What does it mean to sing off key?

Answer 1

When somebody "sings off key" it means they are singing out of the designated key signature. Take the key of C for example. This key has no sharps or flats(on the piano this means only using the white keys). So if someone is signing off key in the key of C they'll sound bad because the notes being sung aren't harmonious. Your ear is trained and accustomed to music that's played or sung in the same key. Even those who don't know much about Music Theory can detect a variance from the key signature. Just as someone who doesn't know much about makes and models of cars can tell you which one is newer. Hopefully this answers your question. On a side note, if you were being accused of singing off key, tell them you were going for the dissonant harmony. That should shut 'em up. lol
