I have been asked by our high school orchestra director to accompany a soprano singing the Schubert Ave Maria in Bb. My concern is the auditorium seats about 700 people and without amplification, I don’t think the harp sound will carry well enough. I suggested perhaps harp with strings or other accompaniment. The orchestra director is concerned about an arrangement being too note-y or mushy. The one I heard on youtube that was very pleasant and enhanced the singer was by Andre Rieu. But, it is a proprietary arrangement and not available. Does any one have suggestions for a Bb arrangement? Thank you.
