Thesis for Flute solo (2001)

The title refers to the character of the fragment which opens the composition. Repeated with small modifications, its small musical figures constantly repeat with the same high pitched sound. Each figure is always played in the same way: with the biggest initial energy, firmly, as if a concrete statement was being made, as if one were trying to convince someone of something. A similar phrase closes the composition, whereas in its central section, at a slow tempo and low register (here the performer swaps a C flute for an alto flute), a specific melody emerges. Its subsequent notes are played with ever changing articulation, always the same for a defined range.

I composed this Thesis in 2001 for the renowned flutist Carine Levine. In that same year, she performed it in Germany for the first ever time. Ever since then, the piece has been played numerous times, by renowned flutists such as Mario Caroli and Łukasz Długosz.

Carine Levine – Flute

Composer Tadeusz Wielecki

Born in Warsaw in 1954, he studied the double bass performance (with Alfred Wieczorek and Andrzej Mysiński) and composition (with Włodzimierz Kotoński) at the Music Academy in Warsaw. Thanks to a Witold Lutosławski grant, he continued his compositional studies with Isang Yun in West Berlin and Klaus Huber in Freiburg i. Br. (1986-1987). As a double bass player he focuses on the contemporary solo repertoire. He has performed in many European countries, Asia, and the United States.

He is also active as an improviser, playing with musical ensembles such as Mud Cavaliers and Laterna. In 1995 his A Very True Story for tape received the highest award at the EAR radio competition and Budapest, and in 1999 his Concerto à rebours for violin and orchestra (1998) was commended at the UNESCO International Rostrum of Composers in Paris. He is also active in the field of promoting contemporary music and arts education. He ran several cycles of radio programmes introducing children into the world of new music and cooperated with the Children’s Arts Centre in Poznań and the Okopowa Cultural Centre in Warsaw. He was Artistic Director of World Music Days in Warsaw in 1992. In 2004 he was invited as a lecturer to the Darmstadt Summer Courses for New Music.

His works have been commissioned by institutions, festivals and ensembles such as Warsaw Autumn, Polish Radio, Poznań Philharmonic, de ereprijs, the Darmstadt Summer Courses for New Music, Klangspuren in Schwaz, Klangforum Wien, Hiroshima Symphony Association, Klangforum Wien, New Music Orchestra (OMN) in Katowice, Forbidden City Chamber Orchestra in Beijing, Plural Ensemble in Madrid, Ensemble intercontemporain, Music Workshop, Silesian Quartet, and many other ensembles and institutions.

Tadeusz Wielecki served as Director of the Warsaw Autumn International Festival of Contemporary Music between 1999 and 2016.
