Cadenza is designed for advanced high school, college, professional-level instrumentalists to rehearse and perform Western classical music, as well as for private music teachers and conservatory faculty to teach students playing classical music with an ensemble.

On Mac, Cadenza allows you to practice, rehearse and perform with live piano or orchestral accompaniment that follows you in real-time using musical artificial intelligence. Harvesting the computational power of mac, the music artificial intelligence in Cadenza not only understands musical audio and provide live accompaniment, but also learns from your performance and improves over rehearsals like a profession orchestra with a conductor would do.

Cadenza provides an ever-expanding library of 300+ pieces and movements covering the core classical instrumental repertoire. By placing you directly in the center of the musical ensemble, Cadenza helps musicians develop a deeper understanding of repertoire while providing an unparalleled tool for reflective practice.

IMPORTANT: for the best result, please use wired amplified speakers or wired headphones; Cadenza cannot work with Bluetooth speakers or earphones due to Bluetooth audio latency.
