Sebastian plays drums for percussion in an orchestra. He sits next to the brass section where four people play trombone, two play trumpet, and one plays a French horn. In front of them are the strings section with three violinists, a cellist, and a contrabassist. Next to the strings are a trio of clarinets and a quartet of flute players in the woodwinds section. The maestro conducts them all. How many people are in the orchestra?
Sebastian in the percussion section makes <<1=1>>1 person.
The brass section has 4 + 2 + 1 = <<4+2+1=7>>7 people.
The strings section has 3 + 1 + 1 = <<3+1+1=5>>5 people.
The woodwinds section has 3 + 4 = <<3+4=7>>7 people.
The maestro is 1 person.
Thus, the orchestra has 1 + 7 + 5 + 7 + 1 = <<1+7+5+7+1=21>>21 people in it.
