"Like an apparently strict musical form it breaks the five minute whole into its structural parts - a descriptive preamble, the action of taking the cards, the development of the cards' manipulation and the revelation of what has been achieved"

In the quote by Gavin Bryars, the contrast of a five-minute section to a rigorous musical form supplies a structure for analyzing the structure and process of an imaginative or artistic work. Bryars equates this temporal period to a musical composition, recommending it is thoroughly arranged yet efficient in producing an impactful outcome. The breakdown into distinct parts-- similar to movements in a symphony-- permits each segment to add to the general story or creative expression.

The first structural part, "a descriptive preamble", can be seen as the intro or exposition. In music, this would normally develop styles or themes; here, it sets the stage through description, priming the audience and supplying context. Just as a musical intro might describe the secret and tempo, a descriptive preamble lays out the fundamental components and prepares the audience for what is to come.

Next is the "action of taking the cards", which signifies a definitive minute or a pivotal action. This stage marks the transition from mere information to vibrant engagement, akin to the thematic advancement in a sonata. It reflects a deliberate relocation from potential energy to kinetic energy, which drives the story or efficiency forward. This mirrors how musical development takes preliminary concepts and broadens upon them, adding layers and intricacy.

The "development of the cards' adjustment" pertains to the ingenuity and creativity used once the preliminary action is taken. In music, advancement is where themes are explored, expanded, and frequently transformed, showcasing the developer's skill. Similarly, this part of the procedure shows manipulation and proficiency, suggesting efficiency and innovation in dealing with the 'cards'-- or components of the artistic piece.

Lastly, the "discovery of what has been accomplished" represents a climax or resolution. Analogous to the recapitulation and coda in music, it is where all preceding actions culminate and the outcome is revealed. It provides closure, completing the narrative arc and satisfying the promise of the opening preamble. Through this careful structure, similar to in music, Bryars recommends that the whole, more than mere amount of its parts, emerges as a meaningful and impactful artistic expression.
