I’ve recently been reading up on time signatures and obviously know how to read them, but when determining the right time signature for my music I’m having a hard time differentiating between 4/4, 2/4 and 2/2 and between 3/4, 6/8 and 3/2. Here’s what I mean:
I can write the same musical phrase in 4/4, 2/4 and 2/2, using the same note values. Similarly, I can write the same simple waltz in 3/4, 6/8 and 3/2, using the same note values. How do I determine what time signature to go for and is there only one right answer or can this be an arbitrary thing? What do you use as guidelines when determining the time signature? Is it scoring efficiency related to tempo?
So what’s the difference between a 3/4 measure with 8th notes and a 6/8 measure with 8th notes? Or what’s the point of using 2/2 instead of 4/4?
Who can give some clear guidelines?
Thanks a lot!
