Pere Valls i Duran va néixer a Sabadell (Barcelona) l’any 1869 i va morir a la capital catalana el 1935. Va destacar com a contrabaixista i com a compositor així com per la seva tasca com a pedagog del contrabaix. Va iniciar els estudis de música a Sabadell, però més endavant es va traslladar a Barcelona per ampliar-los. Als divuit anys, ja amb un bon domini del contrabaix, va viatjar a la República Argentina i es va establir a Buenos Aires on va formar part de diferents orquestres. A Buenos Aires va poder ampliar els seus estudis d’harmonia i de contrapunt, així com els de contrabaix amb José Roveda, deixeble directe del gran contrabaixista italià Giovanni Bottessini. L’experiència que allà va adquirir tan amb el repertori simfònic com en l’operístic va ser decisiva en la seva carrera. L’etapa americana va acabar l’any 1892 quan, per raons familiars, va haver de tornar a Catalunya.
Aquell mateix any es va instal·lar a Barcelona i, durant els següents 30 anys, va ser un dels artistes més destacats del panorama musical català pel seu paper rellevant en quatre facetes: en primer lloc, com a intèrpret —va formar part de les millors orquestres de l’època, com l’Orquestra Pau Casals, la Banda Municipal de Barcelona o l’Orquestra del Gran Teatre del Liceu—; en segon lloc, com a professor de contrabaix —va ser professor del Conservatori de Música del Liceu durant més de vint anys i per les seves classes van passar la major part dels instrumentistes de contrabaix del país, a part de ser autor d’un Mètode per a Contrabaix deutor de l’escola de Bottessini—; en tercer lloc, com a dinamitzador musical —amb la participació activa en diferents associacions musicals com la Unió de Músics de Catalunya, l’Associació Wagneriana de Barcelona o l’Associació Obrera de Concerts—; i en quart lloc, com a compositor.
Com a compositor Pere Valls va ser autor de més de cinquanta obres per a diverses formacions, però entre totes elles destaquen les dedicades al contrabaix. D’entre les seves obres per a contrabaix i piano destaquem la Suite Andaluza (1918) en quatre moviments —obra que actualment és de repertori en diverses escoles europees de contrabaix com per exemple a la Càtedra "Reina Sofía" de Madrid—les tres Fantasies per a contrabaix i orquestra (compostes entre 1894 i 1917) —una d’elles d’homenatge a Bottessini—, el Gran concierto obligado para contrabajo (1906), la Fantasía andante con variaciones, la Gran introducción y Tarantella, el Tema con variaciones para contrabajo, la Tarantella-concierto de contrabajo(1893) o la Romanza para Contrabajo y piano, obra que —en la seva transcripció per a violoncel— va ser estrenada pel mateix Pau Casals. El seu catàleg es completa amb obres per a orquestra, per a piano, per a grups de cambra, per a cobla, per a banda, per a instruments solistes, per a orquestra de ball i, fins i tot, una sarsuela.

Pere Valls i Duran was born in Sabadell (Barcelona) in the year 1869, and died in the Catalan capital in 1935. He was an outstanding double-bass player and composer and an excellent double-bass teacher. He began his musical studies in Sabadell, but later moved to Barcelona to extend them. At the age of eighteen, already with a good command of the double bass, he travelled to the Republic of Argentina, where he established himself in Buenos Aires, and formed part of several orchestras. There, he was able to extend his studies of harmony and counterpoint, as well as the double bass, with José Roveda, pupil of the great Italian double bass player Giovanni Bottessini. The experience he gained in Buenos Aires, both with symphonic and operatic repertoires, was decisive in his career. The American phase ended in 1892 when, due to family circumstances, he had to return to Catalonia.
That same year he settled in Barcelona and, throughout the following 30 years, he was one of the most outstanding artists on the Catalan music scene, because of the significant roles he played in four areas: in the first place, as an performer - he was part of the best orchestras of the time, such as the Orchestra Pau Casals, Barcelona’s City Band and the Orchestra of the Gran Teatre del Liceu; secondly, as a double bass teacher - he was a teacher at the Liceu Conservatoire for more than 20 years, and the majority of the country’s double bass instrumentalists passed through his classes. In addition, he was the author of a Method for the Double Bass, indebted to the Bottessini School; thirdly, through his work in promoting music, by actively participating in different musical associations like the Musicians’ Union of Catalonia, the Barcelona Wagnerian Association or the Workers’ Concert Association; and, fourthly, as a composer.
As a composer, Pere Valls was the author of more than fifty works for various groups, but, of all of them, those for the double bass are outstanding. From among his works for the double bass and piano, we highlight the Andalusian Suite (1918) in four movements. It is a work which is currently included in the repertoire of several European double bass schools, such as Madrid’s Reina Sofia department. Other remarkable works are the three Fantasias for double bass and orchestra (written between 1894 and 1917), one of which is a tribute to Bottessini; the Grand obligatory concerto for double bass (1906), the "Fantasia andante" with variations, the Grand Introduction and Tarantella, the Theme with variations for the double bass, the Tarantella-concerto for double bass(1893) and the Romance for double bass and piano, a work which - in its transcription for the cello - was played for the first time by Pau Casals himself. His catalogue is completed with works for orchestras, piano, chamber orchestras, the "cobla" (a wind orchestra popular in Catalonia), for bands, solo instruments, dance bands and, finally, a "zarzuela" (Spanish operetta).
