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.

Baroque is a period and style of Western art music spanning roughly 1600–1750. It is characterized by the birth of functional tonality, the widespread use of basso continuo (figured bass), and a love of contrast—between soloist and ensemble, loud and soft, and different timbres. Hallmark genres and forms of the era include opera, cantata, oratorio, concerto (especially the concerto grosso), dance suite, sonata, and fugue. Textures range from expressive monody to intricate counterpoint, and melodies are richly ornamented with trills, mordents, and appoggiaturas. Baroque music flourished in churches, courts, and theaters across Europe, with regional styles (Italian, French, German, English) shaping distinctive approaches to rhythm, dance, harmony, and ornamentation.

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.

Mass is a large-scale vocal genre that sets the Ordinary of the Roman Catholic liturgy—Kyrie, Gloria, Credo, Sanctus (and Benedictus), and Agnus Dei—most often in Latin. It began as monophonic chant but developed into sophisticated polyphony and later into concert works for choir, soloists, and instruments or full orchestra. Across history, composers have used techniques such as cantus firmus, imitation, paraphrase, and parody to unify movements. The genre spans from austere a cappella writing to monumental symphonic-choral statements, and today is performed both liturgically and in the concert hall. Common subtypes include Missa brevis (short Mass, often omitting the Credo or compact in scale) and Missa solemnis (festal, expansive forces and duration).

Medieval music refers to the diverse sacred and secular musical practices of Europe between the fall of the Western Roman Empire and the dawn of the Renaissance. It spans more than eight centuries, from early monophonic chant to the first notated polyphony. Core features include the use of church modes rather than major/minor, extensive reliance on vocal music (Latin sacred chant as well as vernacular song), and the progressive development from unmeasured chant to rhythmic modal notation and, later, mensural notation. Texture evolves from monophony (plainchant, troubadour songs) to organum, conductus, and the motet, culminating in complex isorhythmic works by the late 13th–14th centuries. Secular traditions—troubadours and trouvères in France, Minnesänger in German lands, and the Iberian Cantigas—coexisted with and influenced sacred practice. Instruments such as the vielle, harp, psaltery, recorder, shawm, hurdy-gurdy, and portative organ often doubled or accompanied voices, though much music remained purely vocal.

Opera is a large-scale theatrical genre that combines music, drama, and visual spectacle, in which the story is primarily conveyed through singing accompanied by an orchestra. It unites solo voices, ensembles, and chorus with staging, costumes, and often dance to create a total artwork. Emerging in late Renaissance Italy and flourishing in the Baroque era, opera developed signature forms such as recitative (speech-like singing that advances the plot) and aria (lyrical numbers that explore character and emotion). Over the centuries it evolved diverse national styles—Italian bel canto, French grand opéra, German music drama—while continually experimenting with orchestration, harmony, narrative structure, and stagecraft.

An oratorio is a large‑scale, multi‑movement work for voices and orchestra, typically on a sacred narrative subject, performed without staging, costumes, or scenery. It combines solo recitatives and arias with powerful choruses and instrumental movements, using a dramatic arc similar to opera but presented as a concert work. Languages and styles vary by era and region (Italian and Latin in early Roman oratorios, German for Lutheran works such as Bach’s, and English for Handel’s). While most are sacred, secular oratorios also exist. Across the Baroque, Classical, Romantic, and modern eras, the oratorio evolved from intimate devotional storytelling to monumental public concert pieces, often intended for festivals and large choirs.

Renaissance music (c. 1400–1600) marks the shift from medieval sonorities to a clearer, triad-based polyphony in which multiple independent voices are treated with near-equal importance. It favors modal counterpoint, pervasive imitation, smooth voice-leading, and carefully prepared cadences. Text intelligibility and expressive text-setting become central concerns, especially in sacred motets and masses and in secular forms like the Italian madrigal and the French chanson. While much of the repertory is a cappella, instrumental consorts (viol, recorder, sackbut, cornett, organ) play a growing role. A steady tactus underpins rhythms, and tuning systems such as meantone temperament shape its characteristic color. Music printing (from 1501) accelerates stylistic diffusion across Europe.

Chamber music is a tradition of composed music for small ensembles—typically one player per part—intended for intimate spaces such as courts, salons, and private rooms rather than large public halls. Its aesthetic emphasizes clarity of texture, conversational interplay among parts, and balance without a conductor. Hallmark formations include the string quartet, piano trio, wind quintet, string quintet, and various mixed ensembles. Multi‑movement cycles (often in sonata form) and finely wrought counterpoint are common, ranging from Baroque trio sonatas to Classical string quartets and modern works with expanded timbres and techniques. Because of its scale and transparency, chamber music has long been a proving ground for compositional craft and ensemble musicianship, shaping the core of Western art music from the Baroque through the present.

Choral refers to music written for and performed by a choir—an ensemble of voices organized into sections such as soprano, alto, tenor, and bass (SATB), or same-voice groupings (SSA, TTBB). It encompasses both sacred and secular repertoire and may be sung a cappella or with accompaniment by organ, piano, or full orchestra. Stylistically, choral music ranges from chant-like monophony to intricate polyphony and rich homophonic textures. Texts are drawn from liturgy, scripture, poetry, and vernacular sources, and are set in many languages. Performance contexts include church services, concert halls, and community events, making choral one of the most socially embedded and widely practiced forms of ensemble music. Across history, choral music has served as a laboratory for vocal counterpoint, word painting, and text-driven form, while functioning as a cultural bridge among religious rites, national traditions, and contemporary concert practice.

Modern classical is a contemporary strand of instrumental music that applies classical composition techniques to intimate, cinematic settings. It typically foregrounds piano and strings, is sparsely orchestrated, and embraces ambience, repetition, and timbral detail. Rather than the academic modernism of the early 20th century, modern classical as used today refers to accessible, mood-driven works that sit between classical, ambient, and film music. Felt pianos, close‑miked string quartets, tape hiss, drones, soft electronics, and minimal harmonic movement are common, producing a contemplative, emotionally direct sound that translates well to headphones, streaming playlists, and screen media.
