A turning point in classical music. Take a joyous journey to where it all began – Italy – the birthplace of the orchestra and the Baroque classical era. Widely considered to be the one of the most influential periods for modern western music, the Baroque style is marked by fuller and more complex musical compositions, including multiple independent melody lines, performed simultaneously by different instruments, and often incorporating voices, just as we see in modern symphonic presentations.

An Intimate Evening of Chamber Music

San Bernardino Valley College Auditorium

An original repertoire for trombone and piano, ranging
between the eighteenth and twentieth centuries. A dialogue between two solo instruments, each with its own particular aroma, which go at times to merge in an alternation of delicate timbres and broad, marked sonorities, of rhythmic pulsation and expressive warmth.
While the role of the piano as a solo instrument is universally
known and recognized, that of the member of the family
of brass is much less so. However, there is a specific literature
combining the two instruments since the 18th century. Reviewing styles and languages from different eras, the program aims to analyze this repertoire up to the height of the twentieth century. The alternation between pieces for trombone and piano and pieces in which the two instruments are separated composes this interesting mosaic of sounds, colors and... flavors.
