William Ghezzi has performed extensively with orchestras, chamber ensembles, choruses, dance companies, theater, opera, film, radio, and television. He has appeared with the Montpelier Chamber Orchestra, the Harry Partch Ensemble, the Philadelphia Guitar Ensemble, and in many other solo and collaborative settings. His recordings are available on Spotify, iTunes, Amazon, and YouTube Music, and his performance videos can be seen on YouTube, Vimeo, and Instagram. His most recent release, Telemann: Fantasias for Viola da Gamba, is available on all major streaming platforms.

Guitar Chamber Music Press​ has recently published Ghezzi’s transcriptions of ​Five Fantasias for Viola da Gamba by Georg Philipp Telemann. This project—encompassing transcription, recording, and performance—reflects his longstanding interest in adapting early works for the guitar. The physical similarities and shared ancestry of the guitar and viola da gamba make these Fantasias particularly compelling candidates for transcription.

Ghezzi has also commissioned numerous works for solo guitar and chamber ensembles, including collaborations with the Newman/Ghezzi Guitar Duo, the Baxter/Ghezzi Flute & Guitar Duo, and the Philadelphia Guitar Ensemble. Composers who have written for him include Robert Maggio, Laurie MacGregor, Kile Smith, Robert Capanna, Paul A. Epstein, and Jan Krzywicki.

He holds a music degree from Temple University’s College of Music, where he studied with Peter Segal and Anna Kotsarenko. He pursued further private studies with Phillip de Fremery, Eliot Fisk, and Vladimir Mikulka. Ghezzi has served on the faculties of Temple University, Chestnut Hill College, and Settlement Music School in Philadelphia. He now resides in West Lebanon, New Hampshire, where he offers private instruction at all levels.
