Start with a manageable score
For a first session, choose Mary had a little lamb from the practice samples. Its short melody makes the connection between a highlighted note and a key easy to see. To use another piece, browse the catalogue, open its score page and choose Practise this score. You can also bring a scan or open a MusicXML file from the practice starting page.
Listen before you play
Use Play to hear the piece and follow the moving highlight. Notice repeated notes, changes of direction and pauses. For deliberate note matching, stop playback and focus on the highlighted target. Playback is a listening mode; completing a passage by listening does not mean you have played its notes yourself.
Choose one hand when the score supports it
Left selects the lower staff and Right selects the upper staff; Both includes both. These controls work best with clearly separated piano staves. A multi-instrument arrangement may not divide naturally into left and right hands. Check the score itself before assuming a staff belongs to a particular hand.
Match the highlighted notes
Find the highlighted pitch on the on-screen keyboard and tap or click its key. A correct match advances the score. When a chord is the target, match all of its notes; with a MIDI keyboard, play the chord together. If the score does not advance, check the octave as well as the note name: the same letter appears in several places on the keyboard.
Use tempo for listening and accompaniment
Open More to find the playback tempo control. Lower the playback tempo to hear a difficult passage more clearly. The tempo control changes playback and accompaniment; it is not a difficulty rating. During note matching, take time to locate the target rather than rushing to match the original performance speed. Build accuracy before increasing the listening tempo.
Choose how to play
On-screen keys need no instrument or extra permissions. A MIDI keyboard sends note events directly and is useful for repeated practice. Microphone feedback listens to an acoustic instrument and is experimental; background sound, tuning and overlapping notes can affect matching. If feedback becomes frustrating, use the screen keys to check that you have understood the target.
Make room for the notation
Choose More, then Full screen to give the score more space. The keyboard remains available below the notation, and on a small screen you can scroll it sideways to reach other octaves. Keep the current highlighted notes in view and avoid trying to read an entire page at once. In More → Advanced, you can also adjust the keyboard size and note names.
Finish with a short repeatable routine
Listen to a short phrase, work out its notes, then repeat until you can play it with fewer pauses. Restart when you want another attempt. End by playing the phrase away from the visual prompts if possible. Matching notes is useful feedback, but it does not assess every aspect of rhythm, touch, fingering or musical expression.
