John Cage was an American composer who is known for his experimental approaches to music. Some of his new musical approaches include:

• Chance operations: Cage often used chance operations, such as the I Ching, to determine the structure and content of his compositions. This meant that the music was not predetermined, but rather created through a series of random events.

• Incorporation of non-musical objects: Cage experimented with unorthodox instruments, such as household items and metal sheets, to create new sounds. He believed that everything in the world has a spirit that can be released through its sound.

• Preference for chance over melody, harmony, and texture: Cage preferred chance operations over the elements of melodies, harmonies, and textures in music since he perceived these elements as the working of his ego. Therefore, the use of radios in Cage’s music reflected his liberation from thoughts, egos, and will.

• Musical soundscape: Cage wanted his music to be a musical soundscape instead of a musical composition. He was conveying the message that music itself is everything happening at the moment, which is the reason his music stands out among all aleatory music.

• Collaboration with performers: Cage worked with performers to create new sounds and explore new possibilities in music. He organized a percussion ensemble that toured the West Coast and brought the composer his first recognition.

Overall, Cages experimental approaches to music challenged traditional notions of composition and performance, and his influence can be seen in the work of many contemporary composers.
