Designed for Don Harwood, bass trombonist of the New York Philharmonic, this mouthpiece's goal is to make his job easier. The Don Harwood Signature Series mouthpiece accomplishes this task by projecting the clear independent voice of the orchestral bass trombone while locking in on octaves with the tuba, and supporting the trombone section of the orchestra. To accomplish this task the mouthpiece is designed with a medium cup and balanced backbore and throat enabling the Don Harwood Signature Series mouthpiece to project. Additionally, these features make the Don Harwood Signature a versatile bass trombone mouthpiece capable of supporting any orchestral section.
