Find F♯ on the keyboard

F♯ is the left black key in a group of three black keys.

For this root-position chord, the highlighted keys are F♯, A♯, C♯. White keys: 0. Black keys: 3. Start with F♯ as the lowest note.

Why these notes belong together

From F♯, move up four semitones to A♯, then three more to C♯. This makes a major third and a perfect fifth above the root: F♯, A♯, C♯.

One semitone is the move to the very next piano key, white or black. Count each move, rather than counting your starting key.

One small exercise to start with

1. Find and play F♯ on its own.
2. Play F♯, A♯, C♯ slowly, one note at a time, then together. Let your hand stay relaxed.
3. Lift your hand, find F♯ again and rebuild the chord. Aim to find the notes comfortably before adding speed.

Try the same chord in a new order

Move the lowest F♯ up one octave. The notes become A♯, C♯, F♯, with A♯ at the bottom. This is first inversion: the chord still contains the same notes, in a different order. Try it after the starting position feels familiar.

Tell F♯ major apart from nearby chords
