While the regular Alto kalimba is not recommended for small hands, this board-mounted Alto kalimba is! Highly capable.
This instrument is played just like the 15-note alto Kalimba, but it lacks the resonant box. Consequently, it sounds even more like an antique music box than does the alto kalimba. The small sound board is well-suited for small hands or children. The small board also permits using the right index finger up-stroke method typically used in mbira playing. A nice trick to increase the volume is to hold it against a window or a table as a sounding board.
