m#5 (m+5) chords
The Minor sharp 5th chord is an alternation of the minor chord. It's also referred to m+5, with a plus sign instead of a sharp, that is. This chord is identical to a minor triad except that the fifth is raised one step. By comparing Cm with Cm#5 we can see that the notes change from C, Eb, G to C, Eb, G#. This chord category should not be confused with the m7#5. Notice also that the minor #5 is identical with the second inversion of the major triad (for example, Em#5 is identical with C/E).
The m#5 is a uncommon chord and it's recommended to learn moveable shapes. Two alternatives are presented in the charts below with the root on either the 6th string or 5h string.
