Hey, small world! Good to run into you here.
Which reminds me... It's been about a decade since I've updated my web page. I should get around to that at some point.
Anyhoo, I obviously didn't explain this well.
The time signature 3/2 means that you've got 3 beats per measure, and each beat is notated as a half note.
The time signature 3/4 means that you've got 3 beats per measure, and each beat is notated as a quarter note.
The
only difference between 3/2 and 3/4 is one of notation. The two pieces of music above sound exactly the same.
In contrast, 6/8 time is
not reducible to 3/4. The numerator indicates that there are 6 pulses to the measure, so changing to 3/4 would change the basic unit of pulse from 6 pulses per bar to 3 pulses per bar.
So if you're asking how you would build a song in 3/2 time in BiaB, you'd do it by dividing the duration of each note in half, and notating it in 3/4 time.
Did that make sense?
