" The software opens up the possibility that brass instruments could be customized more closely to the needs of individual players in the future -- catering more closely to the differing needs of jazz, classical and other players all over the world."
Please. This has been the case for years! As someone who has played a brass instrument for 18 years, I can authoritatively tell you that there are already significant differences between a trombone made for jazz music, classical music, and beginning players, to list only a few categories. As far as "customized," Edwards Trombones http://www.edwards-instruments.com/index.shtml can heavily customize an instrument to the player - having played one, I can tell you specifically how my embouchure differed from the owner of the horn. Leadpipe, bell flare, material, even the finish can be customized and predictably constructed to match the player. This is not a "new" concept based on a history professor with a computer - this is an extension of the tradition and history of instrument-making.

Geez you nitwit - it's the equivalent of Libraries of Congress per parsec!
The hardest part of climbing the ladder of success is getting through the crowd at the bottom.
