40 years of sound — today, targeted stimulation for the nervous system. Composed sound and light for focus, calm and sleep.
Four channels, one goal: reliably trigger the desired state instead of random relaxation. They interlock — composed by hand, not generated.
Hand-composed soundscapes and brainwave entrainment. 40 years of audio-engineering craft, aimed precisely at brainwaves.
Rhythmic light pulses (AVS), synchronised to the sound. They reach the nervous system through the visual system.
Verbal guidance directs attention and gives the state meaning. It frames and deepens the experience.
Guided breathing as the pacemaker. Anchors the state in the body and makes it repeatable.
Focus, meditation or relax — every album is composed to reliably trigger exactly one state. Almost 2M streams, streamable and available to buy.

All five elements in one continuous sound journey — from earth to ether. 15 tracks, composed by Ivo Vossen.
Listen & buy →Experienced meditation and coaching professionals lay their guided sessions over Ivo's compositions. Joint albums that bring his method into practice.
From a live session to a tailored sound licence — for partners, organisers and brands.
Light & Sound Baths and Neuro-Tuning, live in the room or online. Corporate and team workshops are delivered by Ivo as BE LIGHT ↗.
Tailored compositions for spaces and brands, plus catalogue licensing (sync).
Talks on sound, light and the nervous system — for conferences, companies and media.

Ivo Vossen is a musician, composer and audio engineer with 40 years of experience in live, events and audio production. His own compositions reach millions of streams.
From this craft grew Resonance Space and BE LIGHT — the mental-fitness app Ivo co-founded, which puts the method into the hands of thousands.
Discover BE LIGHT ↗Sound, light, voice and breath synchronise the brainwaves toward a target frequency — brainwave entrainment. Together with BE LIGHT and HAW Hamburg, the effect on the nervous system is being studied.
Alpha (8–12 Hz) is the central frequency for relaxation and presence. Theta & Delta for deep meditation and sleep, Beta for focus.
Resonance Space is Ivo Vossen's neuro-audio project: hand-composed sound with brainwave entrainment, composed to reliably trigger a specific state — focus, calm or sleep.
Ivo Vossen is a musician, composer and audio engineer with 40 years of experience in live, events and audio production. With Resonance Space he composes sound and light specifically for the nervous system (brainwave entrainment) and is the founder of the mental-fitness app BE LIGHT. His compositions reach almost 2 million plays across all platforms.
Brainwave entrainment describes how rhythmic stimuli — sound, light pulses (AVS), breath and guided voice — lead the brainwaves toward a target frequency. The hand-composed interplay of these four channels is what Ivo calls Neuro-Tuning.
Through brainwave entrainment: sound, light (AVS), voice and breath guide the brainwaves toward a target frequency — for example Alpha (8–12 Hz) for relaxation, Delta for deep sleep, Beta for focus.
With the four frequency bands: Beta (13–30 Hz) for focus, Alpha (8–12 Hz) for relaxation, Theta (4–8 Hz) for deep meditation and Delta (0.5–4 Hz) for deep sleep.
Each album is composed by hand and aimed at a specific brainwave target frequency — not random background music, but designed to reliably trigger a state. Combined with light pulses (AVS), breath and guided voice.
The method is based on the established principle of brainwave entrainment. Together with BE LIGHT Now GmbH and HAW Hamburg, exploratory EEG measurements are underway. This is not a medical claim and not a promise of healing.
For anyone who wants to reach a specific state on purpose: focus while working and studying, calm and sleep in the evening, depth in meditation. Used by individuals, coaches as well as teams and companies (light-and-sound workshops).
Resonance Space is Ivo Vossen's sound and music project — composed sounds to stream and buy. BE LIGHT is the mental-fitness app he co-founded, which brings the same method as guided sessions into the hands of thousands.
