What is the meaning of single, double, triple, quadruple reed?
This simply indicates the number of reeds that sound simultaneously in the right hand when depressing one button. The left hand is not so straightforward however. Doubles usually have two reeds on each side. Triples and quads will often have one less reed on the left than the right (so that the accompaniment doesn’t overpower the melody.) A triple with three reeds on both sides is often called a “full triple.” Also, many instruments have an extra set of extra low reeds for left hand buttons 1, 5 & 10. These are usually called “contra bass.” Single reed is extremely rare, and is usually enocuntered only on old instruments, or other types of concertinas. Adding more reeds does several things: • Adding reeds in unison increases volume. • Adding reeds tuned an octave above or below the first set will create a fuller, brighter sound. • Adding reeds in unison that are slightly out of tune adds tremolo or “wave.” to the sound.
