Synthesizer (as a genre tag) refers to music that foregrounds the electronic synthesizer as the primary sound source, celebrating timbre design, sequenced patterns, and the tactile possibilities of analog and digital electronics. It spans from early modular explorations and Moog/Buchla demonstrations to Berlin School sequences, space-age textures, and virtuosic keyboard reinterpretations of classical and popular repertoire. Emphasis is placed on sound design (oscillators, filters, envelopes, modulation), repeating motifs, and textural development, often with minimal lyrics or none at all. While the instrument is used across countless styles, the "synthesizer" category highlights works where the identity, techniques, and sonorities of the synth itself are the core aesthetic focus.

Jazz is an improvisation-centered music tradition that emerged from African American communities in the early 20th century. It blends blues feeling, ragtime syncopation, European harmonic practice, and brass band instrumentation into a flexible, conversational art. Defining features include swing rhythm (a triplet-based pulse), call-and-response phrasing, blue notes, and extended harmonies built on 7ths, 9ths, 11ths, and 13ths. Jazz is as much a way of making music—spontaneous interaction, variation, and personal sound—as it is a set of forms and tunes. Across its history, jazz has continually hybridized, from New Orleans ensembles and big-band swing to bebop, cool and hard bop, modal and free jazz, fusion, and contemporary cross-genre experiments. Its influence permeates global popular and art music.
