Frank Simpson plays the Irish tin whistle, an instrument which has been a part of Celtic traditional music from its inception and which has played a significant role in the developing and sustaining of the genre of traditional Irish music throughout its history. Simpson has been playing the tin whistle for 25 years and began as a student of Mary Bergin, a well-recognized Irish master of the instrument. Traditionally part of the music at cruinnithe (gatherings) and festivals, the tin whistle‰’s repertoire is comprised of many regional styles. Simpson has made several recordings in an ongoing effort to document the many tunes that exist but have not been notated.
