Let's start jamming Perry Como - Oh Marie chords, Practice these chords sequence - Bbm, Eb, Ab, Bbm, G, E, Bbm, Cm, D and Gm. I suggest starting at a calm pace of 65 BPM, and as you gain confidence, approach the song's BPM of 131. For a balanced pitch, adjust the capo with respect to your voice and the song's key: G Minor.
