Uderochromatism
Composing from the belly and turning inner perception into creative material.
Definition
The word Uderochromatism is a neologism. It combines the reconstructed Proto-Indo-European root udero-, referring to the belly, abdomen or womb and notably giving rise to the Latin uterus, with chromatism, a term used in colour and music.
Uderochromatism is an experimental artistic practice based on the exploration and translation of inner perceptions, particularly what is felt in the belly before words, representation and sometimes even the conscious identification of an emotion.
In its original definition, it designates vibratory tonalities attributed to visceral emotions and their artistic transcription into hexadecimal colour values.
It invites us to compose from the belly and describe the inner world through a language of chromatic frequencies, creating sensitive ecosystems rather than finished objects.
Its raw material is not an object to represent but a sensitive state in transformation: tension, rhythm, breath, intensity, density, displacement, vibration or diffuse sensation.
These phenomena may be translated, displaced or recomposed through colour, sound, gesture, frequency, space, rhythm, trace and time. Translation establishes no fixed correspondence between sensation and form: it opens a field of variation in which inner experience becomes creative material.
Uderochromatism thus develops an invisual practice. It does not begin with what is seen in order to represent it, but with what is felt before finding an image or form.
It regards the body — and especially the belly — as an active territory of perception, creation and experimentation. Inner musicality is the possibility of organising the intensities, rhythms, movements and temporalities of sensitive experience as musical material.
Uderochromatism neither illustrates emotion nor mechanically decodes the body. It creates the conditions in which inner perception can transform, move and bring forth a singular form.
Developed within uNRu, it is gradually forming an ecosystem of its own concepts, languages, instruments, protocols and artistic forms.
A philosophical source
Uderochromatism presents itself as a re-emergence of the sensitive: a field of organic inscription seeking to reactivate a primary sensoriality. Irreducible to the abstract logics of cognitive capitalism and the capture mechanisms of patriarchal technocentrism, it offers a critical response to the modern separation of reason and body, sign and sensation, human subject and lived world.
By bringing visceral emotions into colour and music, Uderochromatism enables a return to embodied, vibrant perception. It thus forms a counter-proposal to contemporary processes that disembody and deaden the sensitive, reactivating the living memory of preverbal perceptions that modern rationality tends to marginalise.
The four pillars
The structure of Uderochromatism
01
The Music of Inner Experience
The music of Uderochromatism emerges from the emotional intensity felt in the belly. Rather than arranging notes according to an external structure, it seeks to make an inner modulation audible: a sequence of tensions, silences, pulses and returns.
This music does not imitate the body’s processes. It offers a sensory translation of them. A sensation may take the form of rhythm, duration, density or sonic variation. A restrained emotion may emerge as a slow pulse, a rupture, a saturation or a suspension.
Silence is essential to this musical language. It is not the absence of composition, but a space for listening and attention, allowing inner manifestations to become perceptible.
The work takes shape through the relationship between the instrument, the participant’s inner state and their actions. This sensory and sensorimotor co-creation makes every experience a unique composition.
02
The Belly as a Resonating Chamber
Uderochromatism locates emotion in the belly, not to confine it to a specific organ, but to acknowledge an immediate bodily experience.
The belly may tighten, contract, rise, tremble or release before we are even able to identify what is moving through us. It forms a preverbal territory, where emotions emerge before language gives them shape.
Choosing the belly as a site of creation shifts attention. The body is no longer merely the receiver of the work: it becomes its source, medium and resonating chamber.
The belly becomes a sensory matrix holding conflicting movements, diffuse tensions, impulses, withdrawals and intensities that have not yet settled into a stable form.
Visceral emotion remains unstable, shifting and inseparable from the moment in which it is felt.
03
Emotion as an Embodied Alter Ego
In Uderochromatism, emotion is more than a psychological state or passing reaction. It is imagined as an inner presence: a sensitive, autonomous and mutable creature inhabiting the belly.
This creature has no fixed form. It may gather, fragment, contract, expand or disappear.
Giving it an imagined body makes an otherwise diffuse experience perceptible. Emotion becomes an embodied alter ego.
As its vibrations symbolically pass through the abdominal wall, they are transformed through a process of sculpturation into chromatic pulses and geometric or organic forms.
This is not an anatomical representation. It creates an emotional morphology.
Emotion may become rounded, angular, scattered, compact, fluid or discontinuous, acquiring presence without losing mobility.
04
The Sonification of Colour
In Uderochromatism, colour is neither decorative nor symbolic. It participates directly in translating visceral experience.
This approach rejects fixed associations automatically linking red with anger, blue with sadness or yellow with joy.
Colour is not selected as a rational code: it calls out.
It may arise as an inner necessity, saturation, breath or signal.
Sonified colour is not based on a mechanical equivalence between light and sound frequencies. Their relationship is conceived as sensory rather than literal physical translation.
Colour may become rhythm, duration, tension or pulse, while music may extend into visual and visceral dimensions.
In an uderal composition, colour remains in motion. It breathes, shifts and disappears with the emotion that brought it into being.
The four pillars form a single process: the belly receives emotion, emotion acquires presence, its vibrations become forms and chromatic pulses, and colour unfolds through sound, rhythm and silence.
