Creating a cadenca (Boccherini Concerto No 3 in G Maj)?
I need to create a cadenza (A virtuoso passage inserted near the end of a concerto movement) for cello for the first part of Boccherini Concerto No 3 in G Maj (Allegro, starting at measure 98 in my score). It must be different from the cadenzas given in the editions. I´m a little bit dumbstruck how to start that task. Is there kind of a standard procedure to do so? How do you start that sort of thing? Do you know of a tutorial for creating such virtuoso passages? Any help to overcome my inhibition would be greatly appreciated.
