Musica para dos megainstrumentos y grupo de camara (Music for two Megainstruments
and Chamber Ensemble) is a six-section piece written for two violins
(treated as a megaviolin), two flutes (treated as a megaflute) and chamber
ensemble. Both the form and the different tempi of the piece are determined by the
interaction of the two mega-instruments and the ensemble.
The piece is an original contribution in its concept and use of the megainstruments.
A mega-instrument is composed by two single instruments of the same
kind. The main function of the mega-instrument is that of expanding the technical
possibilities of the individual instruments that constitute it, as well as creating new
possibilities, while keeping, at the same time, the specific characteristics or
"personality" of the original instruments. In the Primer ensamble and Segundo
ensamble sections the two mega-instruments are incorporated into the ensemble
and treated as four individual instruments.
The basic pitch structure of the piece is represented by SC [014], which is
further organized in a six-note scale that is a member of SC [014589]. The six-note
scale (used in the piece as an unordered set) and its three available transpositions
create a universe of four pitch regions with two different modulation levels to
connect them. Pitch Regions are also used simultaneously in the piece. This
procedure (that I have called a multi region) includes harmonic and/or melodic
intervals that are not available within single pitch regions.
The piece could be defined as atonal or without pitch centers. It is
characterized by an interaction of the tempered system and the pitch continuum
(microtones and glissandi).
