String Theory

StringTheory is a guitar practice game that turns your own song library into playable challenges. Import supported song files (or use the included songs), pick a part, and play along while the game listens to your instrument in real time with live single-note and chord detection. Your performance is scored as you play..

Built for both learning and replay, StringTheory lets you load your own songs and work on them your way. Use Loop Mode to repeat difficult sections, Note By Note Mode to stop at each note or chord until you hit it, and speed controls to slow songs down while you learn. In addition to real instrument gameplay, the game also includes a rhythm mode for supported chart formats, with keyboard and gamepad support. Whether you want to drill one solo, practice rhythm parts more cleanly, or just play through your favorite charts, StringTheory is designed to make practice faster, clearer, and more fun.
