Diatonic scales is a way of playing scales with 4 sounds chords.
GuitarTools helps you finding out Chords positions among 6 inversions with the 4 sounds.
Some inversions are not playable for a normal human being... Although, Tommy might be able, but is he a real human guitar player
Anyway, I find them quite useful to try some unusual voicing or sounds combinations.
THe picture bellow shows the very classic G diatonic scale on the bottom strings. The chords are : G7M, Am7, Bm7, C7M, D7, Em7 and F#m7b5.
Each chord matches the color degree. So, in this example, the GM7 is in red, and the D7 in yellow. You can change colors by clicking on the degrees grid.
The rest of us should try to play the chords scales with the easiest voicing, that means when you don't have to stretch your hand to far ! In this panel, the color will match the entire chord to play while respecting the degree of the chord.
You can also choose among 6 fingerings by clicking on the little diagrams. This gives you plenty of combinations to try.
