| contents | The determination of musical key is a fundamental aspect of music theory and perception, providing a harmonic context for melodies and chord progressions. Automating this process, known as automatic key detection, is a significant task in the field of Music Information Retrieval (MIR). This article outlines an algorithmic methodology for estimating the musical key of an audio recording by analyzing its tonal content through digital signal processing techniques and comparison with theoretical key profiles. |
