Watch the Am7 Dm7 F9 E9 online guitar lesson by Robbie Calvo from Sweet Notes
The demo you just heard consisted of me using the A minor pentatonic scale over all of the chords but targeting the chord tones in each of the chords and not just randomly playing phrases. I also added in some chord tones from chord arpeggios that are not in the scale to outline the harmony and I will be showing you this in detail too. Hang in there it's pretty simple really!
Play the Am 7 chord in 5th position and name the notes that make up the chord A C E G. Now play the A minor pentatonic scale shape in 5th position and name the notes. A - C - D - E - G. Notice that the scale shape outlines the chord shape and that four of the five notes are in the chord. These are your "Sweet Notes".
Lick 1 resolves to A, the root note, Lick 2 resolves to C the minor 3rd, Lick 3 resolves to E the 5th and Lick 4 resolves to G, the b7. Let's try resolving to D, the non -chord tone. Do you hear that it is unsettled or unresolved sounding? That's because it's not a "Sweet Notes".
Let's learn and play an Am 7 arpeggio shape in 5th position. The definition of an arpeggio is 'a chord broken into its individual tones'. The arpeggio shape only contains the four notes in our Am 7 chord therefore we don't need to worry about resolving to a bad tone like the D if we want to just use this approach. Are you digging it so far?
