Musical Form

Other aspects of music that can be manipulated to create musical organization are texture (dense or sparse, chordal or contrapuntal) and register (high or low pitch areas). In different ways, for example, the Russian-born composer Igor Stravinsky and the French American composer Edgard Varèse created musical structures by manipulating textures and blocks of sound. Complex mathematical relationships have been used by the Greek composer Yannis Xenakis and others as a basis for musical form. See also Improvisation.
