polytonality
There are several types: Tonal (In a key): This can be a major or minor key. Modal (In a mode) Atonal: No key, no tonic note. There are various other more complex types like twelve tonality, whole tonality and polytonality, but these are the main three types.
there are so many branches such as singing, playing, magement, bussiness, composition, research, folklore , Instrument making, orchestre and etc. However there are lots of methods and sub-branches in any kind of music such as Jazz, Bluse, Rock, Metal, classic and modern and contemprory music. If world music come in account then any country's music has its specific rule and it could be mentioned as as a branch.
The Impressionist period was from about 1860 to the early 1900s. Two famous composers were Debussy and Satie. The music is all about giving and IMPRESSION of an image or feeling. Nothing is clear cut, it's slightly 'fuzzy' like the impressionist paintings by Monet or Van Gogh. Modes were commonly used rather than the traditional diatonic scales. The whole-tone or pentatonic scales were also used. 7th chords were very common, with parallel chords adding to the impressionist style. You can also use 9ths, 11ths, and 13ths. Many pieces feature a dreamy mood which are helped by treble and the bass fitting together but not in a traditional way. The almost sound 'wrong' to the untrained ear, but it actually works. A good example of this is 'Claire de Lune' by Gabriel Fauré which I have actually performed (a beautiful piece).
the music is more explict and wierd.back then they didnt realky talk about sex and drugs and money all the time. they rapped about what was real. now all you hear about is gettin girls and having sex with them if you pay them and selling drugs to get money.
