Czech sound artist Vojtech Vesely, known as De Moi, introduces Drifting Intervals I, the opening piece from a project built around an ambient technique of the same name. Rooted in tape delay systems and extended decay, the track demonstrates a carefully structured process of harmonic blending, resulting in a sound that evolves gradually and continuously.
Drifting Intervals I unfolds slowly, with tonal fragments that layer and merge into a fluid, cloud-like atmosphere. The piece maintains a steady sense of motion without relying on traditional rhythm or melody, instead drawing focus to the slow transformation of sound over time. The use of deep reverberation and extended decay allows individual intervals to dissolve into a broader harmonic field, forming a cohesive ambient texture that shifts subtly but constantly.
The track showcases Vesely’s Drifting Intervals method—an approach inspired by the tape loop experiments of William Basinski, the delay systems of Terry Riley and Robert Fripp, and Pauline Oliveros’ Deep Listening. Using layered musical intervals fed through a tape delay system, Vesely introduces gradual harmonic changes that build into a seamless ambient whole.
Vesely’s background spans sound installations, composition for audiobooks, and workshop facilitation in experimental music and sound design. His work often blends theoretical and practical approaches to sonic exploration, with Drifting Intervals I reflecting both his technical knowledge and compositional restraint.
The track is part of a full album now available, which expands on the Drifting Intervals method across multiple compositions. With Drifting Intervals I, De Moi presents a meditative and immersive listening experience grounded in a precise and imaginative approach to ambient music.
