The range of original literature for guitar duo is limited; here Rafael Andia’s Canciones flamenco antiguas and Joaquín Rodrigo’s Tonadilla are pieces that were originally written for this instrumentation. Therefore it was necessary that for such a Spanish program we find pieces with other instrumentations that could be adapted for guitar duo. Thus we came across Manuel de Falla’s orchestral music which can be excellently set on guitar, the idiomatic instrument of Spanish music—especially since the orchestration of pieces we were particularly careful to preserve the significant and characteristic voices and elements of the pieces and to make adjustments für specific guitar techniques and timbres. The basis of our work is always the orchestral score and not the piano score because of the frequent omission of important voices in the latter. The duo music arises from the accompanying voices on both guitars.
