In certain New Orleans music scenes, there is a special sound — a signal — that lets players know it's time to pick up their instruments and strike up the band.
"It's a bugle call, or a band call, to assemble," trumpeter Leroy Jones says.
"It's like: C'mon, rally," musician Matt Bell adds. "Come to the bandstand and be ready to do it. Let's go."
The four-note phrase, however, doesn't belong to musicians alone. Another common New Orleans species, the mockingbird, also produces the call.
