Update: Alternate Spellings for Minor Triads

This might not be technically correct as far as music theory goes, but we've updated several entries for minor chords with alternate spellings.  Our rationale is that the correct enharmonic might not register while playing within a scale that uses a different note name.

For example, the F minor chord consists of the F, Ab, and C notes.  The A harmonic minor scale is A, B, C, D, E, F, G#, and A.  The Fm chord exists in the A harmonic scale as the following notes:  F, G#, and C, where G-sharp is the enharmonic of A-flat.  When working within the framework of the A harmonic minor scale, it would be more convenient to use the G# note over the Ab note.  That's why we included these alternate, non-standard spellings of various minor chords, linked to below:

Fm:  Usually F-Ab-C; F-G#-C in A harmonic minor.
Cm:  Usually C-Eb-G; C-D#-G in E harmonic minor.
Gm:  Usually G-Bb-D; G-A#-D in B harmonic minor.
Dm:  Usually D-F-A; D-E#-A in F# harmonic minor.
Am:  Usually A-C-E; A-B#-E in C# harmonic minor.
Em:  Usually E-G-B; E-Fx-B in G# harmonic minor.
Bm:  Usually B-D-F#; B-Cx-F# in D# harmonic minor.
Cbm:  See Bm; in any case, usually Cb-Ebb-Gb; Cb-D-Gb in Eb harmonic minor.
Gbm:  Usually Gb-Bbb-Db; Gb-A-Db in Bb harmonic minor.
Dbm:  Usually Db-Fb-Ab; Db-E-Ab in F harmonic minor.
Abm:  Usually Ab-Cb-Eb; Ab-B-Eb in C harmonic minor.
Ebm:  Usually Eb-Gb-Bb; Eb-F#-Bb in G harmonic minor.
Bbm:  Usually Bb-Db-F; Bb-C#-F in D harmonic minor.
