I'm taking a few lessons again and my teacher. the other day he was showing me how to play six chords over a major chord (if I'm expressing this right). For example, in bluegrass stomp, on the D he was moving from D to D6 to D7 before the shift to G. And showed me that the minor 6 chord works--for D, you can play Bminor, it's the same as a D6 (only missing one note). Well, it sounded good when he did it but not so good when I tried in the jam yesterday. Does anyone use this? Any advice about fingerings that work better? I certainly like the idea of making my rhythm playing more interesting, esp as there is usually at least one other mando player.
