Errata: 1st movement: quarter note = 152
Tripartita, op. 12 was written between 1st and 10th October, 1955. Three movements - schnell-langsam-schnell - , based on variable metre as a constructional principle. In the 1st movement, block-like structures dominate, arioso elements with short motifs dominate the 2nd movement. The almost completely unisono, toccata-like finale rounds the work off with a virtuoso flourish.
Hummel composed the Tripartita for Organ in 1955. It consists of
three movements: Ostinato, Fantasia and Toccata.

The very compact "Tripartita"
has a lively opening with a harmonically-based idea, spread out syllabically,
interrupted by rests, over a markedly leading pedal. The means of formal construction
is the linear bass; this adds to a triad motif further intervals, so that the
planned total range of intervals is achieved after twenty-one bars. Boris Blacher's
variable metre technique comes to mind. The slow middle movement consists of a
combination of threefold thematic material. If in the opening harmonic colour
prevailed, then it is now above all the sumptuously-delineated melodic contour
which dominates. With multifarious substitutions and inversions, constantly new
perspectives of the same idea are revealed. The third movement is conceived as
fast passage-work with repeated notes and octave displacements on the manuals,
maintained unisono throughout except for the close. This new work is captivating
in its unsulliedly fresh power of invention. The formal principles are thoroughly
individual and use no worn-out standard patterns; effects in sonority, sometimes
extremely astringent, are applied with such economy that one immediately believes
on first hearing in their musical necessity.
