Momentform
Moment form called a musical composition technique that is particularly associated with the work of Karlheinz Stockhausen. A program written in moment fitting is as it were composed as a mosaic of moments; a torque is a " stand-alone ( quasi-) independent portion spaced apart from other sections through fractures. "
Explanation
The concept of moment form - and the name itself - go back to the composition contacts by Karlheinz Stockhausen ( 1958-60 )
In Stockhausen's terminology is a moment of 'any perceptible through a personal and distinctive characteristic form unit in a particular composition, " " One moment can - formally - a figure (individually ), a structure ( individually ) or a mixture of both; seen and in time it may be a state ( static) or a process (dynamic) or a combination of both. " " moments can thus, depending on the characteristics, arbitrarily long or short. "
In the formation of moments to musical works is a full line, a " narrative thread " intentionally avoided. The moments, which constitute such a composition are related to each other by a non-linear system proportions. If this proportion system exploits a predetermined amount of possibilities, it is called a closed form; if not, or if the series of proportions is not finite, then the form is open.
The moment the form is not necessarily avoid recognizable targeted processes. "They simply refuse to participate in a globally- directed narrative curve, which is obviously not their purpose. " In Stockhausen words such works have the property that they
Aim neither to the climax yet to prepared and therefore expected more Klimaxe back and do not represent the usual initiation, escalation, reconciliation and Abklingstadien in a related to the whole work time development curve; which immediately are rather intense and - constantly present the same - look for the level of continued ' main things ' endure to the end; where one has to expect a minimum or a maximum at every moment and can not predict development direction from what is present with certainty; have always already begun and so on indefinitely could go; in which either one of each present, or nothing at all; where nothing restless each one is now as a mere result of the above analysis and as a prelude to things to come that the hoped for, looked upon, but as a personal, independent, centered, which can bestehn for themselves; Forms in which a moment not bit of a time line, a moment does not have to be particles of a measured duration, but in which the focus on the now - on every now - makes quasi vertical cuts transversely penetrate a horizontal conception of time until the timelessness, I call eternity: An eternity that does not start at the end of time, but is reachable at any moment. I speak of musical forms in which apparently no attempt is made lower than the concept of time - more precisely, the concept of duration - to blow up, so, to overcome it. ... in such works beginning and final [ are ] open.
Secondary contacts can be found among the works that are particularly associated with the moment form, the slightly earlier composed Song of the Youths ( 1955-56 ), and the later works Carré (1960), moments ( 1962-64/69 ), mixture (1964 ), microphonic I ( 1964), microphonic II (1965 ) Tele Music ( 1967), mood (1968), and from the late work Saturday from light ( 1981-83 ), Michaelion of Wednesday from light, and joy (2005).
The concept of moment form is often associated with mobile or ( in Stockhausen's name) " ambiguous " forms of aleatoric been confused because the moments can be arranged differently in four of these compositions ( moments mixture, microphonic I and mood ). But various other works by Stockhausen have this mobility feature without falling into his category of moment form, for example piano piece XI ( 1956), chorus (1956 ), cycle (1959) and Sirius ( 1975-77 ).
Some works of others, both past and contemporary composers have been cited as examples of the moment form, such as István Anhalt, Earle Brown, Elliott Carter, Barney Childs, Roberto Gerhard, Michael Gielen, Hans Werner Henze, Charles Ives, Witold Lutoslawski, Olivier Messiaen, Morgan Powell, Roger Reynolds, Roger Sessions, Igor Stravinsky, Anton Webern, Stefan Wolpe, Yehuda Yannay and Frank Zappa.
