Resultant Clusters and Chords

The section analysed shows a total horizontal (contrapuntic) layout, however it is interesting to investigate on the resulting chords and clusters.

Individual part motions are expressly set very fast and asynchronous in rhythms. The music notated in 30#30 time signature at a tempo indicated half-note at 30 BPM so one bar lasts one second. Bars are also divided in two halves by a vertical dotted line to facilitate the reading of the music.

Except for the previous double-basses cluster attack which occurs four bars before (at bar 40) and sustained tutta la forza, ten. there is no soft or strong dynamics but everything on the violins, violas and cellos are notated pppp and even emphasized by an inscription:imperceptible attack.

Only the changes at any of the boundaries, the highest and lowest notes for each part will be considered for sketching the resulting clusters.

The notation below reflects the vertical extends and changes in each of the parts in a cluster notation.

Figure: Bars: 44-47. Cluster notation shows that there is only a few significant shiftings in ranges.

31#31

The cluster notation shows that all voice motions are neutralizing each other. So the projected sound-cloud is a static object on its outlines.
