To be fair, I think you missed my point. If you subdivide a 4-count into 8 beats, then you are correct, it might better be called 8/8 than 4/4. But the same logic wouldn't get you 7/8 instead of 7/4, it would get you 14/8.
No, I didn't miss your point. But I wasn't making the comparison you suggested (or "applying the same logic") at all. I was just saying that "how you subdivide affects the name" and giving 4/4 vs 8/8 as an example.
I never "subdivided a 7/4" anywhere or suggested that something like that would result in a 7/8. In fact, you kind of support my idea that 7/8 and 7/4 are different.
Taking your example: 7/4 is 14/8 arranged as seven even groupings of two 8ths. The other is 7/8 arranged in (usually) two groups of two 8ths and one group of three 8ths.
So 7/4 has seven even pulses while 7/8 has three pulses, one longer than the two others. I'm also aware that in different cultures there may be lots of different groupings, like 2-3-2 or something like that, but that is still a 7/8 to me.
Now I KNOW that people will argue that as tempo gets higher one will feel the "half notes" and will begin to feel the "short/short/long" (or vice versa) pulses. Well, I suggest that you are now playing and feeling a 7/8.
I have never met a drummer that has played 7/4 the same as 7/8 regarding the placement of snare and kickdrum.
I don't like to "argue" on the Internet so this will be my last post on the subject matter. I hope I have expressed my position in an understandable manner. It's just consuming more time than I have for this forum, so please don't see this as rude. Thanks for the respectful exchange of opinions.
