HARMONIC DRAWBARS™
The 9 Drawbars (plus 2 for the Pedal) on this organ are used to create the basic sounds. Each
Drawbar is marked with the numbers 1 - 8. If you push back the Drawbar until you cannot see any
number at all, the sound of the Drawbar is not heard. If you pull it out to the fullest position The
sound level is maximum.
The pitch of each Drawbar is as shown above, when the middle C is depressed. The footage
marked (') on the handle end of each Drawbar is originated from the length of pipes on a pipe
organ.
The numbers 1 - 8 on the “bar” portion of each Drawbar indicate the volume of the sound to be
produced as well as the guide to remember Drawbar settings.
Pull the fundamental (8'), the third harmonic (2
2
/3') plus the fifth harmonic (1
3
/5') Drawbars out
completely and play the keyboard. Notice how the sound resembles a clarinet.
If you push the 8' Drawbar half-way, you’ll notice the sound becomes more high-pitched and a bit
“harder”. Now pull the 8' drawbar back out fully and push the 2
2
/3' and 1

/5' in halfway. notice how
the sound becomes mellower. Experiment with the Drawbars to obtain your own personal favorite
sounds.
NOTE: You can change the characters of the Drawbars. (P. 72)
