Purcell may have been composing already when he was nine. We know that he wrote an ode for the King's birthday in 1670. When Humfrey died Purcell studied with the famous composer John Blow. He went to Westminster School. In 1676 he was made organist at Westminster Abbey. He started writing music for the theatre. He also wrote church music, including an anthem for a singer called John Gostling who had a very good, deep bass voice. Purcell wrote several anthems for him during his life. One is called "They that go down to the sea in ships". It goes down to a low D.
