|Abstract||Cq-profiles are 12-dimensional vectors, each component referring to a pitch class. They can be employed to represent keys. Cq-profiles are calculated with the constant Q filter bank. They have the following advantages: (i) They correspond to probe tone ratings. (ii) Calculation is possible in real-time. (iii) Stability is obtained with respect to sound quality. (iv) They are transposable. By using the cq-profile technique as a simple auditory model in combination with the SOM an arrangement of keys emerges, that resembles results from psychological experiments, and from music theory. Cq-profiles are reliably applied to modulation tracking by introducing a special distance measure.
