Susan Matsui was born Berkeley, California. She began composing as a child. She plays French horn, piano, and organ, and many medieval and folk instruments, both string and wind. She studied composition at Williams College with Dan Gutwein and at the Salzburg Mozarteum with Cesar Bresgan.
She is the organist and music director at the Second Congregational Church of Williamstown, MA, and a member of AGO. She is also a public school music teacher and a member of Woodbinde Medieval Band. She is continually composing and arranging music for use in her church, for both the adult and junior choirs. Her music is influenced by her nearly twenty years in Japan, as well as by medieval music, and by her formative years in an Episcopal church with an outstanding music program and organist (Grace Episcopal Church in Nyack, NY).
She has published 35 children’s books, among which are three songbooks, and she continues to publish children’s songs in monthly children’s magazines in Japan.
