19/11, the undevicesimal semitwelfth is a 19-limit interseptimal interval measuring about 946 cents. It is classified as a minor seventh in FJS and HEJI, flat of the Pythagorean minor seventh by 176/171, which is the difference between 33/32 and 513/512. It can also be called the maximal major sixth in analogy to its inverse 22/19, in which case it is sharp of the Pythagorean major sixth by 304/297. A stack of two 19/11's falls short of 3/1 by 363/361.
