Answer:the answer is B
Explanation:it changes by the time period
<span> <span> A symphony is a symphony. Beethoven's 3rd and 5th symphonies certainly influenced other composers, but symphonic structure itself hasn't been redefined. Symphonie Fantastique is a symphony in name only; likewise the Rustic Wedding Symphony by Karl Goldmark - very pleasing music, but not really symphonic. César Franck included a cor anglais in his D minor symphony, and one critic remarked that it wasn't really a symphony *because* a cor anglais was included. Adding a chorus and/or vocal soloists doesn't alter symphonic form.
