Alan Hovhaness (1911- 2000) was an American composer. He was one of the most prolific 20th-century composers, with his official catalog comprising 67 numbered symphonies and 434 opus numbers.However, the true tally is well over 500 surviving works since many opus numbers comprise two or more distinct works.
The Boston Globe music critic Richard Buell wrote: "Although he has been stereotyped as a self-consciously Armenian composer, his output assimilates the music of many cultures. What may be most American about all of it is the way it turns its materials into a kind of exoticism. The atmosphere is hushed, reverential, mystical, nostalgic.
The popular Prayer of Saint Gregory (1946), whose lyrical trumpet line is intoned over rich string chords, is a prime example of the simple nobility and affirmation of faith found in much of his music. The work has received thousands of performances, and has been recorded by a number trumpeters, including Wynton Marsalis. The organ transcription was written by Lo Muscio on 2006.
