is a complex Piano solo, expertly composed by Anders Brodsgaard
in 1990. Joker
was inspired by Keith Jarret
's Piano style, particularly as it unfolds in his famous concerts of solo improvisation. The title comes from the fact that a kind of 'joker effect' is built-in in the rhythmic play which disturbs the 'arithmetical problem' and forces the music to continue every time a four-layered polyrhythm is about to come out.
The Danish composer began by writing rigorously structured pieces, inspired by the serial composers of the 50s. In his more recent pieces, Brødsgaard has been working with more fundamental musical phenomenon like tonality and pulse, still inspired by the post-Pythagorean idea of a musical continuum between the musical parameters.
