The article deals with an issue of interfacing meditative and expressive principles in music that is urgent in contemporary art. The semantic range of the meditative principle can vary, but mostly it is interpreted in the philosophical and religious senses. In the music of the XX-XXI centuries the meditative principle was manifested itself as a particular type of thinking: from soft contemplation, static - to intense concentration of thought or feeling, when creating space for the dynamic expressive principle. At a certain conception they move into each other in a flexible way, penetrate into music, which supports not only religious values, but embodies the psychological stress and diverse meanings that combine the external statics and deep dynamics. The interaction of the meditative and expressive principles in music is revealed on the basis of the works by A. Schnitke and V. Artemov.
