This is Scientific American's 60-Second Science,I'm Christopher Intagliata,got a minute?


Benny Goodman earned his title,the king of swing as a virtuoso1 of the clarinet,but now a computer in upstate New York has learned to rip him off.Researchers at the university of Rochester recently unveiled their computerized clarinet which you're hearing.It listens to a clarinet solo and figures out how hard the player was blowing,his lip pressure on the mouthpiece and his finger position,the virtual clarinet  player uses this information to reproduce the solo on its virtual clarinet,a synthesizer based on the physics of the clarinet.To design the synthesizer,the team played a real clarinet while measuring physical changes like the reeds vibration,and the pressure of the air column inside.They modeled these measurements with equations to create the virtual clarinet. An audio file of the solo reproduced by the virtual player is a thousand times smaller than the original as an MP3.But it still doesn't sound as good as Benny.The simulation doesn't swing as well as the king we have.But future music could come from various synthetic2 instruments modeled on performances of the masters.


Thanks for the minute for Scientific American's 60-Second Science,I'm Christopher Intagliata.
