  1. Your diagram shows six fingers on the right hand. Of course, when played with a C in the bass, you won’t need the c in the treble. Perhaps a discussion of chords in root position and then in inversions might also be a helpful addition to be read before getting into the individual chords.

    1. Sure! You’re right, especially in this case, it would be helpful adding some extra info. I’ve added 6 notes on the keyboard to show intervals but it may result confusing. Thank you for your suggestion!
