In music unified field is often used to refer to the "unity of musical space" created by the free use of melodic as harmonic and harmonic as melodic material.
The technique is most associated with the twelve-tone technique, created by its "total thematicism" where a tone-row (melody) generates all (harmonic) material. It was also used by Alexander Scriabin, though from a diametrically opposed direction, created by his use of extremely slow harmonic rhythm which eventually led to his use of unordered pitch-class sets, usually hexachords (of six pitches) as harmony from which melody may also be created. (Samson 1977)
It may also be observed in Igor Stravinsky's Russian period, such as in Les Noces, derived from his use of folk melodies as generating material and influenced by shorter pieces by Claude Debussy, such as Voiles, and Modest Mussorgsky. Bela Bartok's Bagatelles, and several of Alfredo Casella's Nine Piano Pieces such as No. 4 "In Modo Burlesco" the close intervallic relationship between motive and chord creates or justifies the great harmonic dissonance. (Samson 1977)
In physics, unifiedfield theory is an attempt to unify all the fundamental forces and the interactions between elementary particles into a single theoretical framework.
This unified theory was governed by the exchange of four particles: the photon for electromagnetic interactions, and a neutral Z particle and two charged W particles for weak interaction.
The unifiedfield theory must be consistent, explain all previously known aspects of gravity on a large scale, and of quantum mechanics on the subatomic level, in a single framework while making new and falsifiable predictions.
