Notes about update #004 of The Modern mixtape.
Polymorphia by Krzysztof Penderecki is a modernist classic from 1961. It is scored for 48 strings and Penderecki uses a lot graphical notation to build clusters of sounds. The result is brutal and harsh. The ending C major chord is quite surreal. It was used in the soundtrack of both The Exorcist and The Shining.
Another modern classic is Gruppen by Stockhausen. It is scored for three orchestras and each orchestra is conducted by a separate conductor. The idea is that Stockhausen had is that you have groups of notes that have characteristics in common. It can be the timbre or if all notes have high pitch. In Gruppen each group also share the same tempi. Thats why there are three orchestras with individual conductors. Another reason is the spatial possibilities that you can explore when you place the orchestras at different places. Stockhausen made a lecture serie in England 1972 where he among other things explains the theories around groups and point. It is available on youtube here.
