This way of building a piece of music was used by almost every composer from the mid 18th century onwards – well into the 20th century. It gives scope for a very dramatic piece. Of course, composers sometime use it differently. There is often a sense of development during the whole piece, not just during the so-called “development section”. The first movement of Beethoven’s Fifth Symphony spends all the time developing the famous idea heard at the beginning: the first four notes (short-short-short-long). Even the other three movements carry on developing this idea.
