19/17 is the interval between 9/8 and 10/9, two common sizes of whole tone. In meantone systems, the two are conflated into one interval, which converges increasingly closely to a perfect 19/17 in successive steps of the golden meantone sequence. Two of them fall short of a perfect 5/4 by 1445/1444, or 1.1985 cents.
19/17 is the mediant of 9/8 and 10/9: (9+10)/(8+9)=19/17.
