CHARAKTERISTICKÉ TÓNOVÉ MNOŽINY AKO ZJEDNOCUJÚCI ELEMENT KLAVÍRNYCH IMPRESIÍ TADEÁŠA SALVU

The set of miniatures Piano Impressions by Tadeáš Salva (1937 – 1995) was composed during a short period of the composer’s inspiration by Schönberg’s atonality. The presented paper examines the harmonic frame of the work based on set analysis. The analysis demonstrated the use of specific pitch-class sets, which the composer developed and applied in a variety of vertical and horizontal forms. Pc-sets 3-5, 3-8 and 3-9 are used in the work both as constituents of higher supersets and also as separate harmonic units, in their own way substituting traditional consonant triads. Together with the set 2-1 (semitone interval) and 3-11 (major/minor triad) they form the harmonic basis of the work. The study deals with the application of their specific forms (transposition and inversion) and examines the validity of the hypothesis about their unifying function of the composition as a cycle.
