tridecimal augmented fourth
[sound info]
In 13-limit just intonation, 18/13 is a low tritone measuring about 563.4¢. It represents the interval between the 13th and 18th harmonics of the harmonic series. The low tritone in 17edo approximates 18/13 quite well, while 17edo's approximations of 13/8 and 9/8 are both a little sharp. The inversion of 18/13 is 13/9, a high tritone measuring about 636.6¢; the interval between these two tridecimal (13-based) tritones is 169/162, approximately 73.2¢.
