The Haydn concert in D-Major is a compulsory piece both in studies and for auditions. When I started working on this concerto, I kept putting off the cadenza of the first movement because I felt no motivation to practice it. After all, there were only a few weeks left until the start of the semester. Finally I thought: the cadenza was originally intended to show the skills and imagination of the respective performer. I sat in a room in Salzburg in the Mozarteum and simply improvised based on the themes of the concert. I took complete freedom to try out all sorts of crazy things. Finally I called my mother and showed her my sketches. She was enthusiastic and suggested adding more lightness and variety of line styles. So this cadence was created within two days.
