Improving the practice and performance of contemporary music
Section 4: mp
The alternating use of pitches and successions of intervals to create panels is continued in the rest of part I of Mari. Previously applied filters also return to further enhance the musical material. Where diatonic clusters are built by doubling two consecutive notes in a previous passage, now an inverted filter – to break the clusters down – is applied to shape the musical material into a new phrase. By filtering one of the two notes out of a cluster, a new series of intervals is created, which functions as a panel in retrograde this time.
After the cluster passage, the end of the first new melody is obtained by prolonging the tail of this phrase using a filter. The last cell that is created out of the filtering of the clusters contains two components that prolong the melody. The filter applied here always uses the core of those two components to bring the phrase to a close.
