Enharmonic Pairs
Flip two cards at a time. Every card's match is the OTHER spelling of the same pitch — C♯ pairs with D♭, not with another C♯ — so find all six pairs in as few moves as you can.
Why this helps
- One pitch, two names. Sharps and flats are the same keys on a piano wearing different labels — matching them by sight is what makes key signatures and scales stop feeling arbitrary.
- Three pairs need no accidental at all. E♯, B♯ and F♭ each land on a plain white key — F, C and E — which is the part most players forget first.
