Are you playing it on a piano? It was written for it.
No.
.... calling a piece a song just is what it is; ..... It doesn't make a g*ddamn difference.
How would you feel if your doctor said he's going to "cut you open with a sharp knife and fix some stuff" instead of saying he's going to "perform a coronary artery bypass procedure to unclog your arteries"? I'd trust the doctor who used the big fancy terms that I don't understand.
It is quite important when we are talking music because the definition of a song is something that is meant to be sung by the voice. Unless you think a piano is like a voice, but that is a little strange. ...I don't know many serious pianists who could consider playing HR2 calling piano pieces songs anyway. ...
I've always agreed with this analysis, yet it leads to a logical conundrum:Mendelssohn's "Lieder Ohne Worte" (Songs Without Words) written for the piano.Maybe it's the "exception that proves the rule".
