Module 3 conveys a complex analytical chart to …..sofferte onde serene…. It is intended for practitioners who are studying the piece (composers or performers), and it includes minute compositional details. It is made of four basic elements: (1) a graphic exposition of the score that renders visible the formal sections and subsections of the piece; (2) analytical diagrams focused on pitch and rhythmic structures/reductions; (3) audio recordings (piano alone, without tape) of every subsection; (4) denominations of the sections and subsections according to Luigi Nono (blue) or made by the author of this exposition (orange-red). Together, they allow recognition of some fundamental aspects of the score: (1) Form. A complex imbrication of sonata and variation forms, including an explicit ‘recapitulation’ after the climax, and ten implicit ‘variations’ on an underlying pitch structure. (2) Counterpoint. Use of imitative and canonic processes of writing. (3) Harmony. Use of ‘harmonic fields’, highly recognisable sound-aggregates with additive pitch processes; use of additive chord techniques, adding chords to one another but breaking their identity. (4) Use of rhythmic cells, small units that structure big sequences without serial/numeric controllers.
