Maîtrise de Notre-Dame de Paris

Classical organ refers to the Western art‑music repertoire written for the pipe organ, from its Renaissance emergence through Baroque, Romantic, and modern idioms. It is closely tied to the history of the pipe organ in churches and concert halls, whose basic design has been in use for over two millennia and became firmly associated with Christian worship by the 10th century. Stylistically it spans contrapuntal forms (toccata, prelude & fugue, chorale prelude), liturgical pieces, and concert works up to the 20th century, where Romantic “symphonic” organs enabled orchestral color on a single instrument and later modernists expanded harmony and rhythm. The repertoire’s expressive range runs from intimate, chant‑inspired meditation to large‑scale, architecturally resonant canvases exploiting 32′ basses, multi‑manual contrasts, and richly colored reeds and mutations typical of French and German traditions.

Gregorian chant is the central Western tradition of plainchant: a monophonic, unaccompanied sacred song in Latin (and occasionally Greek) used in the Roman Catholic liturgy. It employs free rhythm guided by the prosody of the text rather than by strict meter, and is sung in unison by clerics or scholas. Its melodies are organized by the system of eight church modes, with characteristic finalis (final), tenor/reciting tones, and melodic formulas. Repertoires include the Proper and Ordinary of the Mass (e.g., Introit, Gradual, Alleluia, Offertory, Communion, Kyrie, Gloria, Credo, Sanctus, Agnus Dei) and the Divine Office (e.g., Antiphons, Responsories, Hymns, Psalms). Although legend credits Pope Gregory I, modern scholarship sees Gregorian chant as a Carolingian synthesis of Old Roman and Gallican chants, standardized across Frankish realms and later the broader Latin West.
