J.S. Bach's Original Hymn-Tunes for Congregational Use. (Facsimile 1922).

Charles Sanford Terry (1864-1936), Historian and Bach Scholar.
He studied at St. Pauls Cathedral Choir School as a solo boy, King's College and Lancing. He studied history at Cambridge and lectured in history at Durham College of Science and at Aberdeen. He spent much of his life devoted to Music and to Bach in particular. He started choral societies in both Newcastle and Durham. He wrote extensively on Bach. Walter Emery said that his biography of Bach was "the only one that is both detailed and readable". I have a theory that it is easier to read books by musicians who were trained in English or history.
