tell me nothing except about the 'grand recital.' let the rest go to 'hell in a handbasket.' make the grand recital, ok. give yourself some time. november is good. you see, nothing good comes when one only has a day or a week to prepare. may as well just put on a poker face and get it over with. teachers know anyways. and, the better you are - the worse it is. beethoven slapped one of his sixteen year old students on the hand, walked out the door, and never came back. but, then, i think later composed something for this student.
don't worry. it'll be alright (cringes). you can always be sick the first few months and suddenly get better in november. what are you playing? or, planning to play.
ps back in the day...i recorded myself playing my piano music and listened to it at night. the right tempos, the phrasing i wanted, everything. if there was a part of the music i couldn't visualize or quite remember - i'd go to the piano in the middle of the night. it's a bit obsessive.
