The ''two-semitone tritone scale'', C D{{music|flat}} D F{{music|sharp}} G A{{music|flat}}, is a [[symmetric scale]] consisting of a repeated pattern of two semitones followed by a major third now used for improvisation and may substitute for any mode of the [[jazz minor scale]].<ref name="Dziuba">Dziuba, Mark (2000). ''The Ultimate Guitar Scale Bible'', p.129. {{ISBN|1-929395-09-4}}.</ref> The scale originated in [[Nicolas Slonimsky]]'s book ''Thesaurus of Scales and Melodic Patterns'' through the "equal division of one [[octave]] into two parts," creating a tritone, and the "interpolation of two notes," adding two consequent semitones after the two resulting notes.<ref>{{Cite book|url=https://books.google.com/books?id=RiYPAAAACAAJ|title=Thesaurus of Scales and Melodic Patterns|author=Nicolas Slonimsky|author-link=Nicolas Slonimsky|date=22 December 2000|publisher=Music Sales Corp.|isbn=0-8256-7240-6|access-date=Jun 2, 2009}}{{Page needed|date=June 2009}}</ref> The scale is the fifth mode of [[Modes of limited transposition#Messiaen.27s list|Messiaen's list]].
