Le Concert d'Astrée

Musique ancienne (French for “early music”) denotes the historically informed performance of medieval, Renaissance, and Baroque repertoire on period instruments and with period-specific techniques. Rather than a single historical style, it is a practice and aesthetic: performers consult original sources, treatises, and surviving instruments to recreate articulation, ornamentation, tuning, tempo, and ensemble balance as they likely sounded before the Classical era. Hallmarks include gut strings, low and flexible pitch standards (e.g., A=415 for Baroque, variable for Renaissance/medieval), meantone or well temperaments, natural trumpets, cornetts and sackbuts, recorders and traversos, theorbos and lutes, viol consorts, organo and harpsichord continuo, and an emphasis on dance rhythms and text-driven phrasing. Today the term also implies an interpretive ethos—clarity of counterpoint, rhetorical delivery, and stylistic diversity across centuries—applied to sacred and secular works from monody and polyphony to dance suites, madrigals, and early opera.

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.

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.
