Thank you very much all of you! I'm slowly figuring out, how ignorant I've been about the right warm-up
@Eddy: Just teasing oneself before the performance is a good idea! It would be a very good way to prepare oneself for a performance, especially if you are an experienced performer or you are familiar with the condition on which you have to play. The I. Phillp's exercises are unknown to me, so I'll try to find them in IMSLP.
@Andrew: I'll surely try out your suggestion about the finger moving/massaging during waiting for my turn! The other concrete suggestions are also very appreciated!! And wow, improvisation as a warm-up! I'm not talented at all in it.
@hanysz: Hi, welcome to PS and thank you very much for your kindly obliging reply!
Do I understand you correctly: you have only played in public three times during the last year? It takes a lot of experience to get these things right. My first twenty public performances were terrifying; it was only later that I started to enjoy it.
I'm a PhD student of the philosophy and have a young baby, so actually have no time, to give or to organize myself more public performances
But you're right in that three performances in a year are too little.
In what ways was the piano different from the piano(s) you usually play?
My main problem with the unfamiliar pianos is that I feel so uncomfortable with the unevenness of actions and mostly too loud volume of them.
What repertoire were you performing?
The pieces I performed in the last year were the very pieces I submitted on the Audition Room: Rachmaninov's transcription from Bach's E major violin partita, Bach-Kempff "Jesus bleibet meine Freude", Liadov's Barcarolle. On an occasion I played the preludio from that Bach-Rach as the first piece, messed it up and thought that it was my mistake to play such a difficult piece as the first piece, and after the long waiting for my turn. So on the next time I chose the Bach-Kempff, cause I thought it's an easy piece, but I messed it up, too. Comparing to them, the second pieces were always much better.
What exactly were you doing while waiting to play?
Well... I was eating or chatting with other people there...
All the three occasions are not completely devoted to the music, but I was there to frame meetings/parties musically on the piano. So while I was waiting for my first piece, the other responsible people were greeting to the guests or something like that.
Could you give detailed tips for me? Thank you in advance!!!
