The CHI Brass Arnold Jacobs 1 Tuba Mouthpiece pays tribute to one of the most influential figures in brass pedagogy and orchestral performance. Designed to reflect Arnold Jacobs' emphasis on musical communication, efficient airflow, and beautiful sound production, this mouthpiece offers remarkable versatility and tonal richness. Based on his first Helleberg mouthpiece he got as student at the Curtis Institute of Music and used in numerous performances with Philadelphia, Indianapolis, Pittsburgh and Chicago symphonies we have added some weight to the shell and modernized the shank options for today's players.
Whether performing orchestral literature, chamber music, or solo repertoire, the Arnold Jacobs 1 encourages a natural, resonant sound and effortless musical expression.
Arnold Jacobs' teaching and performance philosophy continues to influence brass players worldwide. This mouthpiece honors that legacy by combining tonal beauty, efficiency, and comfort into a design suitable for today's performers.
