Locate F, A, C, D on white keys. Try each hand separately before playing together; choose a fingering that keeps the wrist relaxed, without stretching between notes.
Arpeggio · F6 · Piano
The F6 arpeggio is F – A – C – D — chord tones 1 3 5 6. F6 is a tonic alternative to maj7, especially on the last chord of a tune; its sound is open, classic, swing-era. Below, every F, A, C, D on the two-octave keyboard is marked, with the root in gold. Press play to hear a one-octave arpeggio, or tap any note.

Locate F, A, C, D on white 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: F6 has the colour “open, classic, swing-era”. Name the degrees as you play, so you can recognize the sound in another key rather than remembering only a shape.
Understand the sound
The sixth replaces the major seventh. Compare the softer root-and-sixth relationship with the half-step tension of a major seventh.
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 none. 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.
F6 is a tonic alternative to maj7, especially on the last chord of a tune. Its character is open, classic, swing-era.
F Major (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.
