Map it slowly
Locate B, E♯ on white keys and F♯, G♯, A♯, C♯, D♯ on black keys. Try each hand separately before playing together; choose a fingering that keeps the wrist relaxed, without stretching between notes.

F♯ Major (Ionian) scale on piano
The F♯ Major scale is F♯ G♯ A♯ B C♯ D♯ E♯ — formula 1 2 3 4 5 6 7, step pattern W–W–H–W–W–W–H. Use it over F♯maj7: it is the scale for the I chord (maj7) and any major-key tonic; the default over Imaj7 in a ii–V–I. Below, every note is marked on the two-octave keyboard; press play to hear it on a synthesized piano while each note lights up, or tap any key to sound that note.

Make a short phrase
Play F♯ – G♯ – A♯ as two eighth notes and a quarter note, then rest for two beats. Answer with E♯ – D♯ – C♯. Use the space to hear the phrase before repeating it.
Hear it in context
Hold or repeat F♯ as a drone. Play each note of F♯ Major above it, pausing on G♯ and E♯. Compare their tension with the root. Then improvise using only three notes and two rhythms.
Listen for this: the I chord (maj7) and any major-key tonic; the default over Imaj7 in a ii–V–I. Treat the scale as a palette, not a requirement to play every note. If a note clashes with a chord or melody, resolve it deliberately or leave it out.
Understand the sound
F♯ Major: from a pattern to a musical choice
Hear B in context
The fourth can rub against the major third in a sustained major-seventh voicing. Hear that tension before deciding whether to hold it or move on.
In F♯ Major, degree 4 is B. Play F♯, then B, then F♯ again. Sing the middle note before touching the instrument.
A mistake to avoid
Treat a scale run as raw material. Break it into a short question and an answer.
Slow the player to 60 bpm. Record one short phrase and check whether its ending sounds deliberate. Increase the tempo only when you can repeat it without losing the pulse.
F♯ Major versus G♭ Lydian
Shared pitches: F♯, G♯, A♯, C♯, D♯, E♯. Pitches in F♯ Major outside the comparison scale: B. Compare the sounds over the same root, at the same tempo.

The black-key pitches in this collection are F♯, G♯, A♯, C♯, D♯. Use the groups of two and three black keys to orient yourself. Play F♯ and G♯ with each hand separately before combining the hands.
Before moving on, close the diagram and name the notes: F♯ · G♯ · A♯ · B · C♯ · D♯ · E♯. Then play a two-bar phrase from memory and leave two bars of silence.
