Penderecki's Concerto doppio per violin e viola was composed in 2012 on the occasion of the 200th anniversary of the Wiener Musikverein. The Concerto doppio is a piece with a clearly outlined neoromantic architecture. Although the composer often uses semitones as form shaping means, the Concerto is also saturated with many consonant solutions mitigating tensions. Penderecki's Concerto per viola ed orchestra has been transcribed for a variety of instruments. The original version was created in 1983 as a result of a composing commission by the Venezuelan government in the context of commemorating the bicentenary of birth of the hero of the fight for independence of South America- Simon Bolivar. Completed in 2003, the Concerto Grosso No. 2 for three clarinets and two basset horns, apart from the Spanish premiere has not been presented to a wider audience for 15 years. It is a composition that is difficult to consider only in the context of the inspiration with the form of musical expression developed in the Baroque.
