The subject for analysis were works for voice and piano by selected Polish composers of the 20th and 21st centuries, e.g. Grażyna Bacewicz, Tadeusz Baird, Henryk Czyż, Henryk Mikołaj Górecki, Henryk Hubertus Jabłoński, Wojciech Kilar, Zygmunt Krauze, Szymon Laks, Witold Lutosławski, Juliusz Mieczysław Łuciuk, Wojciech Łukaszewski, Paweł Łukaszewski, Maciej Małecki, Paweł Mykietyn, Edward Pałłasz, Konrad Pałubicki, Krzysztof Penderecki, Witold Rudziński, Marian Sawa, Kazimierz Serocki, Tadeusz Szeligowski and Romuald Twardowski. An important matter for the author was to determine whether there are common features for this creative genre. She also attempted to find an answer to the question if the trends from the second half of the 20th century were reflected in songs. The scope of analysis covered the repertoire the author knew from her performance practice from the standpoint of a pianist. To the general characteristics of selected songs she added a review of famous trends, techniques and styles of composition, such as impressionism, neoromanticism, expressionism, dodecaphony, serialism, punctualism, minimalism, sonorism, spectralism, neoclassicism, vitalism, postmodernism, aleatoricism, bruitism, microtonality, electronic music, musique concrète, stochastic music, references to previous periods, to folklore and to popular music. She compared musical notation of the analysed works. She also confronted forms of songs with contemporary composition techniques. Interesting was the approach of composers to chamber relations in a duo and the way they made texts musical. Most composers distanced themselves from the avant-garde in works for voice and piano which had a specific poetic text because of the clarity of narration. Matching composers unequivocally to just one trend turned out impossible. Various techniques and phenomena may co-exist in one piece and in the same way one creator may search for different means of expression. [ABSTRACT FROM AUTHOR]
