After 1950? s flute music and special effects

In order to explain alternation in flute music of 20th Century, we have to examine he changes in 19th Century and the creations of this period composers. First of all art movements have major impact in these music developments.In the period after World War II, ?Total Serialism? movement had emerged. After 1950, this complex pattern yield its place to ?Aleatori? movement in which all elements of the music left to will of composer during the performance. With this movement, free writing style, open form, closed form and graphical notation techniques are developed.For Boulez, Berio, Stockhausen, Nono and Cage, important composers of 1945-1970 period, term of ?avangard? has been used, meaning that innovative and performing the unperformed, and this period is known as ?avangard? period. At the end of 1950, Composers like Penderecki and Ligeti foregrounded the pattern instead of tune. They wrote verses having increasing and decreasing density in notes in terms of rhythm in the partitions of instruments. In mid 1950, a Greek composer added mathematical lines to notation. He used mathematical equations in notation.Afterwards, composers tend to electronic music. Idea of changing music by processing with electronic instrument becomes more widespread. First of all, device called ?telharmonium?, generating artificial sound by electrical generators. Then Maurice Martenot created device called ?Martenot Wave? which looks like an electronic keyboard.Music showed similar and parallel development with electronic technology. At the end of 20th Century, computer began to use for composing music. Before that, electronic music has to be recorded in tapes to be fixed. But nowadays, with the help of computers sound could easily be processed after it is recorded.New quests in 20th Century have procreated the desire to find sound colours and new techniques. Noisy percussion sounds are used frequently and especially instruments have been played the highest or lowest pitch. Unusual playing techniques are become normal. Breath, speed and use of dynamics increased excessively and new findings like frog tongue, micro tones, whispering sounds and other unusual sounds began to be used. At the end, electronic and recording technology become more interesting to composers it does not take much time that they combined these elements as ?Electro Acoustic?.
