Formed by Antonio Rosales (bass clarinet), Juan José García (doublebass), and José Luis Hurtado (piano), LOW FREQUENCY TRIO is one of the few ensembles in the world that plays music that was exclusively composed for them. Its members are highly active in the international contemporary music scene and as a trio they have performed and held residencies at the Centro Mexicano para la Música y las Artes Sonoras, Centro de las Artes of San Luis Potosí, Conservatorio de las Rosas in Morelia, Festival Ecos y Sonidos, Festival Internacional Cervantino, the Museo Universitario de Arte Contemporáneo MUAC UNAM, and the Palacio de Bellas Artes in Mexico, the University of Texas and the University of New Mexico in the U.S., as well as the Universidad Nacional de Quilmes and the Conservatorio Manuel de Falla in Argentina. Since its foundation in 2016, LF3 has collaborated with more than 25 young and established composers in the creation and performance of fresh and innovative new works for this unique instrumentation which collective sound is yet to be discovered and repertoire until now was practically nonexistent.


For fourth year in a row, Low Frequency Generator is the yearly platform that seeks new, fresh, and innovative works for Low Frequency Trio, a bass clarinet, double bass, and piano music ensemble based in Mexico City.


Open to composers of any age and nationality.

Proposals must include the three instruments mentioned above. Proposals for solo pieces, duos, or other types of clarinets than bass clarinet will not be considered.

Proposals can incorporate fixed electronics and/or amplification.

There is no entry fee.


It is essential for Low Frequency Trio to be part of the creative process through the constant interaction between composer and ensemble. For this reason, we are not looking for finished works.

Send us a score of a work in progress of a minute and a half maximum duration.

The score must briefly but eloquently show the elements, aspects, and other concepts, to be developed throughout the piece.

The score can be handwritten or done with a music notation software.

Our selection will be based on the score, the idea, and its potential only. With the exception of performance notes, there is no need to include any other type of explanation or verbal description of the work.

For those works that will include electronics, a short sample of the sounds, textures, or trajectories planned to be used will be greatly useful. This however, is not required.
