Overview of Edgard Varèse’s Density 21.5 for Unaccompanied Flute

Density of 21.5 The density of 21.5 Edgard Varèse is suitable for unaccompanied flutes designed in 1936 (revised in 1944) for the premiere of his new platinum flute at the request of George Barrere. Inspired by the ability of the flute, Varese showed off the full range of the sound of platinum instruments and tried to explore their brain's abilities. Density is a monaural work characterized by extreme dynamics, angular motive, tone change and complex rhythm. Within the measuring range of 61, Varèse makes full use of the full range of sound and color of the flute, allowing nearly all pitch of the instrument.

John Cage, Harry Partch, Edgard Varèse, they are famous composers who made several music pieces using non-traditional instruments. Since the beginning of the 20th century, Ionization of EdgardVarèse probably used air raid sirens (among other things) and composers began asking percussionists to 'find' objects to invent the objects to produce the sound and texture they wanted . In the latter part of the 20th century, this instrument became popular in contemporary percussion ensemble music and pop music such as performances other than Broadway, Stomp.

Several composers are often considered to be bold and impressive builders of the official "architecture" structure. EdgardVarèse and Iannis Xenakis soon came to mind. Indeed, Xenakis is known as an architect and composer, and Varèse proves his strong interest in the structure of nature. I am not affected by natural phenomena and physical phenomena like composers. When I was a boy, I was deeply impressed with the quality and characteristics of the granite I found in Burgundy. They do not use cement and each stone must interact with other stones. So I am always concerned with this stone thing and this purely structural building ... all of these are an integral part of my thinking.

In the 1920s, some composers were influenced by the individuals of the Surrealist and Surrealist movement. These include Bohuslav Martinů, AndréSouris, Erik Satie and Edgard Varèse who say that his work Arcana comes from a series of dreams. In particular, Surris is related to this movement. He has a long history with Magritte and plays Adieu Marie in Paul Nuger's publication. Germaine Tailleferre of the French orchestra Les Six has several works which can be regarded as surreal inspiration such as Balleter Paris-Magie (Lise Deharme) of 1948, OperaLaPetiteSirène (Philippe Soupault's book), LeMaitre (EugèneIonesco) I have written. Tailleferre also writes popular songs for Henri Jeanson's wife Claude Martin, portrait painted by Magritte in the 1930s.
