"Jimmy Giuffre used to play mostly in the lower register on the clarinet and rarely went above the break—the end of the first register. We used to kid him by saying, 'When are you going to play above the break?,' which is a big step when you're learning the clarinet. Jimmy laughed and said, 'I’m working my way up.' He loved that soft sound."
