Cartesius Cantus
Cartesius Cantus is a piano cycle of 24 compositions, divided into six parts. In each part there are four compositions inspired from a specific ‘Cantus’ as follows: Albanian Cantus, Gregorian Cantus, Cantus della Natura, Cantus del Mundo, Cantus Homáge and Albanian Polyphony. Peçi uses the Cartesian Coordinate System to achieve a rhythmic pulsation from three basic values (1/8, 1/16, 1/32), using them in different combinations. It was exactly in this cycle that for the first time he managed to combine mathematical methods with singing styles, attempting to attain new sound expressions and a balance between rationality and emotions.
Cartesius Cantus No. 1
This piece has the subtitle Pluie lunaire (Moon Rain) and it represents rays of moonlight interrupted by the rain, a melody represented by colourful dissonant chords. The melody is characterised by a C sharp in Phrygian Mode, which is the axis of the modus in both directions, up from the right hand, and down to the left. Peçi uses the Seventh interval and its inversions, which he also calls it as “Oi-interval”, as a common Albanian element in his music.
The use of this interval is not limited only in the building of the melody, but also in the chord structure. There is an interesting fusion of three elements in this composition: the melody, the harmony and the mathematical pulsation.
Cartesius Cantus no. 12,
This piece bearing the subtitle Cyclone structure, is dedicated to the subject of global warming, which is common in Peçi’s work. Based on this topic, he wrote his Plantears, using Polygravité CC2 for the first time as his compositional logo. The cyclone in the piece is represented by an ostinato, based in the lower piano register. In the cyclone, flying objects are personified, represented by dissonant chords. It is particularly interesting to observe the regularity of the rotating cyclone and the irregular pulsation of 'flying objects' (the dissonant chords). Peçi used a Carouselle structure - his own technique, meaning he created several layers (five in this piece), in which the melody or the flying object rotates. In the base, there is also a citation of the Albanian Mourning Song “Ditë e zezë” (Dark Day). The sounds in this song give the composition an even more dramatic feeling.
Espace Triste
This melodyis based on an original Peçi’s motif used in the Canadian movie soundtrack Woman Without Wings in 2002. Later, in 2004, Peçi rewrote this part for two cellos, making it a dialogue, and dedicated it to Bledar Zajmi. The main motive and the music lines, which came later on, are rich in colors and ornamentations, as a typical inspiration from Northern Albania music. The sorrowful music communicates the feeling of hard life in the Albanian mountains.
