CPO, I would bet a donut that your teacher most likely already has your next recital already scheduled in her planner and most likely already has the piece of music you will be working on for it in mind.  She probably won't tell you about it until a lesson or two after this recital has passed and your jitters have had a chance to die down a little. 

Now before you go getting upset over that thought, stop and think.  You have worked your tail off getting Scarborough Fair ready for this recital, and I am sure that your overall playing has definitely improved on other pieces of music you play as well.  Would you have really put the same amount of effort in if you hadn't had a performance coming up?  I doubt it.

It is an effective motivator, and your teacher would be plumb stupid not to use it when she is getting paid to train you to be a better musician.

Besides, whether it is a recital, jam session, open mic session, gig, concert or whatever.. Performances actually are part of the fun.  The first ones may seem more like an ordeal than fun, but they pass, and as you get a few under your belt you may actually start to look forward to your next show. 

And a gold star..for deciding your hubby will be attending your recital.
