Sonata for organ

This sonata as been composed for the 29 Wuppertaler Orgeltage.

The first movement, Tema e variazioni, is a set of short variations on two folk songs: Nòter de Bèrghem (Us from Bergamo) and Sur le pont d’Avignon. The variations are introduced, and concluded, by a short rhapsody were the two themes are, in part, quoted.

The second movement, Cantabile, is composed utilizing as a model the Cantilene by J. G. Rheinberger, and a motivical frame extract from the Premier Choral by C. Franck. The Adagio marking in the score also means that the piece had to be intended in 8. The Passacaglia, in four, is based on a bass line coming out from my own Trio “Chanson de Jour” op. 23 n°1 for violin, cello and piano.

The setting of elaborations upon the bass is opened by a short introduction end then it is developed in a more complicated and visionary transfiguration of the thematic material, on trying to explore the harmoncal possibilities of the theme.

The last transformation of the bass line is created utilizing a little quotation of one of the last variations of the Passacaglia BWV 582. The very short coda who conclude the whole work, only one bar, remind to the true soul of the Sonata: the recreatio chordis.
