4.6 CREATING THE SOUND WITH THE DRAWBARS

The harmonic bars or Drawbars allow you to set the basic character of the sound you are
going to use in your performance.
When a Drawbar is pushed right into the organ (i.e. when the numbers on the bar are not
visible) it is deactivated; as it is gradually pulled out, the various volume levels (numbered
from one to eight on the bar) of the harmonic associated to the Drawbar concerned are
set.
Each set of harmonic bars (in our case UPPER on the left and LOWER on the right, as
well as the two central Drawbars for the BASS section) consists of four white Drawbars,
three black ones and two brown. The colour of the Drawbar indicates the type of harmonic,
naturally referred to the tempered scale: white for the fundamental and second, fourth and
eighth harmonics (octave intervals); black for the twelfth, seventeenth and nineteenth
harmonics, and brown for the sub-octave (octave below) of the fundamental and for the
third harmonic.
The OB5 Drawbars are marked with the length in feet of the pipes of the church organs
used to create the notes. The pipe which produced the fundamental was 8 feet long;
shortening its length by half (4 feet) provided a note an octave higher, while doubling its
length provided a sound an octave lower.
