Performance of musical scale in traditional vocal homophony: Lithuanian examples

Abstract

Acoustical measurements of pitches in a dozen songs exemplifying the Lithuanian traditional vocal homophony were carried out. Several phenomena were revealed. First, the entire scales experience gradual transposition (rise) from the beginning to the end of the song performances. Second, the transposition is supplemented with the gradual shrinking of the musical scales (the intervals become narrower). Third, the intonations of the scale degrees are dynamic, i.e. they depend on the musical (both melodic and harmonic) contexts. Fourth, the versions of musical scales work as certain markers for the idiolects (further studies could show if this might be extrapolated to the realm of dialects). All these insights raise issues about the perceptual qualities of the musical scales and their manifestations in the performance.
