Elisha couldn’t get focused on the task at hand. His thoughts were running rampant. 

So he asked for music to be played.
The music calmed him. It also ushered in the hand of the Lord.
He then spoke according to the Word of the Lord.
When I have trouble focusing on the Word I try Elisha’s tactic. I pull out my iPod, listen to God glorifying music and allow the Lord to work within me. 
The method still works all these thousands of year later.
