Well, there aren't 76 trombones in this practice session, only 5. Still, it was a pleasant few moments I spent at Furman Park listening to the trombone section of the Warren High School band. Interesting how they all pointed toward the center to hear each other and get a better feel, or ear, for the contribution of the trombones to the sound of the band.
How did you practice your musical instrument? I used to go out by the pool and sit on the diving board to play my clarinet in quiet.
