Abstract: A tunable plectrum or pick for guitars and the like, is formed from a suitable material with planar opposed surfaces, an opening extends through the opposed surfaces whereby the skin of the thumb and index fingers of the musician can engage each other to stabilize the pick on the fingers of the musician. The periphery of the opening defines a plurality of angularly spaced inwardly projecting finger engaging material points. The points are sharp enough to pierce the skin of the musician with enough force to further stabilize the pick on the finger. In addition, the periphery of the opening, also defines outwardly projecting tuning openings whose number and shape affects the tune of the pick. Means are provided to modify the shape of the inwardly projecting finger engaging material points, the outwardly projecting tuning openings, and the size of the opening extending through the planar surfaces to tune the pick.
