Imagine going from 4/4 to 12/8. in 4/4 an eighth note triplet is one beat, and you need 4 of those to finish the bar. then 12/8 you still have 12 8th notes, but now each one is one beat, so to go 4/4 to any signature over 5 you would have to know what feel you're going for (aka triplety like 6/8 or driving like 2/2 or hectic like anything over 16 lol) then say you wanted triplety you would have to see what a fifth note triplet is like in 4/4 then just like changing from 4/4 to 12/8 you would do the same to 4/4 to ?/5
Hope that makes sense. Basically you have to decide the feel you want, if you just want a constant straight pulse then theres no point in not writing in 4/4, but if you want a new feel then go ahead and try something over 5!

It doesn't, time signatures with 5 as a denominator don't exist, and 12/8 is basically interchangeable with 4/4 swing anyway.

Technically yes it doesnt exist, and formally it doesnt either because its illlogical and complicated, but the thing with music is that its based off of math and so the numbers could be right to make a five time, but again as said by this entire thread it can be written much easier many other ways. not only easier but hoe it shoild be written, there arent any benefits to a five time

And it's for this reason that it's always written 5/4, and never 4/5.

Yes, 4/5 technically exists because it's created in a sequencer. But what happens if you put it to musical notation for some reason or other (or if you're bound to)? There are no notes with a 5-count at all. There are whole notes, half notes, quarter notes, eighth notes and so on. Those are all multiples of 2 counts. And then you have the dotted half notes and so on, which are multiples of 3 counts. There is no single note in music which equals five anywhere.

So you can have anything ending with /2, /4, /8, /16, rarely /3, but NEVER /5.
