Harmonic Analyzer

A software application designed to help jazz pianists transcribe and understand the playing of their favorite musicians, powered by machine learning.


See, hear, and feel every note

Based on groundbreaking research by Bytedance, Harmonic Analyzer uses a machine learning model trained by ingesting over 200 hours of solo piano recordings to accurately transcribe the notes in a piano performance.
