시벨리우스: 남성 합창과 오르간을 위한 프리메이슨 의례 음악, Op. 113 (Masonic Ritual Music, for male chorus and organ, op. 113)

Late in his career from 1925 to 1931, the Finnish composer Jean Sibelius wrote six pieces for solo organ, chronologically as follows: Intrada, Op. 111a (1925); Preludium and Postludium, JS 153/1–2 (1926); Avaushymni (in English: Opening Hymn) and Surumarssi (in English: Funeral March; in French: Marche funèbre), respectively Nos. 1 and 10 from the Op. 113 Masonic Ritual Music (Vapaamuurareiden rituaalimusiikkia; 1927, revised 1948); and Surusoitto (in English: Funeral Music), Op. 111b (1931). Of the six, the most important and oft-recorded is Intrada, which over the decades has become "something of a display piece" for domestic organists.
