Yamaha high-pitched trumpets feature brilliant tone with crisp clear attacks and excellent control in the high register. Though originally used primarily for Baroque music, they are increasingly used by solo and orchestral players for security with difficult high passages as well as for the clarity and lyrical qualities of their sound. The 9635 features a heavyweight bell for the rich full sound of a big trumpet, yet with easy control in high registers. It comes with two bells and sets of slides to convert it to either E or Eb which makes it especially suitable for both Hummel and Haydn concertos.
