|Subminor 6th
|Subminor 6th
|A noticeably flatter and darker version of a minor 6th.  May in some cases be mistaken for a very, very sharp type of 5th, but the obvious tonal color the interval provides is usually a start contrast to the stable concordance of a typical perfect fifth.  With the exception of the very flat end off the subminor 6th spectrum, intervals in this category are noticeably more concordant than sub-5ths.
