Keyboard style percussion "BARcussion" is a series of percussion instruments that make sounds just by pressing the keys with your fingers. Since it can be played with one finger, it is possible for one person to sound multiple BARcussions at the same time. As an instrument that can be easily enjoyed at the table, it can be used in a wide range of situations, from small acoustic bands, home studio use, music therapy to educational music scenes. 'Shaker Drum' is the sound of a small shaker.
