Before recording technology, music referred only to live music. So when the recording media first appeared, the transformation of the music paradigm was profound. The experience of listening to music was seldom repetitive before recording, unlike listening to a tape which is more or less identical at each hearing. In addition, this experience is also shared by everyone who listens to the same recording, making commonality of message and musical experience a unifying social ritual for the first time.
The underlying philosophy of tape music spawned a whole new direction in musicianship, and music styles that would follow. Electronica, new age, rap, and other incarnations are direct descendants of the original tape music philosophy.
