Hi @powel1018yahoo-com the short answer is that Tony’s chord matrix in Fretboard Wiz is a matrix of 3 note chords. So you are correct, the FW chord matrix does not have a G7 chord.

The 7 chords are 4-note chords. (3 is the minimum number of notes you need to have a chord). To make a 7 chord, all you have to do is take the 3 note chord and add a 4th note. So grab any chord from the chord matrix and add one more note to the end of it to get the 7 chord. (You start with the root note and include every other note)

GBD (G-major) becomes GBDF (G7).

CEG (C-major) becomes CEGB (C7)
