'''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 interval between [[9/8]] and [[10/9]], two common sizes of whole tone.

19/17 is the [[mediant]] of 9/8 and 10/9: (9+10)/(8+9)=19/17. | |||
