What's a bodhrán applique?
An
applique in this example is something that is attached to a drum skin to affect
the way in which it vibrates. Although it's still relatively uncommon, there are
three main types of applique used.
- Band of
tape
- Weight
- Double skin
A
band of tape is affixed to the drum skin where it crosses the bearing
edge. The purpose of the tape is to provide a mass, a shock absorber, that can
absorb many of the extra overtones leaving just the main ones and the
fundamental. The idea comes from the Indian Tabla drum.
The
weight or centre patch is again derived from the Indian tabla drum. Its
purpose is to affect the main mode of vibration of the drum so that the skin
moves in a particular way that generates a pure tone.
.
The
double skin bodhrán is one offered by several makers. In this two skins
are placed on the drum to provide a full bassy sound. I have not seen or played
one but the opinions that I have heard and the anecdotes offered have been mixed
in their support.
