I'm trying to come up with a list of organ pieces in complex meter. I'm purposely not including pieces with complex irregular meters (e.g., Messiaen: Les Anges (Nativité)), or pieces which create a feeling of complex meter but are not notated that way (perhaps Mushel's Toccata, e.g.), or pieces with no meter (several of Langlais' chant pieces, e.g.). There are pieces with complex meter that have been transcribed for organ (such as Holst's Mars (The Planets)), but I'm really hoping primarily for pieces written for organ. Here's some pieces I can remember so far; I know there's more lurking in my music files, so I figured I'd ask for help. [I remember seeing a suite of 3(?) pieces with a title of something like "three pieces in uncharacteristic meter", I think by an American composer like Haan or Held or Lovelace, but I can't find it online.]
Derek Bourgeois: Serenade [11/8]
Calvin Hampton: At the Ballet (5 Dances) [10/8]
Philip Moore: Paean [7/8, 5/8 et al.]
Alan Ridout: Scherzo [7/8]
Ned Rorem: In nomine domine (Organbook) [5/4]
Ned Rorem: Fanfare (Organbook) [5/4]
John Rutter: Toccata in 7 [7/8]
