Dave began classical piano study at the age of five and trombone at age ten, playing in school, college, and community bands. His interest turned towards jazz and blues in college while also studying music theory and playing in a jazz and rock group. His piano playing continued as accompanist for family vocal performances, teacher, and frequent composer. When MIDI was introduced in 1983, allowing the connection of computers and music equipment, Dave was a partner in a chain of computer stores. At that time, he assembled his first home electronic music studio to support consulting, training, and producing commercials, videos, and developing and teaching a university course. He also led workshops at many public schools and colleges, as well as, teaching electronic music at the PA Governor's School. Since 2015, after retiring as Chief Information Officer at Lycoming College for twenty years and as an electronic music consultant, Dave is now focusing on composing and producing music in his Pro Tools studio. His music is available through his website: daveheffner.com and through most streaming services. He is an ASCAP member.
