Variations on the Theme A.D.M (for carillon)
Peter Paul Olejar, composer
Robin Austin, carillonneur
Rees Memorial Carillon
A.D.M. is a carillon piece based upon the letters "A, "D", and "M", the acronym for the Association of Disciple Musicians, to which the piece is dedicated.
The thematic material is based upon two types of cryptograms that are used to represent the letters A, D, and M
The first type of cryptogram is based upon a method, sometimes called the French method, where a motto is based up the letter note names, for example A through G. Letters further in the alphabet after G are assigned as if going up a scale higher than G and continuing the alphabet with H, I, J, etc. This would make an M sound as the note F, either natural or sharp. So the cryptogram motto for ADM consists of the notes A, D and F (sharp or natural).
The second type of cryptogram is a visual one. A visual cryptogram is one where the layout of the notes in the score resembles the letter. Once the listener knows what the sound of this visual layout is, then it becomes recognizable when used as thematic material in the piece.
The last reference is a cryptogram of the letters DISCIPLE found in the notes D, B, Eb, C, B, Bb, E, Eb. Notice that the Eb represents the letter "S" using the German name for Eb.
Two other references are found in the piece. One consists of references to part of a satirical piece by Steve Reinhardt called “The ADM Fight Song”, the cadential figure used for the text "We're the A.D.M." The other reference is to the song “Three Blind Mice,” music used for fun by the late Vera Entz for ADM Conference clinicians on Follies Night where she had them walk through a series of movements as she used in teaching music to her elementary school students.
The form of this piece is four movements played without pause. It begins with a short introduction of the note A followed by the visual cryptogram for A, the note D followed by the cryptogram for D, and the note F followed by the cryptogram for M. The first section consists of 6/8 dance variations on the A cryptogram which in places quotes the cadence in the "ADM Fight Song" "We're the A.D.M."
The second section is introduced by the note D and the visual cryptogram for D. The section continues as a slow movement with variations on the D visual cryptogram with references to the full ADM notes (A, D and F).
The next section states the DISCIPLE note cryptogram as a ground with variations on the ground. Two of the variations include quotes of "Three Blind Mice." The section ends with the notes A, D and M (F) and a variation on the ADM fight song cadence. The last section is introduced by the note F (for 'M') and the M visual cryptogram. It is a faster section marked "Jazzy" using variations of the visual cryptogram for M.
The coda references "Three Blind Mice" and the "We're the ADM" cadence.
