A shaker that carries a tune.
The Shonga by Eccentric Systems Design was designed to be both tunable and melodic. This American-made shonga was turned from solid hardwoods with die-cast chrome hardware and a goatskin head. With this tunable head, Shongas are tuned to a pitch, then with simple finger techniques the player can play or shake melodic notes with a range of over a full octave. Other shakers rattle at a single, random pitch. Shongas add the ability to move the sound in pitched notes, adding much more dynamic range to the instrument.
Eccentric Systems added a guiro to the Shonga shaker to create the Shonga guiro. Now for the first time in history, a guiro can be played melodically. The same simple finger technique is used while playing the guiro to change the pitch multiplying the rhythmic and melodic possibilities with one very versatile little instrument.
