Outline Introduction Chord Recognition Harmonic Analysis Application to Musical Sequence Comparison

Chord Recognition http://guitaralliance.com/chord_phrasing.htm The Algorithm Surface Segmentation Chord Identification Chord Merging

Chord Recognition Continued … Recognition is performed with template data base search Path recognition of distances between notes - Example Cmaj 7th 4-3-4

Chord Recognition Continued … Two rules of chord merging Equal roots Bass note carries over

Harmonic Analysis Roman numerical analysis of all chords Preferences imposed For example:

Application to Musical Comparison Similarity on musical sequences Features defined: Absolute Pitch Absolute Duration Pitch Contour Duration Contour Metric position Tonality Harmony
