Watch the Improvising over a Jam Track Shape 3 Overview online guitar lesson by Rob Garland from Melodic Soloing: Major Scale
Here we'll be making melodies over a funky maj7 chord progression in the key of C.
The chords for this jam are: Cmaj7-Fmaj7-Am7-Fmaj7-Am7-Fmaj7-Dm7-G7, the tempo is 120 BPM. That's a I-IV-vi-IV-vi-IV-ii-V progression in the key of C, therefore once again all the notes in those chords are diatonic, meaning they are again all from the C major scale. Improvise melodies using C major scale Shape 3.
Phrasing Tip: Shape 3 lays under the fingers well and therefore is a good one to execute faster legato style runs by just picking the first note on each string. If the song has a jazzy funky feel like this one does, try sliding into scale notes from a half step below.
