Lowercase is a minimalist strain of experimental ambient music that privileges extremely quiet, often barely-perceptible sound. Instead of melody and rhythm, it focuses on micro-sonic details—hiss, hums, room tone, paper rustle, HVAC drones, cable buzz, and distant environmental traces—presented at very low volumes. Coined by artist Steve Roden in the early 2000s, the term denotes both a sonic aesthetic and a listening practice: attentive, headphone-based, and patient. Releases frequently use long durations, wide dynamic range, and near-silence to pull listeners toward the threshold of audibility. Labels such as 12k, LINE, and Trente Oiseaux, along with galleries and sound-art contexts, helped situate lowercase at the intersection of ambient, electroacoustic composition, and conceptual sound art.

Microsound is an experimental electronic music aesthetic that focuses on sound at extremely small time scales, often in the range of milliseconds. Rather than developing melodies and rhythms in the conventional sense, it foregrounds the grain, texture, and morphology of audio—clicks, cuts, sine blips, static, and near-silent filigree—arranged with surgical precision. Heavily shaped by digital signal processing and granular/spectral techniques, microsound treats errors, residual noise, and computational artifacts as musical material. The results are sparse, highly dynamic soundfields that emphasize detail, negative space, and the sensation of listening under a microscope. The style sits at the intersection of glitch, ambient, electroacoustic composition, and minimalism, and it is frequently associated with labels and artists who advanced “post-digital” aesthetics in the late 1990s and early 2000s.

Field recording is the practice and genre of capturing sounds in situ—outside the studio—using portable recording equipment. It centers on documenting environments, human activities, wildlife, weather, machinery, rituals, and music as they actually occur, often with minimal intervention. As a listening genre, field recording foregrounds place and presence. Releases may present unprocessed, extended takes (e.g., a shoreline at dawn), or carefully edited sequences that map a soundwalk, a village festival, or a factory floor. The results range from documentary-style fidelity to abstract, immersive soundscapes that emphasize texture, spatiality, and the ecology of sound.
