Concerto Abbreviato is a musical composition for solo clarinet written by Petar Bergamo, for Milenko Stefanović,[1] who gave its first performance on March 16, 1966,[2] on his tour in UK, and recorded it, the same year, for PGP-RTB.
Written in one single movement, it is based on a theme consisting partly of a sequence of chromatic tones hidden behind the intervals of the ninth, the diminish octave and seventh.
Gradually condensing the musical texture and accelerating the tempo, the author creates a gradation of extraordinary force, reaching the climax in the part marked con brio.
This Concerto makes masterful use of some new possibility of the clarinet, such as flutter-tongue or effect of a dual tones which is the result of differentiation in dynamics.
[3][4] This composition won Yugoslav Radio-Television Prize (1966) and was selected as an obligatory piece for the Jeunesses Musicales International Contest in Belgrade (1971)
