FLEXUOUS MUSIC is a form of art music that employs limited musical motifs, figures, and melodic cells. In FLEXUOUS MUSIC, there is always a minimum of two musicians who work with limited materials and who perform an identical music stuff without listening to each other. The musicians pay attention to the tempo, rhythm, dynamics, and of course to the melody of the piece written in the score. But they don't listen to each other whilst performing. Although they mostly start playing each composition simultaneously, after several measures they gradually break apart. They live their own musical lives independent from each other. In this way the listener is inconspicuously involved in a blurred, quaking image of unexpected sound fibres. 
​FLEXUOUS MUSIC represents a new approach to the activity of listening to music by focusing on the internal processes of the sound. The harmonic sonorities of FLEXUOUS MUSIC are distinctively simple, and usually diatonic. FLEXUOUS MUSIC is also characterised by an unsteady tempo, usually continuing throughout the whole piece.
Since early 2000s Peter Machajdík has created a couple of pieces in the style of FLEXUOUS MUSIC.
