‘When The Saints Go Marching In” was written in 1896 and is in the public domain. In this video Duane demonstrates how easy it is for beginners — even people who don’t play the piano at all — to play the melody in their right hands with only 5 notes using 5 fingers. In the left hand the only chord that is imperative is the C chord, but more complete if the F and G7 chord are added.
