Most stable pitch classes should occur most often.
Class data cannot be ordered.
Relax requirements of metric space to allow for “distance” between elements of class data.
“Distance” – Based on similarity between two keys.
High similarity corresponds to small distance.
Used methods discussed to correct pitch error
Types of Pitch Error:
Less stable elements are poorly remembered. To compute perceptual pitch error, must have knowledge of the key. The localized key-finding algorithm may be used to obtain this.
