FretStudio turns music into a language you can actually speak. Notes are the letters. Chords are the words. Progressions and melodies are your sentences. And songs are the stories you tell. FretStudio is one place to learn that language, practice it, and perform it. LEARN Structured tracks take you from your first note to full songs — built for real beginners, including short fingers and the barre-chord wall we all hit. Clear, step-by-step, no theory dumped on you before you need it. PLAY A practice studio built for progress: load any song, sync a backing track, slow the tempo without changing pitch, loop a tricky section, and watch the chord chart scroll in time. Automatic key and tempo detection does the setup for you. PERFORM Everything you need on stage. Build setlists, run a distraction-free teleprompter that scrolls with the music, rehearse a song, then take the whole set live. BRING YOUR OWN SONGS Import from ChordPro, OnSong, plain text, and more. Your library syncs to your own Dropbox or Google Drive, so your songs are yours and follow you everywhere.
