text: C major consists of C , D , E , F , G , A , B , and the scale a semitone higher ( D major ) consists of D , E , F , G , A , B , C. When transposing a mode of limited transposition this is not the case . For example , the mode of limited transposition that Messiaen labeled `` Mode 1 '' , which is the whole tone scale , contains the notes C , D , E , F , G , A ; transposing this mode up a semitone produces C , D , F , G , A , B. Transposing this up another semitone produces D , E , F , G , A , C. Since transposing the mode up a whole tone produces the same set of notes , mode 1 has only 2 transpositions .
simplified: Transposing this up another semitone , starting on D , would give D , E , F # , G # , A # , C , D which is exactly the same combination of notes as the first one ( the starting note is not important ) .
