consonance and dissonance
Komar views intervals as first dividing into two main categories; those which are absolutely consonant and absolutely dissonant. The absolutely consonant intervals are further divided into three categories consisting of the unison and octave; perfect fifth, major third, and minor third; and major sixth, minor sixth, and perfect fourth. A consonant interval is considered relatively dissonant in relation to another consonant interval if it is located to the right, and relatively consonanant if located to the left of it. Komar uses this formulation for classifying dissonant and consonant suspensions. The six-five suspension is considered dissonant since the sixth is relatively dissonant in relation to the perfect fifth (Komar, 1971).
