glslViewer's `u_mouse` is in pixels, not 0..1 — normalize by `u_resolution` before use

Goa trance parties have a definitive visual identity using fluorescent paint, psychedelic tapestries, and spiritual iconography

Goa trance traditionally uses vocal samples referencing psychedelia, cosmic science, and spirituality rather than sung lyrics

Goa trance uses one long steadily-building arc, not a drop, to induce collective trance

Goa trance's signature squelchy sound is a sawtooth wave through a resonant band-pass or high-pass filter

Golden-age hip-hop records (1986–1993) assembled dozens of samples per track in ways that are legally impossible to clear today

Goldie elevated DnB from underground rave music to a respected art form through artistic ambition

GPU shaders run massively in parallel — individual invocations cannot communicate with or observe each other within a pass

GPUs work exclusively with triangles, lines, and points — all geometry must be decomposed into triangles before drawing

Granular synthesis builds textures from clouds of short enveloped sound grains

Grime and dubstep shared tempo and geography but diverged on MC culture, beat density, and synth aesthetics

Grime applied the same self-reliant hustle logic as the informal economy to cultural production, achieving distribution without industry gatekeepers

Grime artists distributed music through sell-or-return white-label vinyl at independent record shops before any digital distribution infrastructure existed

Grime emerged from jungle/drum-and-bass by slowing the tempo to 140 BPM and creating space for MC delivery over darker bass-driven instrumentals

Grime producers sample chiptune and video game sounds because these textures were already embedded in East London everyday life

Grime's 8-bar loop format switches beats every eight bars, giving MCs a different rhythmic foundation each cycle

Grime's canonical 140 BPM tempo originated partly because FL Studio's default tempo is 140 BPM

Grime's drum texture layers a slow half-time skeleton under fast 2-step hi-hats at 140 BPM, generating tension between perceived speeds

Grime's signature proto-sound featured staccato strings, eski bleeps, and square wave bass — hallmarks shared with video game music

Grime's stripped-back, distorted, bass-heavy sound emerged directly from the emotional reality of gang violence and police suppression of the garage scene

Groove (the pocket) lives in the micro-timing variations between mechanically perfect beats

Guitar feedback is a self-sustaining tone that lets rock musicians generate drones without a bow or wind

Hand-coding world knowledge in formal rules failed, motivating machine learning from data

Happy hardcore is defined by sped-up breakbeats running alongside a four-on-the-floor kick, distinguishing it from gabber

Hard dance is an umbrella term for fast 4/4 genres that are less harsh and often slower than hardcore

Hard NRG is a darker, faster variant of UK hard house that swaps uplifting energy for ominous aggression

Hardcore techno evolved from industrial music and EBM via Belgian new beat and acid house

Hardcore techno is defined by a 160–200 BPM tempo and a distorted, saturated kick

Hardcore techno's subgenres are differentiated mainly by tempo range, mood, and regional origin

Hardstyle emerged in the late 1990s from the Netherlands, Belgium and Italy, out of hard trance and hardcore

Hardstyle is defined by 140–150 BPM tempo, a distorted and pitched kick drum, and euphoric supersaw leads

Hardstyle's tempo rose from about 140 BPM in the early 2000s to roughly 150-160 BPM in modern material

Hardware cost and internet access are the first barrier to live coding, unevenly by region and income

Hardware hacking reframes consumer electronics as performable instruments, with the body part of the circuit

Harmonics are the standing waves at integer multiples of a fundamental frequency

Harsh noise originated in 1980s Japan through the Japanoise scene, growing from the Kansai no wave movement

Harsh noise rejects melody, rhythm, and harmony in favor of distortion, feedback, and dense static

Headphones expose translation and low-level faults that room-bound speakers hide

Heartless Crew moved the MC front-and-centre in UK garage, a shift the established scene resisted but which became the structural basis of Grime

High-pass filtering non-bass tracks removes low-frequency energy that only muddies the mix

Hip house fused four-on-the-floor house beats with hip-hop flows in the late 1980s

Hip-hop producers mine two-bar drum breaks from funk and soul records as foundational rhythmic loops

Historic regional mixing styles (New York, LA, London, Nashville) reflect different philosophies toward compression, effects, and arrangement

Home tape dubbing is an early form of active, compositional listening

House (Chicago), techno (Detroit), and garage (New York) emerged in parallel as three related early-1980s US dance scenes

House music found early acceptance in Northern England because Northern Soul fans already had a culture of uptempo four-to-the-floor Black American dance music

House music synthesised Black American post-disco and European EBM/electro in a transatlantic dialogue

House music was a low-budget recreation of disco using drum machines and synthesisers instead of orchestras and live bands

House music was invented in Chicago by Black DJs and musicians, not in London or Europe

House's characteristic sound emerged when Chicago DJs added drum machines to compensate for scarce records

HSB describes color as hue, saturation, and brightness for intuitive, intentional variation

Human hearing peaks in sensitivity at 3–4 kHz due to ear canal resonance

Human trichromacy means any color sensation can be described by three numbers

Hydra buffer objects (`s0`, `o0`) are not chainable sources — they must be wrapped in `src(...)`

Hydra can use webcams, screen capture, video files, and images as source buffers alongside generated visuals

Hydra feedback with `src(o0)` blows out to white if the fed-back signal is added or scaled ≥ 1

Hydra FFT bins stay at 0 until a Strudel pattern is tagged `.analyze('hydra')`

Hydra functions fall into five categories: source, geometry, color, blending, and modulation

Hydra has four independent output buffers (o0–o3) that render separately and can be cross-mixed

Hydra models analog video synthesis: each function is a box that generates or transforms a signal
