Akkord piano sheet music of popular songs

Akkord is a Soviet musical group (quartet), which actively worked on the stage in 1960-1988. A distinctive feature of the quartet was the maximum use of the capabilities of each participant's voice, purity of intonation, timbre balance (a harmonious combination of high and low voices). So, according to the quartet participants, a chord should sound full-bodied, euphonious even in dissonances. In each song performed, the quartet was recognizable, although it changed the nature of the sound, the color of the voices, the combination of timbres, generously using moving rhythmic and dynamic strokes.
