Keyed Pentacorders with 4 keys are designed to be played with only one hand. Either the left or the right hand can be used. The other hand can play a drum, a hurdy-gurdy drone, or other rhythm instrument at the same time.
People unable to use both hands for playing a musical instrument will find it very enjoyable to play a 4-keyed Pentacorder with only one hand.
Unlike a Tabor-Pipe which starts its scale with the first harmonic, the sound of a Pentacorder starts with the fundamental, the lowest note!
Currently we make 4-keyed Pentacorders with a lowest note of -G- and -A-. (see the chart above)
A two-hands, open tone-holes version and a one-hand version with four keys are shown on the right.
