In the middle of Homily 54 of his Ascetical Homilies, St. Isaac gives specific advice on how to do this, how to take delight in psalmody.

He begins by saying that one should disregard both the quantity of verses and the beauty or skill with which one recites them. According to St. Isaac, delight in psalmody has nothing to do with how beautiful the reading sounds nor with the amount of verses one recites.
