The problem of differentiation of song melodies by their «national» belonging with the use of interval-metric characteristics was considered. An easily interpreted system of quantitative characteristics, which enables the formulation in terms of repetitions of national-specific features intrinsic to samples of the Russian, French, and American melodies is proposed. The most informative (in terms of classification) fragments of melodies were found.
