How many notes are there in Happy birthday?
The Happy Birthday piano sheet music arrangement I feature just above uses a simple, bouncy left-hand chord accompaniment in the "Oom-pah,pah" style. I call it simple because it is simple to UNDERSTAND. All the chords are in root position, and there is the seventh chord, as plain as plain, with its 4 notes.
What key is Happy Birthday in?
In the key of E major, the melody to Happy Birthday starts on a B, and when you play a B7, you are playing two Bs: on the A string second fret, and on the open B string.
