About

Sheet! is a focused practice studio that pairs sheet music (MuseScore, IMSLP, Songsterr, 8notes) with a YouTube backing track on a single screen. A unified search bar drives both panes at once, so a single query lands you on a score and a play-along video together. Save your favourite pairings as named presets to revisit later, and capture audio takes from the Recording tab to hear how you played.
