Subject: The 18 qujus scales
By a qujus scale I mean a Fokker block with commas a QUartertone of
36/35, a JUbilee comma of 50/49, and a Septimal comma of 64/63. Below
I list all 18 of them, in order of decreasing Lumma stability. On the
line describing it, the first number is the minimum maximum Tenney
height over all the transpositions, where the transposition chosen is
the unique one giving the minimax height. The next four numbers,
seperated by commas, are the number of o/utonal tetrads and
supermajor/subminor tetrads. There are always two each of the otonal
and utonal tetrads, but some scales have one subminor and supermajor,
and some have two. Following this is the ratio between the largest
and smallest scale step, then the lumma stability and finally
propriety. The first listed scale, qujus1, is clearly the most
regular, and is equivalent under transposition to
parizekj1.scl, "Petr Parizek, 12-tone septimal tuning, 2002" in
Manuel's database.
