A Turritella Terebra seashell made into a musical wind instrument (flute) with five pitch holes.
Each unique shell contains an octave and a half of diatonic notes, which is more than enough to play a wide variety of music.
The seashell flute was discovered, developed and crafted in 2003 by Michael Ryan, a musician with over fifty years of experience playing wind, string and percussion instruments.
Seashell flutes are available in the keys of B, C and D, which correspond to player’s hand size. B is for men with big hands; D is for women with average to small hands; C is for men with average size hands and women with slightly larger than average size hands.
The Screw Shell Flute is recommended for players ten through adult.
