The major part of Jonas Paulikas' creative output consists of chamber pieces for various instrumental settings which display certain features characteristic of neoclassical style. For instance, he often opts for traditional genres, such as invention, passacaglia, suite, concerto, sonata, quintet. Polyphony is one of the key elements in his works that often employ canonic technique, imitations, various contrapuntal combinations constructed and developed according to the principles of serial music. Pieces for folk instruments make up another important area of Jonas Paulikas' work notable for resourceful and innovative treatment of folk instruments and their technical possibilities.
