Lockhart was first organist of the Lock Hospital, and was for some years associated with Martin Madan in the musical arrangements there. Though blind from infancy, Lockhart had a distinct musical gift, and was especially known for training children’s choirs. His earliest tunes were printed on separate sheets. He published a set of hymn tunes about 1810.
