Truelove was born in Hobart, Oklahoma, and studied composition at the University of Tulsa, where he received an M.M. in 1970. He attended the Naropa Institute in 1974 and 1975, and the Darmstadt Internationale Ferienkurse für Neue Musik in 1982 where he participated in Herbert Henck’s piano master class. In 1984 he completed a DMA in piano performance at the University of Oklahoma, with a dissertation on Karlheinz Stockhausen's Klavierstück XI, a score whose sketches he had researched in the composer’s archive in 1980 (Truelove 1998, 190).
His compositions include music for solo and duo piano, orchestra, song cycles, choral music, chamber music, music for ballet, music for film, electronic and computer music, improvisational scores, and a mixed-media chamber opera, Flowers and Butterflies. A work for soprano, narrator, clarinet, piano, and mixed media, Father Sun/Mother Earth, was extracted from the chamber opera in 1993 (Druhan 2003, 22 & 119).
He won First Prize The New Music Forum of Houston Composition Competition 1986, and a Silver Medal in the 1983 International Piano Recording Competition. Truelove has taught piano and composition at Southern Oregon University.
