seventh
   a unit used in music to describe the ratio in frequency between notes. Two notes differ by one seventh if the higher note has frequency exactly 15/8 times the frequency of the lower one. On the standard 12-tone scale, the seventh is approximated as 11 half steps, corresponding to a frequency ratio of 211/12 = 1.8877.
