"The word 'Madrigale,' as the title of a musical composition, is found from the late 13th and early 14th centuries when, in Italy, it was applied to secular unaccompanied vocal compositions for two or three voices in the simple harmony of the day. Unlike most choral music of this period, the madrigal was free composition; ie. it was not a mere addition of free parts to a fixed part (canto fermo), but was free in every part." - The Oxford Companion to Music

Madrigale is a composition from 1979 that exploits temporal variation and timbre. It is originally scored for the unusual trio of piano four hands and tape - the tape part being a ercording of the glockenspiel and vibraphone parts.

Aldo Clementi IT

 Aldo Clementi (1925-2011) began his piano studies at the age of 13. At 16 he began studying composition in Catania where he later became a pupil of Alfredo Sangiorgi (a student of Schöenberg in Vienna in 1922-23) who introduced him to the technique of twelve-tone composition. From 1952 to 1954 Clementi studied in Rome under the guidance of Goffredo Petrassi and attended Darmstadt. From 1971 to 1992 he taught music theory at the University of Bologna (DAMS) and regularly gave lectures and taught composition courses at other universities. In 2005, numerous monographic concerts celebrated the composer’s 80th birthday, including an international conference on Clementi’s music at the University of Catania on which occasion the composer received the laurea honoris causa. During the Festival Suoni e Colori in Toscana Clementi he was awarded the prize Presidente della Repubblica; he also earned the DAMS Special Prize for his career from the University of Bologna. 

Aldo Clementi passed away in March, 2011.
