4. Material versus Structure 4.1. Conceptual Framework. Material and Immaterial Structures

Although any material is a structure (macrostructure, microstructure, etc.), not any structure is a material, since there are immaterial structures , such as a literature work (novel, poetry, etc.) or a music score, e.g., a Bach’s Cantata or a Beethoven ’s String Quartet.

4.2. Immaterial Structural Integrity: Recalling Miguel de Cervantes and Johann Sebastian Bach

Fig. 6 shows the portrait of Miguel de Cervantes Saavedra by Juan de Jáuregui and the cover page of the novel Don Quijote de la Mancha, an impressive masterwork whose immaterial structural integrity must be preserved by reading the whole work completely and not only a single Chapter.

Fig. 7 shows the portrait of Johann Sebastian Bach by Elias Gottlob Haussmann and cover of the Christmas Oratorio ( Weihnachts Oratorium ) BWV 248 , a colossal masterwork whose immaterial structural integrity must be preserved by performing the Oratorio (six Cantata) as a whole and not a single Cantata.
