experimental music

experimental music 

• 60's-70's (same time as minimalism)
• ignored the old rules of music 
• aleatoric music is made by chance
• composers will create the basics but how the piece is played is left up to the performer
• some pieces ask the performer to roll a dice to decide how the piece is played
• no piece will sound the same
• music is written out on a graphic score uses symbol and shapes…
