An enharmonic note is a note that has two names but have the same fingering
G, A#, B#, C#, D#, E# and Fx (I'm using all scale degrees for this). Fx is F double sharp which means 'F sharp sharp', which is the same as G.
I only know the intro to the song so far, and for the right hand only, but I . The right hand goes like this: Middle D, High D, Middle A, Middle G, High G, Middle A, High F Sharp, Middle A Middle D, High D, Middle A, Middle G, High G, Middle A, High F Sharp, Middle A Middle E, High D, Middle A, Middle G, High G, Middle A, High F Sharp, Middle A Middle E, High D, Middle A, Middle G, High G, Middle A, High F Sharp, Middle A Middle G, High D, Middle A, Middle G, High G, Middle A, High F Sharp, Middle A Middle G, High D, Middle A, Middle G, High G, Middle A, High F Sharp, Middle A Middle D, High D, Middle A, Middle G, High G, Middle A, High F Sharp, Middle A Middle D, High D, Middle A, Middle G, High G, Middle A, High F Sharp, Middle A play all the above twice and then play Middle D, High D, Middle A, Middle G, High G, Middle A, High F Sharp, Middle A Middle D, High D, Middle A, Middle G, High G, Middle A, High F Sharp, Middle A and that's the entire intro

If you are asking about the interval it is a minor third (or an augmented second...) In a Chromatic scale starting on C the tones are: C C#(or Db) D D#(orEb) so the whole step (two semitones) would take you from C to D, and then the half step would get you to D#(or Eb... they are enharmonic equivalents, which means that it's the same pitch with two different names)
D-flat
E natural
D sharp minor
Do you mean the note? An enharmonic of D sharp is E flat.
The enharmonic of a note is another note that sounds the same, so the enharmonic of d flat would be c sharp.
A double sharp is the enharmonic of B nature
F sharp is the enharmonic.
F sharp is the enharmonic.
It's called enharmonic spelling. An example is C-sharp and D-flat.
The enharmonic of E-sharp is F-natural.
The enharmonic tone for F is E sharp.
B flat
