Long time lurker, first time poster.
I watched a 3 part youtube series of a Steve Duda lecture at Pyramind. In part 3 around minute 37 he briefly speaks about the advice he gave Avicii on how to mathematically match the harmonic tempo of the song to the key of said song. I saw the same question in edmproduction that only skims the topic but doesn't completely go into depth. In my case let's say you have your tuning set at A4=440 Hz. After using the formulas I found in articles online, you will come up with a harmonic BPM in the key of A at 55 bpm or doubling that number to the next octave higher at 110 bpm. This leads to my questions. How would you break this harmonic bpm down into smaller intervals? If I wanted to write in the key of A but at a slightly slower or faster bpm, am I out of luck? Am I limited to these two vastly different tempos? Is there a method using music theory to break the intervals down the the 3rds and 5ths or maybe using semitones or cents?
I ask in relation to writing and composing songs on the production side, not mixing songs harmonically such as a DJ would do in his/her set.
Any advice appreciated thanks
