Practice drills

1. Find the changes in C Major

Play only the root on the first beat of each change: C (bar 1, Cmaj7), A (bar 2, Am7), F (bar 3, Fmaj7), G (bar 4, G7), C (bar 5, Cmaj7), A (bar 6, Am7), F (bar 7, Fmaj7), G (bar 8, G7). Keep counting through every bar that holds the same chord; the form resolves back to C.
2. Target the guide tones

When each chord arrives, land on its third and hold it for a beat: E over Cmaj7, C over Am7, A over Fmaj7, B over G7. Then repeat with the seventh (see the table) to hear how the line leads into the next chord.
3. C Mixolydian in position

Play C Mixolydian (C D E F G A Bb) up and down in frets 7–11, one note per beat at 126 BPM. Start and finish on C: 6th string fret 8, or 5th string fret 3 for the next position up.

Guide tones for every chord in the chart
Chord	Root	3rd	7th / 6th
Cmaj7	C	E	B (7)
Am7	A	C	G (b7)
Fmaj7	F	A	E (7)
