Variazioni e Frammenti su Aura, 1995 (in memory of Bruno Maderna) is a
composition for digital tape. The piece consists of variations and
computer elaborations of Aura's fragments, a composition for large
orchestra written by Bruno Maderna in 1970. The samples are excerpts from
an analogue recording of a live performance conducted by the composer. The
concepts of symmetry and specular structure, present also in Maderna's
original score, are the centerpiece of this composition. Techniques of
variation and sound fragmentation are employed in this piece. The
computational sound process, moreover, allows for variation and
fragmentation at the sound generation level. Fragments are short samples
taken from the original recording and presented as they are, or with
minimal changes. The fragments are pasted together as in an archaelogical
reconstruction. This reconstruction, however, is only one of multiple
possibilities and does not necessarily correspond with the original syntax
of the piece. Deformation of space and time is the focus of the
reconstruction. Variations, the basis of the syntactical macrocosmic
structure of the piece, are also employed in the generation of each
individual phoneme. This structure is applied to each element. All the
variables introduced, both microstructural and macrostructural, contribute
to the generation and modification of the sound structure as well as the
score itself. Variations and fragments are merged by means of the process
of convolution.
