Solfimi

Piano · engraved score · your own tempo

The score that
follows you.

Play at your own tempo, without taking your hands off the keys. Solfimi follows you on genuinely engraved sheet music and prepares what comes next a beat ahead: nothing scrolls. At the final note, the bars that resist are circled in pencil. Practise one hand: it plays the other. On a digital piano, or through the mic on an acoustic one.

IAdagio sostenuto

A phone on the music stand.
Just play.

Found a piano far from your scores? Stand your phone on its music desk: the microphone listens for your attacks, Solfimi finds the bar and shows the next one before you reach it. Go back four bars: it meets you there.

  • Listened to on the device

    The sound is analysed where it is heard, never recorded or sent: only the recognised notes are kept.

  • To the bar

    Your current bar, the next one already prepared, your practice loops at hand — and a discreet indicator that pulses with every attack it hears.

Real Solfimi screenshots on a phone, listening to a piano recording through the microphone: Beethoven, Op. 27 No. 2, bars 1 to 8.

IIDa capo

Progress
at your own pace.

On a digital piano, Solfimi hears everything: the note, the moment, the touch, the pedal. Learning? Between lessons, it keeps your teacher’s playing and accompanies you with it. Already playing? Record one hand as you hear it: Solfimi plays it back while you practise the other.

Sonata facile Wolfgang Amadeus Mozart · k. 545
  1. i

    The report, in pencil

    Bar by bar: wrong notes, hesitations, stops, a hand that lags, and the broken slur, the forgotten dynamic, the key-signature accidental that slips by. The passage that fights back is circled on the score, as your teacher would, and the mark fades as it improves, from one session to the next.

  2. ii

    The loop

    One gesture, and the passage loops: Solfimi brings you back to its start every time. Three clean passes in a row, and it is in place. To find a passage again, put a bookmark on it: one tap takes you back, or two presses of the pedal without leaving the keys.

  3. iii

    A metronome that listens

    It beats the written metre, but at your tempo: a little ahead when you slow down, it lets itself be caught when the new tempo lasts. A partner, not a judge.

IIIModerato

Play one hand.
Solfimi plays the other.

Practising the left hand on a digital piano? Solfimi plays the right on the Solfimi Grand Piano, at your tempo: it takes it from your first notes, follows you when you slow down or press on, falls silent when you stop and starts again with you. You hear the whole piece long before you can play both hands together.

  • With its dynamics

    The other hand is not played flat: Solfimi follows the written dynamics, lets the melody sing, holds or detaches notes as the score asks.

  • As it was played to you

    Your teacher plays one hand, once, on your piano: Solfimi plays it back with their dynamics while you practise the other, and can take their tempo, breathing included. You practise alone, their playing in your ear.

  • The pedal stays yours

    Your digital piano’s pedal holds the notes it plays too.

  • In your loops

    In a loop, it accompanies only the passage you are working on.

Elegy Sergei Rachmaninoff · op. 3 no. 1
Rachmaninoff, Elegy op. 3 no. 1, bars 1 to 9. The left hand, its arpeggios, is played by the pianist; the right hand, the melody, by Solfimi’s own accompaniment. The sound is generated by the built-in Solfimi Grand Piano model.

IVCantabile

It reads music
the way you do.

Solfimi reads an engraved score, not a frozen picture: every note is a living sign it can light, circle, transpose. It knows the two staves, the two hands, the chord, the ornament.

Instrumentation

On a digital piano
A digital piano or a MIDI keyboard, connected by USB to a computer (Chrome, Edge or Firefox) or an Android tablet (Chrome). All of Solfimi: the finest following, the report, the pencil, the loops, the other hand played for you.
Through the microphone
An acoustic piano, and on its music desk a phone, a tablet or a computer. The essentials of Solfimi from sound alone: following to the bar, what comes next shown ahead, and work in loops.
Ad libitum
No piano at hand? The computer keyboard is enough to try it out.
Solfimi Grand Piano

A MIDI keyboard without speakers, or the computer keyboard? Solfimi sounds them with its own piano: a model of a grand piano, measured on recordings of a real one and computed in real time on your device.

On iPhone and iPad (where browsers do not yet support connecting MIDI), Solfimi simply listens to your piano through the microphone.
