Practice drills

1. Find the changes in Eb Major

Play only the root on the first beat of each change: Eb (bar 1, Ebmaj7), C (bar 2, Cm7), Ab (bar 3, Abmaj7), Bb (bar 4, Bb7), Eb (bar 5, Ebmaj7), C (bar 6, Cm7), Ab (bar 7, Abmaj7), Bb (bar 8, Bb7). Keep counting through every bar that holds the same chord; the form resolves back to Eb.
2. Target the guide tones

When each chord arrives, land on its third and hold it for a beat: G over Ebmaj7, Eb over Cm7, C over Abmaj7, D over Bb7. Then repeat with the seventh (see the table) to hear how the line leads into the next chord.
3. Eb Mixolydian in position

Play Eb Mixolydian (Eb F G Ab Bb C Db) up and down in frets 10–14, one note per beat at 126 BPM. Start and finish on Eb: 6th string fret 11, or 5th string fret 6 for the next position up.

Guide tones for every chord in the chart
Chord	Root	3rd	7th / 6th
Ebmaj7	Eb	G	D (7)
Cm7	C	Eb	Bb (b7)
