Is there a Do Re Mi Fa Sol La Ti Do equivalent in the minor scale? If so how's it spelled and how's it sung (maybe someone has a link where someone sings it). Thanks
First off, this notation is known as Solfege, and there are two different types. Fixed Do, where C is always Do, and Movable Do, where the root of the scale you are using is Do. The rest of this answer will focus on Movable Do, as in Fixed Do the answer will differ based on what note you are starting on.
The major Solfege syllables are the ones that you listed (note, sometimes
Ti is called
Do Re Mi Fa Sol La Ti Do
The chromatic Solfege syllables are as followed with
i typically raising a note and
etypically lowering a note with the exception of Re that lowers into Ra:
Do Di/Ra Re Ri/Me Mi Fa Fi/Se Sol Si/Le La Li/Te Ti Do
To get any other scale just lower or raise the syllables as you would notes in the scale, so for natural minor Movable Do you get:
Do Re Me Fa Sol Le Te Do
You can treat the minor tonic as Do of its own scale. Or you can treat it as La of the relative major. Either way, (for anything but the Natural Minor with La as tonic) you'll need 'accidentals'.
There are several systems of doing them in solfege. Here's one:
The sharpened degrees are sung as Di ('Dee'), Ri, Fi, Si, Li. (There seems no need for a sharpened 3rd).
The flattened degrees are Raw, Maw, Saw, Law, Taw.
So, a harmonic minor scale would be Do, Re, Maw, Fa, So, Law, Te, Doh. Or, in the 'relative' system: La, Te, Do, Re, Mi, Fa, Se, Do.
Here's (the beginning of) a discussion of this controversy from 1888, over 100 years ago!
