20th century music

Minimalism Serialism-1920-1930

• The technique is a means of ensuring that all 12 notes of the chromatic scale are sounded as often as one another in a piece of music while preventing the emphasis of any through the use of tone rows, an ordering of the 12 pitches.
• All 12 notes are thus given more or less equal importance, and the music avoids being in a key.
• Play all 12 notes in a random order and then you play it inverted(backwards)
• Then play in a retrograde(same amount of semitones between notes) may sound really random but is the most organised piece of music ever
• Not in a particular key
• Odd and clashy sounds

3 composers:
Berg

Schoenberg-inventor of twelve tone technique

Webern

Electronic music
Music that uses electronic musical instruments and electronic music technology in it
Can be made between sound produced using electromechanical means and that produced using electronic technology

Atonal music
Where a hierarchy of pitches focusing on a single, central tone is not used, and the notes of the chromatic scale work independently of one another

Aleatoric music
Music of chance
No rules
Composers were really random
