Re: meters

yeah, the rythym patterns you describe are usually notated in 5/4, not 10/8. in fact, you almost never see 10/8, except in music that doesn’t have a reoccuring rythmic break down. you’re likely to only find 10/8 in something like stravinsky, where it might be sandwiched between a bar of 3/8 and a bar of 11/8, and so would be natural in that context.
