Locate A on white keys and F♯, C♯, D♯ on black keys. Try each hand separately before playing together; choose a fingering that keeps the wrist relaxed, without stretching between notes.
Play F♯ – A – C♯ – D♯ in quarter notes at 60 bpm. Repeat starting from A, wrapping back to F♯. Do not speed up until every attack is even.
Alternate A and D♯ above a sustained F♯. These are degree ♭3 and 6. End a four-bar phrase on either one instead of always returning to the root.
Listen for this: F♯m6 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 A, and degree 6 is D♯. Play F♯ in the bass and compare these voices individually before combining them.
Try A – C♯ – D♯ – F♯ 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♯, C♯, D♯. Use the groups of two and three black keys to orient yourself. Play F♯ and A with each hand separately before combining the hands.
Before moving on, close the diagram and name the notes: F♯ · A · C♯ · D♯. Then play a two-bar phrase from memory and leave two bars of silence.

F♯ – A – C♯ – D♯. As chord tones: 1 ♭3 5 6. Played one after another instead of together, that is the arpeggio.
F♯m6 is a minor tonic with a Dorian colour, or a rootless 9th of a dominant a fourth below. Its character is minor but bright.
F♯ Melodic minor (F♯ G♯ A B C♯ D♯ E♯) — the arpeggio is the skeleton of that scale, so practise them together.
Play F♯ – A – C♯ – D♯ ascending from F♯, then descend; then start from each chord tone in turn (inversions) so your hand knows the shape from any note.
