Color Groups
White Drawbars
The first white Drawbar represents the
"fundamental" or "8' base" tone. All of the other
white Drawbars are octave intervals or harmonics of
the fundamental tone. The tonal brilliance is
greatly increased by adding white Drawbars, but the
harmonics added are always in "consonance" or
harmony.
TRY THIS:
1. Make sure all Drawbars are pushed "In" (off).
2. Press the "B" Preset Key on the Swell Manual.
3. Hold down middle "C" on the Swell Manual.
4. Pull the first white Drawbar in the second group for the Swell Manual, marked 8',
all the way out.
5. Now, one by one, pull the other Swell white Drawbars out in sequence.
As you add each Drawbar, you will hear the addition of the same note an octave higher in each case.
Black Drawbars
The Black Drawbars on the Hammond Organ
represent the dissonant (discordant) harmonics
which are also necessary in building rich tone
colors. The mellowness of a horn, the pungency of
strings, and the brilliance of reed voices owe much
of their character to the presence of these
harmonics in different degrees.
