Fwiw, I don't think there's any difference between 6/8 and 12/8 ( i.e. 12/8 is just like 2 bars of 6/8). They both apply to slow and fast tempos, and seem to be used interchangeably.

If songs had an odd number of bars in 6/8, then it wouldn't convert to 12/8. The same thing happens in 4/4 through, where there can be a 2/4 bar or a 6/4 bar at places.


Have Fun!
