Kraków and Łódź, whose mainstays were Matuszkiewicz, Trzaskowski and Kujawski. Later, he played with pop groups from Poznań. One of them, Jerzy Grzewiński's group, soon transformed into a dixieland band. Komeda appeared with Grzewiński on the I Jazz Festival in Sopot in August 1956, but he achieved success performing with saxophonist Jan "Ptaszyn" Wróblewski and vibraphonist Jerzy Milian, because dixieland did not meet Komeda's expectations at the time. He was more fascinated with modern jazz. Thanks to this passion, the Komeda Sextet was created. Krzysztof Trzciński used the stage name 'Komeda' for the first time when he worked at a laryngological clinic, and wanted to conceal his interest in jazz from co-workers. Jazz was beginning its struggle for respectability with the communist authorities in the era of 'the thaw' and with Polish society; jazz was regarded as a suspicious music of night clubs. The Komeda Sextet became the first Polish jazz group playing modern jazz, and its pioneering performances opened the way for jazz in Poland. He played jazz that related to European traditions and which was the synthesis of the two of the most popular American groups at that time: the Modern Jazz Quartet and the Gerry Mulligan Quartet. In the thirteen years after the I Sopot Jazz Festival, the artistic personality of Krzysztof Trzciński became more mature, crystallized and lyrically poetic. Krzysztof was, above all, a constantly searching poet who could find ways of individual expression of himself within jazz, in Slavic lyricism, and in the traditions of Polish music. 1960s The years 1956–1962 saw Komeda with his group taking part in domestic festivals and preparing ambitious programs. These were also the years of his first foreign successes in Moscow, Grenoble and Paris. A "Jazz and Poetry" programme was prepared for Jazz Jamboree '60, and later in Warsaw Philharmonic. Komeda's adventure with film music also began by this time. Scores for the films of Roman Polanski such as Knife in the Water (1962), of Andrzej Wajda such as Innocent Sorcerers (1960), and of Janusz Morgenstern Good Bye, Till Tomorrow (also 1960) were created. This period, which in Komeda's artistic biography can be called the period of growing up and improving his own music language, was crowned with "Ballet Etudes" performed on Jazz Jamboree ’62. Although the reaction of domestic critics for the Etudes was rather cold, it opened the doors to Europe for Krzysztof Komeda Trzciński. Komeda visited
