Program notes

The basic sounds used in this piece are recordings of vibrating „tongues“.
In musical acoustics the German word „Zunge“ (tongue) is a basic term for single and double reeds in woodwinds, like oboe, clarinet or saxophone, as well as reeds or vibrating plates in the accordion, harmonica, jews harp or some organ pipes. Even the lips of a brass player or the human vocal cords can be regarded as „vibrating tongues“.
The resonance frequency of these reeds and lips determines, sometimes in connection with a coupled cavity or a tube, the pitch that we will hear.The vocal cords, the vocal tract and the tongue are the basis for the production of different vowels, consonants and varying pitches – physical fundament of speech and singing and thus of music.
According to the generally recognized theory of evolution the language and the speech production tools were developed to get the human race a survival advantage.

Is music a result of natural selection?
Is there a connection between art and evolution?

The linguist Stephen Pinker suggests that music is „auditory cheesecake

Realization notes

The signal processing, the sound transformation and structuring processes in this piece are written in SuperCollider3 running on MacOSX. Later on the multichannel textures, processes and single sounds were arranged with Nuendo.
Almost all structuring algorithms are derived from L-systems, which can be described by rewriting patterns in SuperCollider. L-systems and transformational grammars are well known in linguistics as well as in bio-mathematics and even in musicology as analysis tools to describe the basic design or „construction plan“ of complex systems, like human language grammars, plants or classical symphonies.
