You could look at the collection of 21 traditional, rather than contemporary hymns, that comes with a CD (harp part performed by Danielle Perrett of London)enclosed with all of them in order, played twice. Publisher is Herald Music, title is “Familiar Hymns With a Friend”, and no change of levers are needed once each hymn is started. Arranged my myself, and available from most major harp music dealers in the U.S., Australia, England, and Germany. Solo flute with accompaniment works fine, or if you want to add 2nd flute, viola, and cello, the parts are all there and it will be more full.
