The Shared Source of Irregular Rhythms and Dissonant Intervals!

This is the fifth, penultimate, video in a series that discusses the acoustical foundations of all musical parameters and how this has guided musical development since the Middle Ages.
In the previous video, we explored the idea that pitch and rhythm are not just related but are fundamentally the same thing! Here we investigate how this applies to the higher frequency ratios of the harmonic series and how even the most complex irregular rhythms can be derived from the same ratios that create dissonant intervals!
We trace this with reference to composers who are notable for their contributions to rhythmic devilment in the 20th Century including Igor Stravinsky, Olivier Messiaen, Henry Cowell and Conlon Nancarrow.

I'm quite enthrilled to have discovered your channel by chance from my curiosity. Trying to use this for my accordion and future structuring is going to be fun and helpful. Can't wait for the next episode.

A very interesting and informative series. Thank you. I am surprised you did not mention, even if only in passing, embodiment as a potential factor in the unequal influence of timbre on melody/harmony versus rhythm. Put simply, can you dance to it? 😀 You had considered embodiment (though without explicitly noting it) when you considered the influence of the range of men's and boys' voices in the development of harmony from plainsong. My inexpert take on it (as a mere bass player😁) is that in 'music' the influence of the naturally occurring ratios in regular materials (strings, tubes, etc.) confronts, and is tempered by, the logistics of the human body: in melody/harmony e.g. the human audible range etc, and in rhythm to what extent can you 'shake a tail feather' - tap a foot or hand, nod a head, bounce from one leg to the other, swing your arms, etc. The music that is so 'unplayable' by humans that it has to be produced by machines, is also going to be very difficult to relate to bodily. That's not to say there shouldn't be music that you can't dance to, but that it will be experienced as something in opposition to that which one can have an obvious bodily response to. I say the above in the spirit of discussion, rather than as a criticism. I've found it a very illuminating and thought provoking series. Thank you.

A really excellent exploration of a fiendishly complex concept. I loved the revelation of the palindromic nature of tonal relations as rhythm.

Thanks very much. I'm really pleased you found it interesting.

This series is wonderful! Is one more video coming?

Thank you very much! Yes, one more on the way - just not sure when!

This series was fascinating and everything that I was looking for when my curiosity piqued about sound and harmony, and more! I have a question for you. In this series you have discussed harmony and rhythm and how they relate to natural overtones, but do you think that melody can be addressed with the same sort of mathematical approach? If physics is responsible for the origin of harmony and rhythm, what about melody? I'm curious about your thoughts. Thank you!
