Form (Exercises 81–90)
The form of a composition is generally associated with its structure and evolution in time. The duality between similarity and contrast is vital when analyzing or composing form. Exercise 81 is based on the idea of contrast between sections; the goal of number 82 is to work with music blocks or modules; 83 is focused on the concept of developing variations as a formal approach (the variation of the variation). Exercise 84 brings back the traditional concept of variations on a theme; similarly, number 85 uses the traditional rondo form as a model. In 86 the core is the use of repetition as in minimalist music; 87 proposes an exercise about palindromic formal structures. Based on Earle Brown’s Available Forms, number 88 proposes a framework to challenge the idea of musical form as a fixed entity; 89 is about composing monolithic structures. The last exercise of the chapter, number 90, offers the opportunity to compose and explores ruled-based game compositions.
