The type of error in the given sentence above is the use of the appropriate verb. The verb used in the sentence is "play" which is wrong because it refers to the instruments. It is not the instruments that do the action "play", but rather, the instruments are being played. The correct sentence would be: Symphony is where many kinds of instruments are being played for a long piece of classical music.
