1.4. Different manipulation techniques with the material obtained

Many of these techniques are traditional; some others are new. Some of them are applicable while the structural transfer from P1 to P2 is being carried out; others need other types of procedures.

Chart 7- Filters based on the colours: suppressing sound mass from a determinate colour, we give porosity to the structure, so that an architecture which had three colours would give seven possibilities of variation by silencing some of them.

- Temporal dyes: some colours can be temporally dyed so as to filter some procedure and prevent it from acting on the others. Eventually the initial colour is recovered.

Chart 8- Transpositions in height and space from X and from Y (the traditional retrogradation and reversal, and the less traditional inclination and turn, as well as contractions and expansions in one sense and in the other (height and duration), which can be achieved to the degree desired (not as in traditional systems which work with double, halves, etc.). We will see this later in the transformations of the plane by means of Iterated Functions. In inversions it is possible to control the axis of rotation with which we can bring about inversions which pivot on a hub axis of equal height, and inversions in which the hubs may have different with the consequent inclination in the architecture selected.

- Another procedure is to break a long note into a series of short ones which obey a determinate numerical pattern.

Chart 9

- Intermodulation of images: an image, let’s call it A, can transform another image (in this case B). The different parameters of both images can interrelate giving rise, in this way, to a great number of possibilities of new related forms.

Chart 10

- Reintroductions (substitutions, depending on circumstances): a determinate sequence of notes is introduced into the space of a long note, substituting the latter for the former ( the different colours of the material may or may not be respected).

Chart 11

- Inheritance: we can provide a sequence or a phrase with a range of attributes (phrasing, articulations, expressions…) which can later be preserved in any transformation whatsoever.

Chart 12

- Transformations with IFS techniques: this type of technique can be highly complex. Some of the techniques mentioned above can be carried out using IFS. Later we devote a chapter to the study of some of them.
