"An orchestra is a musical ensemble of mixed instruments under the direction of a conductor. The conductor makes sure all of the members of the orchestra are playing together."
"In the orchestra you will find four families of instruments: strings, woodwinds, brass, and percussion."
"Sometimes there are smaller orchestras that only consist of string instruments, they are called a string orchestra."
"You will be joining an orchestra named the Lexington Philharmonic Orchestra. Let's meet the different families in your orchestra."
