Trigonometry for recorder, oboe, trumpet, and tape

In the field of concertante music I have always been interested in the relationship between the performer and the music text, space and technology, as well as their influence on the duration and the musical form. In the early creative period, in orchestral, chamber music compositions and compositions for solo instruments, main features of my compositions were the following: use of graphic notation, creating the balance between improvisation and performing freedoms and therefore freedoms in planning the music form, planning mise-en-scène events. I often used mathematics and technology as the material for improvisation and enrichment. The inspiration lies in an idea. Trigonometry follows a similar school of thought as well as the approach to the concert stage and concertante music.
