Edward Carroll's musical beginnings were inspired by a door-to-door trumpet salesman in Chicago nearly 30 years ago. The salesman's pitch worked pretty well: Today Carroll is the director of the New York Trumpet Ensemble. The 34-year-old trumpeter and his brassy group are coming to the University of Maryland, College Park, on Saturday at 8 p.m. to present "The Art of the Trumpet: 1600-1725." The all-baroque program will feature works by Vivaldi, Purcell and Bach, among others.

Carroll's directorial focus is on the trumpet's historical connections. His ensemble explores music from the periods when the instrument flourished -- the 17th, 18th and 20th centuries. Many of the compositions sound similar, he says, because the original court trumpet had no valves and only a limited number of notes. While his group remains faithful to the original compositions, they use the full capabilities of modern trumpets, which allow broader range and greater improvisational freedom. "Baroque music is 18th-century jazz," he says. "You improvise a lot."

The New York Trumpet Ensemble includes David Bilger, Scott Thornburg, Jeffrey Curnow, Thomas Bontrager and Washington native William Neil.

Tickets for the concert at the Center of Adult Education auditorium are $14 and $10 and are available at TICKETplace, Dale Music and the Center of Adult Education. For more information call 454-6534.

And on Friday at 3:30 p.m. in Tawes Recital Hall, Carroll will give a trumpet workshop on solo performance and technique. The workshop is free and open to the public. For further information, call 454-2501.
