Now anyone can learn to play the 10 strings Davidic Harp easily.

You just need to delight yourself in the Lord.

7But the Lord said to Samuel (Prophet), “Do not look at his appearance or at his physical stature, because I have refused him (Eliab).  For the Lord does not see as man sees; for man looks at the outward appearance, but the Lord looks at the heart.” (1 Samuel 16:7)

You also need to learn and practise on the Harp.

16Let our master now command your servants, who are before you, to seek out a man who is a skillful player on the harp. And it shall be that he will play it with his hand when the distressing spirit from God is upon you, and you shall be well.” (1 Samuel 16:16)
 
Finally, make yourself available to God as a Healing Harpist.
