A brass band is booked for a return concert to be performed with a local choir. Band and choir are poised to begin an afternoon rehearsal prior to the big night, and the band's Musical Director addresses the choir :-
"For the big finale, we will start in G minor and then on the third bar, modulate to B major and go into 5/4. When you get to the chorus modulate back down to F# minor and alternate a 4/4 bar with a 7/4 bar. Put a massive rall at the end of the 1st chorus. Then in the 2nd verse we'll go into A major, raise the tempo at the chorus then slowly modulate back to G minor."
The choir protest and exclaim "Wow, I don't think we can remember all of that."
The band MD says: "Well, it should be easy, that's what you did last time."
