When I make a score, I am always wondering if the musician is able to play it. Is it possible to go directly from D to A on the violin? Is it possible to play rapidly from G to C on the trumpet? And how many quarter-notes in succession are musicians able to play? What about the recorder (blokkføyte)? I remember there was one strange grip from when I was a child, but half notes on the recorder? I don't know, and I have to take chances. And I am always impressed when I hear the score in fact being played.
