[Engineering Reports] The success of polyphonic detection varies depending on the instrument. Different approaches have been proposed. Piano polyphonic detection is particularly difficult. A special approach to detecting piano chords is described. Using a spectral pattern-matching method, chords containing up to four notes have been identified successfully. Chords throughout the complete tonal range (from octave 1 to octave 7) have been tested and identified. Patterns are generated during a training step that uses an acoustical model of a piano.
