of the harmonic bars are related as follows.
