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.

A concerto is a large-scale composition that sets one or more solo instruments in dynamic dialogue with an orchestra. Its core idea is contrast—between soloist and tutti—and the dramatic negotiation of power, color, and thematic responsibility. While Baroque concertos often relied on ritornello form, the Classical era standardized a three-movement plan (fast–slow–fast) with sonata principles in the opening movement. The Romantic period emphasized virtuosity and expressive foregrounding of the soloist, and the 20th–21st centuries broadened the palette with new instruments, harmonies, and formats. Across eras, the concerto remains a showcase for instrumental character, technical brilliance, and the art of orchestral conversation.

Fado is an urban Portuguese song tradition centered on the feeling of saudade—an untranslatable mix of longing, nostalgia, and bittersweet melancholy. It emerged in 19th‑century Lisbon’s working-class neighborhoods and port districts and later developed a distinct academic strain in Coimbra. Typically performed by a solo singer (fadista) with accompaniment from the 12‑string guitarra portuguesa (Portuguese guitar) and a 6‑string viola (classical/steel‑string guitar), fado favors minor keys, expressive rubato, and ornate melodic embellishment. Its poetry (often in quatrains) contemplates love, fate, the sea, and everyday hardship. Two principal styles dominate: Fado de Lisboa, intimate and dramatic, and Fado de Coimbra, associated with student serenades and a more classical, restrained delivery. Recognized by UNESCO in 2011 as Intangible Cultural Heritage, fado remains a living tradition continually renewed by contemporary interpreters.

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.

Romantic classical is the 19th‑century phase of Western art music that prioritizes individual expression, expanded harmony, poetic narrative, and coloristic orchestration. Compared with the balance and restraint of the Classical period, Romantic music embraces chromaticism, adventurous modulation, extreme dynamics, and richer timbres. It elevates subjectivity and imagination, often through programmatic works that depict stories, landscapes, or emotions, and through intimate forms such as the Lied and character piece. The orchestra grows dramatically (trombones, tuba, expanded winds, harp, larger percussion), the piano becomes a virtuoso vehicle, and new concepts like thematic transformation and leitmotif link music to literary and dramatic ideas.

A sonata is a multi-movement work for one or a few instruments that developed as a principal vehicle of instrumental expression in European art music. In the Baroque era it referred broadly to “music to be sounded” (as opposed to “cantata,” music to be sung) and commonly appeared as the trio sonata (two treble instruments plus basso continuo) in church (sonata da chiesa) or chamber (sonata da camera) contexts. In the Classical era the term narrowed to denote a cyclical, architecturally unified piece for solo keyboard or for a solo melody instrument with keyboard, typically in three or four movements with the first movement in sonata form (exposition–development–recapitulation). Across the 18th–20th centuries, composers used the sonata as a laboratory for harmonic drama, motivic development, and contrasting characters—ranging from the poised clarity of Haydn and Mozart to the structural expansiveness and psychological depth of Beethoven and Romantic successors.

A symphony is a large-scale composition for orchestra, typically cast in multiple movements that contrast in tempo, key, and character. In the Classical era, the most common layout was four movements: a fast opening movement (often in sonata form), a slow movement, a dance-like movement (minuet or later scherzo), and a fast finale. Over time, the symphony evolved from compact works of the mid-18th century into expansive, architecturally ambitious statements in the 19th and 20th centuries. Composers increasingly treated the symphony as a vehicle for thematic development, cyclical unity, and dramatic narrative—sometimes programmatic, sometimes abstract—using the full coloristic range of the modern orchestra. While rooted in Classical balance and clarity, symphonies incorporate a wide spectrum of harmonic languages and orchestral techniques. From Haydn’s wit and structural innovation to Beethoven’s heroic scope, Mahler’s cosmic breadth, and Shostakovich’s modern intensity, the symphony has remained a central pillar of Western concert music.

Tango is a music and dance genre that emerged in the Río de la Plata region at the turn of the 20th century, characterized by its dramatic phrasing, bittersweet harmonies, and close-embrace dance. The music typically features an orquesta típica with bandoneóns, violins, piano, and double bass, playing in 2/4 or 4/4 time with a distinctive syncopated pulse derived from the habanera and Afro-Rioplatense rhythms. Its sound blends European salon dances (waltz, polka, mazurka), rural gaucho song (payada, milonga), and Afro-Uruguayan/Argentine candombe. Melodies often lean minor, with chromatic inner lines, lush diminished chords, and expressive rubato. Vocal tangos frequently use lunfardo (Buenos Aires slang) to tell stories of love, loss, and urban life.

Vocal jazz is the art of singing within the jazz idiom, emphasizing improvisation, rhythmic nuance, and personal interpretation of songs—often drawn from the Great American Songbook. Singers use jazz phrasing, swing feel, and timbral control to reshape melodies, bend pitches, and tell stories through the lyric. The style ranges from swinging uptempo numbers with scat improvisation to intimate ballads colored by subtle rubato and behind-the-beat delivery. While many vocal jazz performances feature small combos, the genre has also flourished with big band arrangements and sophisticated orchestrations.

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.
