keystrum

keystrum is a free, open-source browser-based virtual guitar that maps QWERTY keyboard rows to four strings and columns to six diatonic chords. It utilizes Web Audio API and Karplus-Strong physical-modeling synthesis to provide real-time strum detection and authentic plucked-string audio without requiring software installation or accounts. The platform serves musicians, educators, and producers by enabling chord progression practice, recording, and sharing directly within the web browser.
