Hey Thal,The term 'playing up' has been described to me as the last part of a standard circular motion (that matches the body rhythm). Take, for example, the Grieg sonata in E minor, Op. 7. I the first movement, there are two instances of an arpeggio figure that ascends near the top of the keyboard. One would play this beginning with an attack (a down), and finish on the up. In the left hand, this is often used for fast leaps (as in la Campanella or Beethoven's Op. 31/1 first mvmt.). It is as if your hand is springboarding off the bass note.This, in any case, is my interpretation.Let me know what you find out!
I've heard people describe sound that goes 'up,' and I've read an article about Argerich which says she told a student in a masterclass to imagine they were playing the piano from beneath the keyboard, ie, playing up.If the latter is the case, I would guess it's a mental image that frees the hand from tension, because if you turn your hand upside down and pretend to play the piano, your fingers feel a lot stronger and more secure, especially the 4th finger.If it's sound, I think it refers to a general mental image designed to give a timid player more projection; when playing in crowded spaces, there's often a lot of ambient noise you've got to compete with, and you have to be able to project over it.
Paulpiano, I really don't think that was rubbish, and please don't put down other peoples' comments unless you have your own insight to add to the mix.
I believe he is referring to Argerich's suggestion in the first paragraph...
PS So far original poster has not said what context he heard this in, so I could be totally off the mark. Was it in the context of the sound, or the physical approach, or projection during performance, or what? Very curious to know.
An excellent teacher in my acquaintance talks about playing up--but she describes it in terms of managing weight. She seemed to want her students to play with rather light arms yet somehow transfer weight to the keys. I do not understand her approach, but she used the phrase 'playing up' quite a bit, and like I said, I also read it in a book. Thus, it must not be unique to this one teacher. So I was wondering if anyone else knew.
