I'm still an amateur composer, but I've been wanting to explore time signatures outside of 4/4. The trouble is, I'm having issues figuring the actual time signature of what I've written. I was arranging the track with my DAW set to 3 beats per bar at 135bpm. However, when I went to transcribe it onto a sheet, I started questioning exactly what the best time signature is to express the song.
The song follows this drum pattern. A snippet of the actual arranged song is this. Finally, a basic computer-played piano arrangement sounds like this, but it is quite flat in terms of dynamics so I'm not sure it's very helpful.
I'm heavily leaning towards 3/2 at 67.5bpm per half note, especially because I think the piece is a lot slower than I would expect 135bpm to sound. Any help identifying what would fit best would be really helpful!
Below, I've transcribed the sheet music in the various signatures. I'm still new to making sure rhythms are properly grouped, so if you notice an error, please feel free to point that out as well.
