One thing 당신 must always remember is the treble clef line is obviously the melody and is played with your right. It also is usually what a singer would be following as well. a good way to remember the notes is Every Good Boy Deserves 퍼지

then the line below it is base clef which is played with the left hand and is the harmony.

Try playing just the melody 또는 just the harmony at first till 당신 get used to it then add both. Its not too confusing once 당신 get used to it trust me.
Another thing that could help is learning pitches with your ears as well. A finely trained ear can always help you. Especially if 당신 know the song.
