What are the piano notes to we three kings?

In the key of C major (or A minor) the first part is as follows: E D C A B C B A E D C A B C B A C C D D E E G F E D E D C B A

B D C C C G C A C C C C G C A C C C D D E E G F E D E D C B A

Be careful how you read the notes above. Some will be below the C note, others above.
