Watch the My Sad Guitar: Rhythm 2 online guitar lesson by Andy Aledort from Jam Night Vol. 3

The initial Am chord is played in a "Jimi Hendrix"-style using "thumbed" root notes on the sixth strig, meaning that ther fret-hand thumb is wrapped over the top of the fretboard to fret the low sixth-string root notes. With the fifth string muted, the ring and index finger are used to fret the rest of the voicing on the higher strings. I use the pinkie for a quick hammer/pull on the G string between the fifth and seventh frets, followed by a straight barre across the fifth fret on the D, G and B strings to sound a C major triad. I then add a single-note line based on the notes of A minior pentatonic--A C D E G--which are the same notes that make up C major pentatonic--C D E G A. The subsequent fourth-position D/F# voicing moves perfectly into the third-position F major voicing after it, at which point I switch to chordal arpeggiations. Over E, I incorporate sliding sixths--pairs of notes that sound a sixth apart, intervallically speaking--based on the E Mixolydian scale: E F# G# A B C# D.
