G major, 4/4 time. “On Valentine’s Day” is a delightful song for Valentine’s Day. With keyboard letters instead of notes on a staff and chord symbols for left hand on piano, guitar or autoharp, it’s perfect for teachers and beginning piano students who don’t read music notation. It also has a keyboard diagram to show where the notes are. It can also be played on a xylophone. The lyrics talk about showing others how much we care about them.
