Craig Denison's research on the testing of pitch discrimination of simultaneous tones is now available in the Journal Research Perspectives in Music Education.
Denison's article described and analyzed his development of a structured test of harmonic discrimination. The test measures a students ability to isolate individual pitches in a chord, known in autism research as disembedding. The test proved to have high reliability and promising validity in isolating cognitive functioning of this musical process.
His article is available in the journal or by request.
