You'll be inundated with advice, but here's my tuppenceworth:

D sharp maj and E flat maj are the same, just called either according to the key.


So you can: move a D maj up one fret or an E maj down a fret.

However, you can only play fretted strings as you move the basic shape ( no strings left open).

If you can play a D hape but add pinkie to string4 at fret above finger 3 and omit strings 5 and six, that is easiest.
