Block Chords/Drop 2 Tip
I'm sure many of you know this ...
When I learned block chords, I was told that if the melody note is in the chord, you play the notes of the chord. If not, you play the diminished chord that includes that note.
But I recently learned that it will always be the same diminished chord. For example, for a C6, it will always be the F dim chord. I also find it easier to think "Am7" instead of "C6" for the chord tones. So, playing a scale you'll just be playing Am7, Fdim, Am7, Fdim, etc.
For me, that reduces the amount of thinking I need to do when playing block or drop 2 chords. At least until the muscle memory kicks.
