In this mathematical exploration, the students attempts to study the mathematical relationship of notes within chords inn harmony and discordant chords. The gaps in the ratios do not directly relate to the difference in semitones, as the semitones do not have equal frequencies-the frequencies of semitones diverge as the frequencies increase, and the notes get higher in pitch. 1 comment.
