Cass-good symplified explanation of the viability of only three diminished chords in this video. Just memorize the 4 notes in each chord. As inversions, that particular fingering is 4 different diminished chords. All you have to do (simplified way) is to make sure that the structure you use has the root note, or bass note of the chord you're after. With guitar, it's easy, too. Just have your first finger touch the appropriate note on the high E, or your 2nd finger touch the correct "C" position on the 2nd or "B" string. It's pretty easy. The selection of the position has to do with the tune structure and proximity of the other chords and lead line notes of the tune.


Fun stuff!
