FM synthesis is a sound-design–driven electronic style built around frequency modulation techniques, where one oscillator (the modulator) alters the frequency of another (the carrier) to create complex, evolving spectra. The result is famously bright, glassy, and metallic timbres—bell tones, electric pianos, plucks, basses, and inharmonic percussion—that are difficult to achieve with subtractive or wavetable methods. As a musical aesthetic, FM synthesis coalesced around the Yamaha DX series (especially the DX7, 1983) and later 4‑operator units like the TX81Z, spreading through 1980s pop, city pop, new age, jazz fusion, and game music. Its signature presets (e.g., "E. PIANO 1", "Lately Bass") defined the sonic palette of mid‑80s to early‑90s recordings, while FM chips in consoles and arcades shaped the sound of an entire era of video games. Today, FM remains a distinct compositional palette: crystalline highs, punchy transient detail, and harmonically rich but precise tones that can feel both futuristic and nostalgic.

Experimental music is an umbrella term for practices that prioritize exploration, process, and discovery over adherence to established genre norms. It embraces new sound sources, nonstandard tuning systems, indeterminacy and chance operations, graphic and open-form scores, extended techniques, and technology-led sound design (tape, electronics, computers, and live processing). Rather than a single style, it is a methodology and ethos: testing hypotheses about sound, structure, and performance, often blurring boundaries between composition, improvisation, sound art, and performance art. Listeners can expect unfamiliar timbres, unusual forms, and an emphasis on how music is made as much as the resulting sound.

Avant-garde music is an umbrella term for boundary-pushing practices that challenge prevailing norms of harmony, rhythm, timbre, form, and performance. It privileges experimentation, conceptual rigor, and a willingness to reframe what counts as music at all. Historically tied to early 20th‑century artistic modernism, avant-garde music introduced atonality, the emancipation of noise, and new forms of notation and process. It embraces indeterminacy, extended techniques, electronics, spatialization, and multimedia performance, treating sound as material to be sculpted, questioned, and reinvented.

Electronic is a broad umbrella genre defined by the primary use of electronically generated or electronically processed sound. It encompasses music made with synthesizers, drum machines, samplers, computers, and studio/tape techniques, as well as electroacoustic manipulation of recorded or synthetic sources. The genre ranges from academic and experimental traditions to popular and dance-oriented forms. While its sonic palette is rooted in electricity and circuitry, its aesthetics span minimal and textural explorations, structured song forms, and beat-driven club permutations. Electronic emphasizes sound design, timbre, and studio-as-instrument practices as much as melody and harmony.
