Cesure is a guitar tab player and editor for iPhone, iPad and the web. Open a tab, play it, slow it down, and correct what is wrong β€” with one account across all your devices. READ Four views of the same score: tablature, standard notation, notation + tab, and piano roll. Open your Guitar Pro (.gp, .gp3, .gp4, .gp5), MIDI, MusicXML and AlphaTex files, or pick a piece from the catalogue of public-domain classical music. PLAY & SLOW DOWN Play any score at the speed you need. Loop a range of measures and name the loop to find it again; the Speed Trainer raises the tempo pass after pass, up to the real one. CORRECT A real editor: several tracks, repeats, two voices, playing techniques. Copy, paste and undo work in all four views, and every save is a version you can go back to. FROM A RECORDING - Chords: get the chord grid of any recording, computed on your device β€” free and unlimited. - Audio to Tab (AI): turn an MP3, WAV or M4A file into an editable tab, transcribed on our servers. A draft to correct, not a finished score. TOOLS - Chromatic tuner - Metronome - BPM detector β€” tap along, or let Cesure listen - Scale cheatsheet - Play together: create a room, share its six-character code, and playback stays in sync for everyone, with voice chat YOUR TABS STAY YOURS Cesure saves in .cesure, an open and documented file format, and exporting it is always free. Share a score with a link, and export it to PDF for free (with a small "Made with Cesure" line). FREE & PRO Reading, playing, editing and every tool are free. Cesure Pro is an optional subscription, with its price shown in the app, that unlocks: - Unlimited AI transcription (3 a month on the free plan) - Unlimited library (3 saved scores on the free plan) - WAV export - PDF without the watermark Cesure Pro is an auto-renewable subscription, monthly or yearly.
