When a bride requested this tune for her attendants' processional, I was delighted to discover it was playable on lever harp, though Antonio Vivaldi composed it for lute and violins. It has three lever changes, requiring a G#, C#, and A# (for lever harps tuned in Eb, play a Bb, instead). Key of D, with many fingerings and a few brackets given.
Don't panic when you see all the black notes! It is actually played slowly, and the left hand accompaniment is very simple. A lovely piece to add to your repertoire.
