Practice drills

1. Find the changes in Bb Major

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

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

Play Bb Major Pentatonic (Bb C D F G) up and down in frets 5–9, one note per beat at 122 BPM. Start and finish on Bb: 6th string fret 6, or 5th string fret 1 for the next position up.
