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.
Tchaikovsky wrote four orchestral suites in the period between his Fourth and Fifth Symphonies. The first three are original music, while the fourth, subtitled Mozartiana, consists of arrangements of music by Mozart.
