A series of videos on music harmony, but with a difference, delving into the reasons behind Western music harmony - why we have keys,  why are there major and minor keys, why there are only twelve of each, why we have scales, why do we have seven notes in the major or minor scale, why is there more than one type of minor scale, why do some notes go better together than others, why do some chords go better together than others, why rhythm works . . .. and much more. Suitable for music students of all levels.
