Introduction

A statistical approach to music theory

The presence of chromatic materials in music is inversely proportional to the difficulty in explaining them. The bulk of harmonic areas found in Common Practice Period music (a hypothetical 85%) will be tonics, dominances, connections, and substitutions. Most of the remaining areas will be tonicizations and modulations (a hypothetical 10%). The remaining 5% will be the exotic chromaticism described in this unit (and the next). These chords are interesting and appealing, but must be kept in perspective in regards to their importance.
