The Crimson String Quartet is a band of four stringed instruments - a cello, a viola, and two violins. The cello (played by Alyssa) plays very low notes. The viola (played by Alvin)plays low notes too, but higher than the cello. The violins (played by Audrey and Etienne) play the higher notes. They played some classical songs by Papa Haydn, Beethoven, and some pop songs too like "Here Comes the Sun" by the Beatles and the "Orange Blossom Special". Thank you CSQ for coming to our school to teach us about string quartets.
