Fermata

A self-hosted sheet music server. Point it at a folder of sheet music, and get a fast, beautiful library you can browse, search, tag, and practice from — on any device on your network.

Think of it as the music-stand equivalent of Jellyfin or Calibre-Web: your files stay yours, on your hardware, organized the way you already organize them.

Notation / tab / both — MusicXML and Guitar Pro files render interactively and can be switched between standard notation, tablature, or both staves at once, with audio playback, adjustable speed, and a moving cursor. The built-in synthesizer also drives practice tools: drag-select a passage on the score to loop it, plus a count-in. The staff is themed to match the…
