Hear the roots
At 60 bpm, first find these chord roots: B, E, A. Then play or sing the root of each sounding chord as you follow the trainer. Keep counting through the whole form. If you lose your place, return to roots before adding notes.
iiø–V–i · A minor
The iiø–V–i in A minor is Bm7♭5 – E7♭9 – Am7. Over Bm7♭5 play Locrian (B C D E F G A); Over E7♭9 play Phrygian dominant (E F G♯ A B C D); Over Am7 play Aeolian (natural minor) (A B C D E F G). A minor is the relative minor of C, so every note here is a white key — the only chromatic note is the G♯ inside E7♭9, and that is the note to listen for.

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.

Your next 10 minutes
At 60 bpm, first find these chord roots: B, E, A. Then play or sing the root of each sounding chord as you follow the trainer. Keep counting through the whole form. If you lose your place, return to roots before adding notes.
Bm7♭5: D and A; E7♭9: G♯ and D; Am7: C and G. Choose one voice and move to the nearest third or seventh in the next chord. Use your ear; not every transition is a half step.
Using the chords Bm7♭5, E7♭9, Am7, use only chord tones for one chorus. On the next chorus add a single passing note between targets. Repeat one rhythmic idea, then leave a full bar of space.
Listen for this: Resolve into Am7 without rushing. Success means keeping the form and hearing your next target, not reaching the highest tempo.
Understand the sound
In a minor cadence, the dominant introduces a raised leading tone that natural minor does not supply. Listen to that note’s pull into the tonic; do not run one unchanging scale across every chord.
| Chord change | One possible line | Movement |
|---|---|---|
| Bm7♭5 → E7♭9 | A → G♯ | Down 1 semitone |
| E7♭9 → Am7 | D → C | Down 2 semitones |
Play the first pitch in each row during its chord, then move to the target as the next chord begins. Choose an octave that allows the indicated movement. Sing the line once before playing it; add the bass roots only after the upper voice feels secure.
Stop playing for one complete cycle while you keep counting. Re-enter on Am7. If you miss the entrance, simplify to roots and work at 60 bpm before adding passing notes.

How to practise this
1. Arpeggios in time. Loop the vamp at 70–90 bpm and play Bm7♭5, E7♭9, Am7 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: D–A → G♯–D → C–G. Notice that D, the 7th of E7, moves to C, the 3rd of Am7 — that is the resolution.
3. Chord-scales. Run Locrian on Bm7♭5, Phrygian dominant on E7♭9, Aeolian (natural minor) on Am7, then improvise keeping chord tones on beats 1 and 3.
4. Move it. When A is clean, go to D minor — a fourth up — and keep going around the circle.

Bm7♭5 – E7♭9 – Am7. The iiø chord is Bm7♭5 (B, D, F, A); The V chord is E7♭9 (E, G♯, B, D); The i chord is Am7 (A, C, E, G).
Bm7♭5: Locrian (B C D E F G A). E7♭9: Phrygian dominant (E F G♯ A B C D). Am7: Aeolian (natural minor) (A B C D E F G).
The thirds and sevenths: D and A over Bm7♭5, G♯ and D over E7♭9, C and G over Am7. Connect each voice to the nearest available third or seventh of the next chord; the distance depends on the progression and voicing.
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.
