On Saturday, March 13th I'm going to play a bit of recorder along with a harp ensemble. One item we are playing is a combo of two Scottish pieces, 'Drummond Castle' in 6/8 time followed (without a pause) by 'Sleep Soond i da mornin' in 4/4.

I know there's supposed to be some kind of equivalance in the tempo when you do a thing like that. A Something in the first piece is supposed to last as long as a Something Else in the second piece.

Does anybody know how these things work?
