I'm reading from the NKJV.
   In looking at these verses, you can see that God is making a statement
to the king of Tyre.  But, common sense tells us that it is not possible
for the king of Tyre to have been present in the Garden of Eden.
Therefore we must decide who God is actually addressing in this passage.
   If you read from 13-19, it is quite plain to see that this is Lucifer,
i.e. Satan.  Who else, having these traits, would have been found in the
Garden of Eden?  There were no others in the Garden than Adam, Eve, God,
and the Serpent, a common reference to Satan, mentioned in the bible,
excluding animals, plants, ect.
   Anyway, the reference for music is in verse 13, and I quote "The
worksmanship of your timbrels and pipes was prepared for you on the day
you were created."  Holding the highest angelic position in heaven until
he fell, Lucifer was the leader of the praise and worship services in heaven!
:)  

   I hope that clarifies things some.  Ask more questions.  I'm willing to
answer.  :)

   I am being placed in a position to either damn or
      bring to salvation many people.  
   Either way, I will serve the Lord as He calls me,
      but I pray it may be to salvation.
