An orchestra is a large group of musicians who play together, typically consisting of strings, woodwinds, brass, and percussion instruments. The musicians are usually led by a conductor, who helps coordinate their performance and interpret the music. Orchestras can perform a wide range of music, from classical symphonies to contemporary film scores. Orchestras can vary in size and composition. A full symphony orchestra often includes over 100 musicians, while smaller ensembles, like chamber orchestras, may have as few as 10 to 30 players. Famous orchestras, such as the Berlin Philharmonic and the New York Philharmonic, are known for their exceptional performances and contributions to the world of music.
