VGT is an incredible approach to visualizing the 3 scale “sources” needed to improvise “thru” all chord types/ families, in all 12 keys with no more than one fret (or half step ) in either direction . This proven method of over 40 years has changed the way guitarists see the neck , do transpositions, and most importantly improvise over ANY progressions, regardless of difficulty .
A student who has worked thru the VGTGP knows :
how every chord type functions within a key
What scale sources are used to play “thru “ chords
What scales are used to play “over “ chords and chord progressions .
All scales found in Modern Harmony including Hybrids.
Systematic approaches to technique development (alternate picking and Legato), phrasing , comping and much more.
