This work represents my own way in the search of new forms of organisation of the music material going further from the traditional ones. The idea that inspired me was the development of a human being (or any other kind of living creature) that evolves through the time who, at his end, is not the same since the beginning despite he keeps his essence. New elements are constantly introduced, but the essence remains in the organisation of the pitches and lengths. So, coherence stays throughout the development. (Antonio Velasco Polonio)

Composed in 2003, I premiered GEOMETRÍAS 1 in Barcelona in November 2004. I very well remember how enriching was the experience to participate in its composition process, testing the effects and clarifying some technical questions with the composer. Collaboration with composers is a matter of trust between creator and performer. Although I already had collaborated with composers during my time with SAX 3+1 Saxophone Quartet (1994-2013), this work means a lot to me. It is the first piece for baritone saxophone solo written for (and dedicated to) me.

All the elements in GEOMETRÍAS 1 appear progressively and replace each other, giving structure to the work. The only element that appears throughout the whole piece is the quarter of tones. This work is based on a melodic series with microtones that gives it a very special colour. Check here my quarter tones chart.

The indications of the score are clear, the notation is conventional and the reading is not difficult at all. The polyphonic part of GEOMETRÍAS 1 deserves a special mention, in my opinion. I think that it is very well done. The great variety of multiphonics of the final part of the work produce an interesting sonority due to subtle changes of timbers.

In 2015, Robert Sirvent (flute teacher of the Music Conservatory of Tarragona and visual artist) made a beautiful vídeo for this work, coincidint with the launch of my album Believer. Watch it!
