Metric Modulation, Tempo Calculating & Coordinate Systems

Metric modulation has become a trend in contemporary drumming. In this video I explore the its principles and describe how the same set of sounds can be interpreted from the notation perspective. The piece I play is Study 17 from Gary Chaffee's Rhythm & Meter Patterns.

I always struggle to know how to count the odd 16ths Is 5:4 - 1,e,and,ah,gah? Are Sextuplets - 1,e,and,ah,gah,dah? Is 7:4 - ? How do you count 5:4 and 7:4 sixteenth notes and a group of 6 sixteenth notes, just curious?

[@YaroslavKurilo]

For 5:4 I would use either “one-two-three-four-five” or “cha-ka-tu-tu-tu” or anything similar. But honestly, I don’t count that much. As for the 5’s, 6’s and 7’s I’m more used to the several stickings which give a certain feel of the figure. Like, with 5’s its either RLLRR LRRLL or RLRLL / LRLRR

Nice video and the execution is really clean. I think it's easier to understand if you just use fractions rather than some decimal expansion. Also, it's not 1.33334. It's 1.33333. When you try convert to the new coordinate system, around 5:36, I was hoping you would get to the idea of notating it cleanly as a nested tuplet rather this "every 4th quintuplet" notation that is much harder to read in my opinion. You can still convey the same idea of squeezing 5 notes into 4 (but just in terms of triplets). I feel you though in terms of bailing when the prospect of an irrational time signature.

Thanks Fred! You're absolutely right about the decimal thing. A lot has changed in my perception of modualtion and related things over the year. I had to deal several times with interpreting the score where it would be easier to switch to another tempo than to keep in mind the trick with complex tuplets. Anyway, it's weird stuff and I like the weird stuff, haha.

beautiful

Thanks for this lesson!!!! 🙌🙌🙏🏼🙏🏼

This is really interesting. I have a question, I don't know almost nothing about music so this may sound obvious. What does the last number mean? If you show, for example, 5:4, does that mean there are 5 notes where there used to be 4?

[@YaroslavKurilo]

Exactly! Generally if there is a group of 5 16th notes with 5:4 above, it means you need to fit 5 notes instead of usual 4 16ths. Same, for instance, with 7:4 above 8th notes - you fit 7 notes instead of 4 8th notes. A lot of guys write only the first number which sometimes can be a bit confusing, and I find “x:y” to be more convenient.

@@YaroslavKurilo thank you so much!

broo i forgot this guy,, yaroslav was the shtttt back in 2020 hope u doin well these days

[@YaroslavKurilo]

Thanks for the kind words man! Things are going more or less ok, I was the chief editor for a massive book on polyrhythms by Henrique De Almeida. Now working on an Afro-Cuban book with him. I haven’t had much desire for new videos lately, but it’s probably time for a return :)

[@eelamite]

will be on the look out for that! @@YaroslavKurilo thanks
