Claudi Meneghin: Chaconna in G=, ‘La Padana’ ou ‘la septimala’
A Chaconne for chamber organ in the 31-tet approximation of subminor
G. Septimal minor thirds ‘G-Bb;’ mostly characterise the tonality of
this neobaroque piece, as well as plenty of harmonic seventh
intervals. We have five modules of four variations each, on the same
eight-measure xenharmonic ground bass. In particular measures 4-5-6
feature the chromatic descending scale G G; F# F E Eb; D| D. All
variations show quite similar harmonies in their first four measures
but two different types in their last four ones. We refer to them as
types ’1′ and ’2′. Type ’1′ is ancient flavoured, type ’2′ is much
more dissonant. As to these types, the first four modules have the
structure 1-2-2-1, whereas the last one has the structure 1-1-1-1.
Also, the last two variations are little fugues, supported by the
usual ground bass.
Tuning system used: 31-TET
