My name is Paul Sandberg. I'm an Actor, Singer and Teacher in the New York city Area. For more information please visit my website at paulsandberg.net. That's Franz Schubert's "Ave Maria" sung in Latin not necessarily just a christmas piece actually. I hear this all year around often at weddings. The trickiest part of this song is that (well besides that everybody knows it) you have just patern your lline in the right hand which is really mostly just different inversions of the main chords. This is being A flat. You can get away however if you would like an easier time on the song with cutting out that pattern all together and just playing the melody in your right hand. So that would kinda sound like, starting right on ave maria. Actually you don't have to play the right hand if you don't want to. And that's how you can play Ave Maria on the piano. Resist the urge that sounds too much like Bing Crosby.
