Content:
In 'Transformationen' several layers of time and media are superimposed:
- the music playback is based on an old recording of a piece (ergo-sum'pf'maschinerie) from 1989 (recorded at the time by the violinist Susanne Schulz and myself on the synthesiser/sampler), which was edited and reassembled for the 'Transformationen' series. The basis of the piece at that time was, among other things, field recordings that I had made in the 1980s with a Sony Professional in Spain at a certain waterhole and then edited in a Casio sampler (with 1MB storage capacity!). An endless number of frogs had gathered at this watering hole every evening for their daily concert. Today there is neither a watering hole nor frogs anymore - and the Casio-FZ1 sampler is only used as a term in stories about the beginnings of sampler technology.
- The voiceover is a recording of a voice from March 2022 reading the text of the above poem.
- The singers add another dimension of time and space.
In the 'real time' of the performance, different layers of time and space, long past, quasi 'archaeological' sounds from the feed, an acousmatic voice and the 'now' sound of the violin in concert are thus mixed together. In a way, this approach echoes the title and content of the poem 'Diepe tijd' (Deep Time) by Flemish writer Dominique de Groen. The term was introduced by the writer John McPhee in 1980/81 to describe a time dimension of millions or even billions of years that does justice to the slow evolutionary processes on earth. Such a view of time and evolution exceeds the capacity of human consciousness.

Technical information:
The playback consists of two audio files (44.1 khz, 16bit):1.) the spoken text - beginning with a long pause
2.) the 'music' (stereo)
Both files must be started at exactly the same time. This requires appropriate playback software and a multi-channel mixing console

Amplifier system
For optimum projection in the room, different amplifier boxes are desirable in order to be able to separate speech, music feed and live vocals from each other.
- The music feed should form an acoustic 'frame' and encompass the entire stage area via large, powerful stereo speakers.
- If possible, the voice band should be projected via one (or two) extra speaker(s) placed on the stage - and thus mark a 'separate' space. The lyrics must be clearly understandable, both from the audience and from the musicians themselves (as it structures their various performances).
- If possible, the voices should be amplified via local stereo speakers. Their sound creates its own acoustic space in the playback environment. The voices must stand out acoustically from the music feed, thus acoustically representing a layer 'in front' of the feed. By 'in front' we mean more 'directness', but also a little more volume (the feed itself contains significant reverb components, so it already seems 'further away' due to the way it is mixed).
The music feed is available in a dynamically mixed version. Depending on the room, it may be necessary to 'drive' the feeds and the live violin.

Microphoning:
Depending on the room, the singers may each need a stand microphone and a headset to make their vocal articulations audible and integrate them into the overall acoustic picture.

Live singing:
Following the logic of the poem, the piece 'takes place' in the time after humans and thus belongs, if you like, to the genre of 'science fiction'. Accordingly, there is hardly any 'human' expression in 'Transformations II' in the form of music as we are used to: Lines, progressions, phrases, bows etc. Instead, we hear cell-like, sometimes repetitive and slightly varying punctual figures that run parallel to the tape and harmonise in register with the tape. In their expression, these punctual sounds are sometimes reminiscent of the delicate lamentation of non-human beings. The sounds to be found are thus intended to appear 'creaturely' in their delicacy and indeterminacy. Only at the very end is there a 'traditional' musical passage reminiscent of (human) times long past.

Timing/coordination with the tape:
The dense musical interlude determines the piece. It provides sound spaces (registers, 'keys') that also influence the live singing. The singers must therefore be able to follow the music well in order to be able to 'sing along' accordingly.
Attention! - the course of the feed is not always notated exactly! Also, the tempo is sometimes more fluctuating than is notated (e.g. that of the violin part of the long opening section);the spoken words are decisive for the overall coordination; they enable the time orientation and must be followed in any case! If necessary, certain note passages must be adapted/interrupted/faded out etc. if the feed and live music move apart. The material notated in the score is therefore to be understoodas a suggestion. It may be possible to deviate from this if the basic intention of the piece is retained.

Dynamics of the live voices:
The volume levels notated in the score must be readjusted in each room. However, the ratios should be maintained. It may be necessary to play certain passages as a whole one or more dynamic levels louder or softer. Depending on the room, it may be necessary to 'drive' the voices and feeds from the mixing console.
