Earlier, you said perfect pitch was unnecessary but that relative pitch is important. Do you think you could "teach" me relative pitch? I've been playing piano for 11 years but I'm still pretty bad at it.
i'm not sure if that's quite what i said. but i have been comfortable with pitch relationships for as long as i can remember. the way to learn it is to just sit at the keyboard (or any instrument) and get familiar with how the notes sound, relative to each other. if that is not working then i don't know what to suggest
