Morton often played the melody of a tune with his right thumb, while sounding a harmony above these notes with the fingers of the right hand. This could add a rustic or “out-of-tune” sound due to the playing of a diminished 5th above the melody. This technique may still be recognized as belonging to New Orleans. Morton also walked in major and minor sixths in the bass, instead of tenths or octaves. He played basic swing rhythms with both the left and the right hand.
