Both are strongly dissonant intervals, the major seventh pulling to resolve upward, the minor seventh to resolve down. See also seventh chord .

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.
