There's a lesser form of tone-deafness (perhaps that's not the right word for it) where you can't tell with certainly or consistency the direction or extent of a change in pitch.
You can still hear and appreciate music, but you can't whistle or hum along to a tune.
I know someone who can sing to match a melody from memory very accurately. They sing on key. But they have a hard time singing to match a single pitch, and they have a very hard time naming whether two consecutive pitches are ascending or descending.
