Changes in 20th Century Music that affected Symphonies and Symphony Writers and Project the Future for 21st-century Symphonies

(My Opinion in) changes in 20^th century music and how that affected symphonies and symphony writers. Then, project the future for 21^st-century symphonies (styles, timbres, forms, venues, audiences, media, and so forth)

20^th century classical music is also known as Modern classical music. In early 20^th century the style of composition definitely changed from romantic period. We could found new words such as Atonal, Serialism, Chance music, Experimental music. Composers were more willing to experiment with new music forms or reinvent music forms of the past. They also took advantage of the resources and technology that were available to them. Composers had more creative freedom. Composers in 20^th century try to diverse reactions in challenging older categories of music, innovations that lead to new ways of organizing and approaching harmonic, melodic, audio and rhythmic aspects of music, and changes in aesthetic worldviews in close relation to the larger identifiable period of modernism in the arts of the time. Could say this is also innovation in music.
                The change of the styles and techniques that are affected symphonies and symphony writers by their way of composing that they try to equal all the sound by twelve-tone technique (created by Arnold Schoenberg) but the sound that occur from this kind of composing is not sound that simple and could say that it’s hard to listening to or to appreciate with the sound like the past because the composer want to share new ideas of music. Another thing that changes from the past is the smaller size of orchestra if compare to the past because the value of money had change after world war there was depression. Definitely no one interested to attend live performance and no one have money to pay for concerts. People need to keep money for their living. So composers have to decrease the number of instrument in their composition so they can hire musicians to perform their own composition for example in Anton Webern’s Symphony (op. 21) composed in 1927. That has 2 movements but has only 9 minutes long. It’s short but has many ideas in this symphony such as complex canons, final six pitches are a transposed retrograde of its first six pitches of the matrix, seven variations in the 2^nd movement.
                If I could project the future for 21^st-century symphonies and also all kind of music, I think there won’t be the composer or musician that their career is only do the music stuff for their living. Those could be doctor or businessman that can be musician and composer. Because music will cannot be occupation anymore. People in society think that music is just easy thing to find and should be free for them. They can do illegal things by download free MP3 from internet or event watch free music video and concerts from Youtube website.  The value of music will decrease. Nobody interesting that how musicians or composers will live their live so people who love music need to do music as hobby and just share their idea to free media. This also affected symphonies. No one will listen to long music because they need to keep time to do the job for capitalism life style. No time to appreciate art but keep working and concentrating for factory system and their boss. The forms, styles, timbres will getting shorter and less instrument (That’s already happened in Webern’s symphony already; short symphony). Instead of using musical instruments they could use others equipments such as watering can or spoon to be a part of compositions. For example, Drip Music by George Brecht that can expand this idea of composing to be a dripping watering can symphony. In the style of music in 21^st century could be easier to understand and maybe have no form of music and also try to escape from the form in the past.
