Say you are preparing an all-Beethoven recital of about 70-90 mins in 2 halves, what do you do? I am thinking of preparing such a recital for a concert that I have been asked to give at short notice (the recital is July - many of you would have seen the other programme I posted previously involving Bach/Beethoven/Debussy/Liszt, but I dont think I can prepare this in time). Anyway, here are my thoughts:
Sonata No. 24 in F#, Op. 78
Sonata No. 2 in A, Op. 2 No. 2
INTERVAL
32 Variations in C minor, WoO 80
Sonata No. 18 in Eb, Op. 31 No. 3
Yeah! Beethoven rules!

However, some questionst that come to mind (first impression).
1. Do these really make up to 70 min? I think it would hardly be an hour. Or do you count the Intermission? Anyway...
2. Are these the sonatas/variation you will definetly play, or are these just suggestions?
Okay, however the answers may be, I actually think it is a very good programme. You have Sonatas in three completely different styles: early, middle, and nearly-late. The 32 Variations is very cool, and op. 31/3 at the end is also quite nice (eventually a Finale deserving this title).
Problems could be that you play no real hit, no famous Beethoven. Now, for me personally, I would really appreciate this recital, hearing some pieces you don't get to hear so often (especially op.31 and 78 which I like very much).
So, for which kind of audience are you playing? What is the occasion? You might consider changing one of them to a more known sonata (Waldstein/Appassionata/Tempest obviously for the op.31/3, OR a really late sonata for the op. 78 (90/109?, although I would not start but end with one of the late 6).
Of course, these alternatives are much harder than your pieces, so if you don't know them (see question 1) forget it, and play your programme. Perhaps you want to consider learning an encore? "Rage over the lost Penny" (op. 129), "Polonaise" (op. 89), "Fantasia" (op.77) come to mind, or "Six Ecossaises" often played by Kissin. These pieces are all learnable till July if you have some time to learn (so, if you are not spending all your practice time on polishing your recital pieces...).
Anyway, nice programme. I would come...all Beethoven, cool.

Good luck
