Hi, I saw your post on here. There is a beautiful choral arrangement I have at home (from the 70's) but still a beautiful piano arrangement and vocals.
Down In the Valley is an old-fashioned song with sweet lyrics and a strong melody. Resting around Middle C & using just 2 chords, it makes a fine duet or solo!
Short aria Nel cor with piano accompaniment in the keys of Eb, F, and G! This pretty little aria is perfect for students just venturing into classical music.
