harmonic minor, which contains a raised 7^th: l t d r m f si l^I or T S T T S T+½ S
(e.g. A harmonic minor: A B C D E F G♯ A), and
melodic minor, containing a raised 6^th and 7^th in the ascending octave which are lowered in the descending octave: l t d r m fi si l^I s f m r d t l or T S T T T T S|T T S T T S T
