Symphony No. 5 in C minor, op. 67

Non-music is an umbrella category for recorded audio whose primary purpose is not musical performance. It encompasses spoken word, speeches, interviews, poetry readings, comedy, audio documentaries, instructional recordings, field recordings, sound effects, and other forms of organized sound meant to inform, narrate, document, or entertain without relying on melody or conventional song structure. Rather than emphasizing harmony, rhythm, and instrumentation, non-music foregrounds voice, text, ambient sound, narrative flow, informational content, and sonic texture. Its aesthetics range from raw, unedited actuality to highly produced studio works, and its scope spans archival preservation, education, performance art, and mass entertainment.

Speech is a non-music recording category focused on intelligible spoken language rather than melody, harmony, or meter. It encompasses political addresses, public announcements, news bulletins, commemorations, and other forms of formal oratory captured as audio. Unlike spoken word poetry or stand-up comedy, the emphasis in speech recordings is on clear rhetoric, message delivery, and documentary value. The production prioritizes intelligibility, natural prosody, and sonic transparency, often avoiding musical accompaniment so that content remains archival, reference-grade, and contextually faithful. From wax cylinders and shellac discs to radio tape, cassettes, digital broadcast, and streaming archives, speech has been a core use-case of audio media, preserving moments of civic life, cultural change, and history in their original voices.

Classical music is the notated art-music tradition of Europe and its global descendants, characterized by durable forms, carefully codified harmony and counterpoint, and a literate score-based practice. The term “classical” can refer broadly to the entire Western art-music lineage from the Medieval era to today, not just the Classical period (c. 1750s–1820s). It privileges long-form structures (such as symphonies, sonatas, concertos, masses, and operas), functional or modal harmony, thematic development, and timbral nuance across ensembles ranging from solo instruments to full orchestras and choirs. Across centuries, the style evolved from chant and modal polyphony to tonal harmony, and later to post-tonal idioms, while maintaining a shared emphasis on written notation, performance practice, and craft.
