Ernesto Aurignac has written more than 150 pieces for various musical ensembles, premiered by the Gran Canaria Philharmonic Orchestra, Spanish Brass, Barcelona Municipal Band, Bilbao Simphonic Band, Vitoria-Gasteiz Municipal Band, and soloists such as Manuel Martínez of "Clarinet Players Barcelona," harmonica player Antonio Serrano, saxophonists Daniel Molina and Marta Romero, U Circle Breakers, Sedajazz Bigband, Clasijazz Bigband, Musikene Jazz Big Band, and several commissions for different editions of the FIAS in Madrid and for the Mano a Mano in Buñol 2023.
The sound of his music is a fusion of his influences and life experiences. Classical and jazz music provided him with a broad harmonic-rhythmic-melodic perspective that he uses in the search for his sonic identity, resulting in a unique and recognizable compositional sound.
