Was Jesus good at singing? At Matthew 26: 27-30 we see:


  Then he took a cup, and after giving thanks he gave it to them, saying, “Drink from it, all of you;   for this is my blood of the covenant, which is poured out for many for the forgiveness of sins.   I tell you, I will never again drink of this fruit of the vine until that day when I drink it new with you in my Father’s kingdom.” When they had sung the hymn, they went out to the Mount of Olives.


That is perhaps, the only narrative in the Gospels where we see Jesus singing.  There is a school of thought which says that Jesus taught many things, including the Lord's Prayer, in verses. The Catholic Church is yet to come up with a confirmatory statement on the said prospects. Be that as it may, I am eager to know if Jesus was good at singing, just as his forefather David was. Does any apocryphal teaching endorsed by the Catholic Church say that Jesus was good at singing ?
There is no information on the quality of Jesus' singing

The Catena Aurea includes commentaries on this verse from Origen, Bede, Rabanus, Chrysostom, Hilary, and Jerome and not one of them talk about the quality of Jesus' singing. No other commentaries I found talked about Jesus quality of singing either, nor made reference to any extrabiblical traditions.

On the contrary, Isaiah 53:2 (NIV), which Christians say describes Jesus, says as follows:


  He grew up before him like a tender shoot, and like a root out of dry ground. He had no beauty or majesty to attract us to him, nothing in his appearance that we should desire him.


While this passage is referring to his physical appearance being unremarkable, it would follow that "he had no beauty or majesty to attract us to him" also with regards to his singing ability.
