Trapezoid is an American folk music group led by Paul Reisler. Founded in 1975 by Sam Rizzetta and Reisler, they began as a quartet of hammer dulcimer players. Two of the four played the traditional hammer dulcimer, while the other two played baritone and treble hammer dulcimers specially designed by Rizzetta. The name of the band reflects the shape of the hammer dulcimer. Since 1975, the group's membership and instrumentation has changed repeatedly, always with Paul Reisler as a member. Their sound has been described as a "plinking and plunking, buzzing, sweeping, ringing, droning, and wailing acoustic construction" and as "a delightful musical melange" by the New York Times.
In 2004 and 2005, the 1984 lineup that recorded Winter Solstice with John McCutcheon reunited with McCutcheon to perform acoustic concerts, called the Winter Solstice tour. This lineup included fiddler Freyda Epstein, who was killed in 2003 in a car accident bringing the band to a tragic end.
