This technical article details the development of a real-time chord recognition system that moves beyond simple dictionary lookups to implement a sophisticated scoring model. The system processes musical input through a four-stage pipeline that handles pitch-class bitmasking, candidate generation, score normalization, and ranking to accurately identify chords even with missing or extended notes. The approach addresses key challenges in music information retrieval by incorporating musical context and heuristics to resolve ambiguities in chord identification.
Background
Chord recognition is a fundamental challenge in music information retrieval, with applications in music transcription, education, and performance analysis. Traditional approaches using fixed dictionaries struggle with the complexity of real-world music where notes may be omitted or extended beyond basic triads.
