Q: hi, im kind of curious how time signatures work. like, i can recognize the beats in songs, and i know rhythm notation (quarter notes, eight notes, sixteenth notes, triplets, blah blah blah).. i know what time signatures mean, as in i know 4/4 means 4 quarter notes to a bar, or 6/8 means six eighth notes etc.. but what actually determines how you set the time signature if you're writing something out, like where to draw the barlines? can't you think of 4/4 as being 2 groups of 2 (2/4)?
A: sure
