Chant Mozarabe: Cathedrale de Tolède (XVe siècle)

Spanish classical music refers to the art-music tradition created by composers active in Spain from the Renaissance to the present, encompassing sacred polyphony, court and theatrical genres, instrumental idioms for guitar and keyboard, and nationalist currents that elevate regional dance and song types. It is characterized by the coexistence of European common-practice techniques with distinctively Iberian colors: modal inflections (especially the Phrygian flavor), the Andalusian cadence, dance-derived rhythms (fandango, seguidilla, jota, bolero), and an idiomatic centrality of the guitar alongside choirs, keyboard, chamber, and orchestral forces. Across centuries, Spanish composers have contributed both to pan-European classical forms (mass, motet, sonata, concerto, symphony, opera) and to uniquely Spanish hybrids (zarzuela, tonadilla), while absorbing deep historical layers that include medieval chant, Renaissance polyphony, and interactions with Sephardic, Moorish/Andalusian, and folk–flamenco traditions.

Mozarabic chant (also called Old Hispanic or Visigothic chant) is a monophonic, unaccompanied liturgical repertory that served the Old Hispanic (Mozarabic) rite of Christian worship in medieval Iberia. It features free, speech‑like rhythm, modal melodic formulas, and a mix of syllabic, neumatic, and highly melismatic passages tailored to Latin liturgical prose and poetry. Its melodies were preserved in non‑staff neumes (Visigothic notation), which transmit contour and nuance but originally lacked precise pitch, making modern performance partly reconstructive. The sound is austere yet ornate, with solo cantors and a small schola alternating antiphons, psalm verses, and long responsories within a distinctive Iberian liturgical calendar and order.

Plainchant (cantus planus) is the monophonic, unaccompanied chant of the Western Christian liturgy. Sung in Latin (with occasional Greek), it uses modal scales rather than major–minor tonality and unfolds in flexible, speech-like rhythms shaped by the sacred text. Melodically, plainchant ranges from simple syllabic formulas for reciting psalms to ornate melismatic lines for processional and festal moments. It is performed in unison by a schola or congregation, often organized antiphonally or responsorially across the liturgical actions of the Mass and the Divine Office. Its austere sonority, modal color, and text-centered phrasing give it a contemplative, timeless quality.
