[sound info]
In 17-limit just intonation, 17/9 is the large septendecimal major seventh, measuring about 1101¢. It is the mediant between 15/8 and 2/1. Its inversion is 18/17, the "small septendecimal semitone".
There exists a disagreement in different notation systems on whether 17/9 should be notated as a major seventh or a diminished octave. In the Functional Just System, it is a diminished octave, whereas in Helmholtz-Ellis notation, it is a major seventh.
