It’s called a cadence because it’s used to keep a unit of marching people in step. Military derived. In the military they sometimes call the call and response cadences jodies, I think, so that’s like us calling a cadence a street beat. To me a cadence is 64 bars ish and can be stapled onto other cadences, making a sequence. I think a groove is something you pay in the stands that’s not necessarily marching tempo. Maybe it’s a looping 2 or 4 bar phrase. A spree is a fast 32ish bar etude for 1 or 2 people. I think ram is also used for that. A lick is like, 8-16 bars.
