These are four Christmas songs or Weihnachtslieder typical from Germany.
The four files correspond to the following Lieder:
GLOECKCH.AMS ....... Kling, Gloeckchen, kling!
NOCHEPAZ.AMS ....... "Stille Nacht, heilige Nacht!" or "Noche de paz" in Spanish ("Silent night, holy night")
ODUFROEH.AMS ....... "O du froehliche, o du selige!"
OTBAUM.AMS   ....... "O Tannenbaum!"
I entered the four songs in four voices each, although they actually should use more voices (six or seven).
Even so, they sound very nice. Enjoy them next Christmas!
