Most of all, I give myself plenty of time to get familiar with the composition, to “grow into” its concepts. The composition “congeals” under your fingers and in your heart; each phrase becomes yours, and the artistic expression, which emanates from the piece, becomes your expression. Artistic intuition also plays an important role, although it is difficult to determine why a particular idea for interpretation seems to be right. You just know. You feel it. Of course, this intuition is being fed by theoretical knowledge, including knowledge about the composer. But the starting point is in the notation. Also, there exists something that is not written down. I am talking here about that space between the notes, where you have more freedom. However, you always need to be aware of the notation, because if you treat this space too liberally, you can make an interpretative mistake and destroy something that should be left intact.
