Detection of Key Change in Classical Piano Music
Tonality is an important aspect of musical structure. Detecting key of music is one of the major tasks in tonal analysis and will benefit semantic segmentation of music for indexing and searching. This paper presents an HMM-based approach for segmenting musical signals based on key change and identifying the key of each segment. Classical piano music was used in the experiment. The performance, evaluated by three proposed measures (recall, precision and label accuracy), demonstrates the promise of the method.
