Kammermusik has three conceptual axes. One is idiomatic, since the German language gives to this word the sense of unit that the Chamber Music must have independently of the diversity of sounds and consonances of the instruments that take part in a work. The second is intimate and goes partly also bound to the Germanic language since has to do with my own personal history, that it is crossed by the Germanic culture from my childhood. Third, it has to do with the search of a format absolutely differentiated from which it is understood by a solo disc: the guitar, it follows appears like central axis, since it forms part of all and each one of diverse instrumental formation that conforms this work, giving this way a protagonist hierarchy same but thanks to the different approaches from which is approached it in each work.
