Weeping Willow, a Scott Joplin Rag and a piece by a Russian composer. The latter hasn't been determined as yet. I'm awaiting the delivery of a book of works by various Russian composers, from which my teacher and I will select a second recital piece.
But the point I was making in the previous post is that I'm practicing on a digital and will "recite" on a grand piano that will be totally strange to me.
So when you consider the snippet from richy321"s post...
I will tell you that even the best digital piano with "grand piano action" and weighted keys (both of which are merely marketing gimmicks in my opinion) will do serious damage to your sense of touch and will take years of hard work on a real piano to undo. The very fact that the digital can produce beautifully even sounds regardless of how crudely you play, as long as you hit the right notes, destroys one's ability to control dynamics on a real piano in short order.
...you'll see why I am now worried. Great news, Rich Y.
Thanks!
Don´t worry. You will have no problems at all. There is far more variation between acoustic pianos. For one thing, if your digital piano is a top range Yamaha, chances are that the grand you will be playing will also be a Yamaha, in which case both the sound and touch will feel almost the same.
There is a much more discernible difference between a grand and an upright acoustic for several reasons (the mechanics is different: the grand has a double escapement mechanism that an upright lacks; in a grand the hammers return by gravity, in an upright by springs, etc. etc.).
Besides certina grands are terrible to play in. I used to dread going to recitals to accompany my recorder students and finding a Bechstein there (for some reason I have never seen a new Bechstein: they were always old ones, out of tune, with heavy action and sticky keys).
Some people can get quite snobbish about piano sounds - usually at an age where they have already lost the ability to discriminate the higher and low frequencies of the spectrum.

The best (and only way) to deal with this sort of thing is to arrange a few rehearsal sessions withteh piano you will be playing so that you can figure out its idiossincracies. A lot of "golden age" pianists would only perform on their own pianos, and would carry them around on tours (Paderewsky, Michelangeli, Hoffmann). More recently Andras Schiff has been doing the same, and goig one step further: He takes two pianos with him on tour: a Bosendorfer and a Steinway because he believes that different repertory will sound better in one or the other.
Best wishes,
