Ginsberg reads his poetry like a mantra, often ending lines with a rising intonation. The similarity between the temporal construction of a jazz creation and a poetic one is acute. Music happens between certain constrictions, those of beat and count. Clearly, poetry behaves in a similar manner. Time is not oppressive if one knows how to use it effectively, which jazz musicians and Beat poets knew how to do.
Time is another reed, or other nib, if one utilizes and expands within it.
As alluded to by Kerouac, spontaneity is the most vital and defining characteristic of jazz. Thus, the conditions of Now are right for improv, which the talented musician recognizes, but which fall upon the audience's ears serendipitously. Simply, the technique is taken for granted and surpassed, while the attentions of the player only needs to be conducive to the opportunity for improvisation. The essence cannot be hampered by forethought or planning, by discrimination or discernment. All thoughts are free, all thoughts are valid.
