Locate A, C, E on white keys and F♯ on black keys. Try each hand separately before playing together; choose a fingering that keeps the wrist relaxed, without stretching between notes.
Play A – C – E – F♯ in quarter notes at 60 bpm. Repeat starting from C, wrapping back to A. Do not speed up until every attack is even.
Alternate C and F♯ above a sustained A. These are degree ♭3 and 6. End a four-bar phrase on either one instead of always returning to the root.
Listen for this: Am6 has the colour “minor but bright”. Name the degrees as you play, so you can recognize the sound in another key rather than remembering only a shape.
Understand the sound
This chord has a minor third and a natural sixth. The sixth is not a flat sixth; compare those notes over the same minor triad.
Here the third is C, and degree 6 is F♯. Play A in the bass and compare these voices individually before combining them.
Try C – E – F♯ – A as quarter notes, then repeat the first note and omit the last. The second phrase uses the same harmony with a different shape.
Separate the bass from the upper notes. If the low register sounds muddy, move the upper voices up an octave before adding more notes.
The black-key pitches in this collection are F♯. Use the groups of two and three black keys to orient yourself. Play A and C with each hand separately before combining the hands.
Before moving on, close the diagram and name the notes: A · C · E · F♯. Then play a two-bar phrase from memory and leave two bars of silence.

A – C – E – F♯. As chord tones: 1 ♭3 5 6. Played one after another instead of together, that is the arpeggio.
Am6 is a minor tonic with a Dorian colour, or a rootless 9th of a dominant a fourth below. Its character is minor but bright.
A Melodic minor (A B C D E F♯ G♯) — the arpeggio is the skeleton of that scale, so practise them together.
Play A – C – E – F♯ ascending from A, then descend; then start from each chord tone in turn (inversions) so your hand knows the shape from any note.
