The classical piano music works I dislike the most are the ones that pretend to be mice chasing each other, horses galloping, toy solders marching, or simply fields of buttercups.
Fellow Stumblers: I suspect there are no quick answers to sight-reading classical piano music and perhaps also no magical moment where sight-reading just happens (though I sometimes dream there is). I do know that it does gradually get better.
My piano teacher said something useful (she often does). She said, “I don’t pay any attention to black or white notes, because they are all the same.”
