'''10WTN''' is the [[EDF|equal division of the just perfect fifth]] into five parts of 140.391 [[cent|cents]] each alternated with a sequence of five equal steps of another interval between 120 and 160 cents in its patent tunings.  
'''10WTN''' is optimally the [[EDF|equal division of the just perfect fifth]] into five parts of 140.391 [[cent|cents]] each alternated with a sequence of five equal steps of another interval between 120 and 160 cents in its patent tunings. It is also the smallest wtn with two patent tunings which alternate an [[EDO|edo]] and an *ed(9/8).
