For many years now, I have been using the kamalengoni with adults with disabilities.
That instrument is adapted to musical exploration with that kind of audience because of its reassuring shape and the “color” of its sounds.
The pentatonic scale of the instrument, which means that all notes can chime well together, facilitates the momentum of going inward, brought about by the sounds of the instrument.
That instrument has the peculiar ability to bring on a feeling of security due to its scale and appeasing sounds. It allows anyone, musicians and especially non musicians, to feel the joy of playing an instrument.
