The score follows the song
The playhead moves through the notation as the music plays, which means you can hear what a passage is meant to sound like at the exact moment you are looking at it.
Notation
Sheet music for any song, synced to the recording
Most sheet music is a PDF: correct, silent, and disconnected from the track you are trying to play along with. SheetMuse generates the notation from the recording and keeps it on the same timeline, so the score and the sound stay together.
Pick the format that suits the instrument
The same transcription can be read as standard notation, tablature, a piano roll or a chord chart. A guitarist and a pianist can work from the same song in the format each of them actually reads.
Practise at a tempo you can play
Slow the track down and the notation slows with it. The score does not become useless just because the recording is faster than your hands.
Transpose the notation
Change key and the notation is rewritten to match, so a part written for a range that does not suit you is still readable.
