It's a single repeated measure in 1/4 time. To addres the real point, though, I don't think of a time signature as a rational number, although it correctly reflects what portion of a whole note can be found within a measure. I consider it to have two separate pieces of information: the length of the beat and the number of those beats per bar. When I've written code to represent music I have used rationals to represent when something occurs, but a different structure to represent time signatures. -- Brian

Time signatures are crap. They should have switched to a number over a note value a long time ago; we could have easily avoided abominable travesties like the time signature on the 2nd movement of Beethoven's 9th (B needed four over dotted quarter). If music notation had been invented by a computer scientist we wouldn't be stuck in the current mess in which 6/8 means two completely different meters (3 over quarter, or 2 over dotted quarter). And... er... Python doesn't need a time signature data type. But rationals would be quite nifty. ;-) -- Neil Cerutti
