Vocal gliss

The vocal gliss fragments are short signals appearing at different times during the work. Initial and final points of the glissandi are found from the same set of tam-tam analyses used in sound installation fragments. These partial trackings1 go through a chain of filterings.

These procedures only select and approximate 5 tones, one for each singer, there are no additional distortions or transpositions. Initial and final chords are found from 2 different extracts from these tam-tam partial trackings to form a basis for transitions.

The result will have more characteristics of glissando textures than of the initial tam-tam spectrums.

The raw materials contained intermediate tones for a useful MIDI playback. Not all of this information was necessary for a live performance.

The final score was simplified to only show glissando dirations. The very high vocal register of Stine Motland gave a character to this fragment.
