Prepare mode

Exercises from your piece,
not canned lessons.

Most apps hand everyone the same drills. Prepare reads the score you imported and writes a practice set for that piece — the scales in its key, and short drills lifted from its own hardest bars. The warm-up a good teacher would write out, from the music in front of you.

Prepare mode — a practice set built from your piece, on the score with the keyboard below

How Prepare builds it

Reads your piece

It analyses the notes, key signature, recurring patterns and the reach your piece demands — the same MusicXML you practise from.

Finds the hard parts

It scans for scale runs, broken chords and arpeggios, repeated figures, tricky fingerings, chord changes, leaps and dense, fast passages.

Writes the drills

Each becomes a short four-bar loop made from your piece's own notes, with a plain instruction for what to work on.

Drills lifted from the hard parts.

When a bar keeps tripping you up, PianoBrain takes the hardest occurrence and loops it as a four-bar exercise built from those exact notes — not a generic étude. Each one comes with a single, plain instruction, the kind a teacher writes in the margin.

Prepare on — practising a generated exercise from the piece, with fingering on the score and the target key marked on the keyboard

A technique exercise written in the piece's own key — thirds in A-flat major, with fingering above every chord

The technique, in your key.

Alongside the drills, Prepare lays in the fundamentals in your piece’s own key — so the scales and shapes you practise are the ones the music actually uses. Ordered easiest-first, so the warm-up genuinely warms you up.

Fit to your hands.

No exercise stretches wider than the piece itself asks for, and the whole set is ordered by an ergonomic difficulty model — finger transitions, chord spans, awkward thumb-and-pinky moments on the black keys, leaps and speed. The hard things come after the easy ones, on purpose.

Step-by-step key guidance — each row an 88-key keyboard with the next keys and finger numbers marked, for the left or right hand

Inside a prepared set

Real drills, in plain language.

Drills from your piece

Scale fragmentKeep the run even; this supports the passage rather than replacing it.
Broken-chord patternGroup each arpeggio as one shape and keep the wrist relaxed.
Repeated patternUse one fingering and one motion every time the figure returns.
Chord progression mapBlock each harmony first, then play the written movement.
Leaps and octave placementLook before moving; land without searching or tightening.
Speed targetLoop cleanly below tempo, then reach the score tempo without tension.

Technique in your key

Scale — right hand, left hand, hands together (2 octaves)
Scale — contrary motion
Tonic arpeggio — hands together (3 octaves)
Tonic triad inversions
I–IV–V7–I cadence
Thirds & tonic-pedal exercises

HONEST ABOUT HOW IT WORKS

Generated from the notation, not an AI.

Prepare is deterministic. The exercises are derived by analysing your MusicXML — the scales in its key, the patterns in its bars — not written by a language model guessing at your music. Fingering suggestions are the one place a trained model helps, and only when your score doesn’t already specify them. See how a session works ↗
