What time signature is this?
So, I'm currently writing an orchestral piece with complex time signature changes. One part that I wrote has two quarter-note triplets defined as one beat. And I don't mean two triplet-groupings, but just two notes. Let's say I play that four times to get one bar, what would the time signature be?
This change comes after a 4/4 part, so length-wise (in seconds) it's two thirds of the 4/4. I guess you could argue it's just a tempo decrease, but like... in 100 BPM that would make it 66.666etc BPM, which obviously isn't possible. Plus, it isn't really, right? That would be like calling metric modulation a tempo change.
I thought at first that would make it 2/6, but after looking it up, apparently that would be two dotted eighth-notes, so I'm kinda lost as to what this would be.
