The Three Main Categories of Drugs. Some drugs due to certain factors that change their characteristics, may cause them to fall under different categories at different times. For example, even though Cannabis is considered a depressant, in high enough doses it can also be a hallucinogen. The three main categories were constructed based on similarities that certain drugs share; however, there are many differences that these drugs have also.
A rhythm is very identifiable, even if the composer changes all the notes and the harmonies. Because of this, Beethoven use the rhythm of the Fate motif loads of times all throughout the 5th symphony, to tie it together. The Fifth symphony, like all symphonies at the time, is in four movements... 1  1st Movement, Sonata. 2  The powerful first movement opens with the Fate motif, which runs through it in one way or another throughout.
Answers. 1  A symphony orchestra is a BIG band, ranging anywhere from 60 to 150 players, depending on what composition they are playing. A symphony can range from 40 minutes ( works by Joseph Haydn and Wolfgang Mozart) to over an hour and a half ( Gustav Mahler and Anton Bruckner). Other pieces, also played by a symphony orchestra, but not necessarily symphonies, can also last from a few minutes up to an hour.
