Look at
http://www.letsreadgreek.com/songs/default.htm. There are currently no Christmas songs. The web page is a little out of date (it's my site and there are a whole slew of songs not posted). Do you have any requests? I know of no other site than mine which deals with songs. Mounce has a couple in his new edition, I hear.
Here's a try at Silent Night:
Silent night! Holy night!
All is calm all is bright
Round yon virgin mother and child
Holy infant so tender and mild
Sleep in heavenly peace!
Sleep in heavenly peace!
ἡσύχη νῦξ
ἁγία νῦξ
πάντ' ἠρεμεῖ
πάντ' ἀστράπτει
περὶ τῶνδε
-- τῆς μητρὸς καὶ τέκνου
-- βρέφους οὗ κεῖτ' ἤπιός τε καὶ πράϋς
κοιμῶ ἐν ὕπνῳ ἠπίῳ
κοιμῶ ἐν ὕπνῳ οὐρανίῳ
Here is a variation:
νῦξ ἡσύχη δή
νῦξ ἁγία δή
πάντα τ' ἠρεμεῖ
πάντα τ' ἀστράπτει
περὶ τῶν δύο
-- τῆς μητρὸς καὶ τέκνου
περὶ τοῦ βρέφους ὅς ἐσθ' ὡς γε πραῧς
κοιμῶ ἐν ἠπίῳ ὕπνῳ
κοιμῶ ἐν οὐρανίῳ ὕπνῳ
Any suggestions?
