Widor, Charles-Marie: Symphony No. 5 and No. 9

Organ music refers to repertoire written or improvised for pipe organ (and, by extension, other classical organs such as positive and portative). It spans sacred and secular contexts and includes liturgical accompaniments, free preludes and toccatas, contrapuntal forms (fugues, ricercars), chorale-based works, symphonic poems, and large cyclic forms. A defining trait is the organ’s orchestral palette: ranks and stops allow timbral combinations from whispering flutes to blazing reeds, supported by an independent pedal division that enables full, polyphonic textures. Across history, organ music has been closely linked to church ritual and acoustics, but it also developed into a concert tradition with virtuosic, architectonic forms that exploit large instruments in resonant spaces.
