What is the fine-grained topic of the following text: A musician, then, attempting to play and replay, indefinitely, the same short moment of music, would be subject to the decomposition of that action already contained in that attempt; would be venturing to separate his own ‘general stream' of the experience of playing from the analysis of having played it before and before and before. Only return the topic.
The psychological experience of a musician repetitively playing the same piece of music.
