Click any chord card to see its scale, and tap any key or fret to hear that note. Turn on “+ Arpeggios” or “+ Scales” and the guitar or piano plays the line live over the vamp, lighting each note on the diagram as it sounds.

Build the G major turnaround into your ear.

1. Arpeggios in time. Loop the vamp at 70–90 bpm and play G△7, Em7, Am7, D7 as 1–3–5–7 quarter notes, one chord per bar. Use the “+ Arpeggios” loop above to hear it played and copy the line.

2. Guide tones. Play only the 3rd and 7th of each chord: B–F♯ → G–D → C–G → F♯–C. Notice that C, the 7th of D7, falls a half-step to B, the 3rd of G△7 — that is the resolution.

3. Chord-scales. Run Ionian (major) on G△7, Aeolian on Em7, Dorian on Am7, Mixolydian on D7, then improvise keeping chord tones on beats 1 and 3.

4. Move it. When G is clean, go to C major — a fourth up — and keep going around the circle.

What is the guide-tone line for the I–vi–ii–V in G major?

The thirds and sevenths: B and F♯ over G△7, G and D over Em7, C and G over Am7, F♯ and C over D7. Each voice moves by a half-step or stays put — that is what makes the progression sound like it resolves.

How should I practise this progression?

Loop the vamp at a slow tempo, play each arpeggio 1–3–5–7 in time, then play each chord-scale up and down, then improvise using only chord tones on the strong beats. When it is clean, move to the next key around the circle of fourths.
