When I was in Van Halen I was hitting notes that were out of my range. I never went for those registers before until Eddie pulled it out of me.
I don't think I handle the notes much differently from other pianists. But the pauses between the notes - ah, there is where the artistry lies!!
When I sing, there is an almost constant struggle with pitch and with reaching notes in the higher register.
I had a very misguided notion of what 'network notes' were. I thought they were well-meant suggestions, perhaps urgently meant, but just suggestions nonetheless. And actually, they're demands. You have to do them, or you will not be paid.
