1926 - died Paris, 31 May 1996) is known for his experiments with microtonality. He wrote one opera, Antigone (1990–1991). Lex van Delden (1919–1988) was an important composer. Louis Andriessen (June 6, 1939 in Utrecht – July 1, 2021) was a composer whose early works show experimentation with various contemporary trends: postwar serialism (Series, 1958), pastiche (Anachronie I, 1966–67), and tape (Il Duce, 1973). Andriessen's mature music combines the influences of Stravinsky and American minimalism. His harmonic writing eschews the consonant modality of much minimalism, preferring postwar European dissonance, often crystallised into large blocks of sound. Large-scale pieces such as De Staat ['Republic'] (1972–76), for example, were influenced by the energy of the big band music of Count Basie and Stan Kenton and the repetitive procedures of Steve Reich, both combined with bright, clashing dissonances. Andriessen's music is thus anti-Germanic and anti-Romantic, and marks a departure from postwar European serialism and its offshoots. He also played a role in providing alternatives to traditional performance practice techniques, often specifying forceful, rhythmic articulations, and amplified, non-vibrato, singing. Other notable works include Workers Union (1975), a melodically indeterminate piece "for any loud sounding group of instruments"; Mausoleum (1979) for two baritones and large ensemble; De Tijd ['Time'] (1979–81) for female singers and ensemble; De Snelheid ['Velocity'] (1982-3), for three amplified ensembles; De Materie ['Matter'] (1984–88) a large four part work for voices and ensemble; collaborations with filmmaker and librettist Peter Greenaway on the film M is for Man, Music, Mozart and the operas Rosa: A Horse Drama (1994) and Writing to Vermeer (1998); and the recent La Passione (2000–02) for female voice and ensemble. Significant composers after Andriessen include Klaas de Vries (b. 1944), Jacob Ter Veldhuis, a.k.a. JacobTV (b. 1951), Guus Janssen (b. 1951) and Cornelis de Bondt (b. 1953). Folk Dutch folk music, is characterized by simple straightforward bass motives heavily supplemented with fast, often happy, melody. (Click here for an example.) Uncommon among other European folk, in Dutch music the bass line, not the melody, is the musical line that is danced to. This means that though the music itself may sound fast, the dances are usually quite moderate to slow in tempo. The dances themselves are mainly group dances rather than individual or dual dances. Clogs are often worn during dances; however, Dutch clog dancing is very different from its more modern counterpart. It is virtually impossible to perform
