This is a 4-part arrangement of an old Welsh folk tune "Hyfrydol", which has been used as the setting for such hymns as "Alleluia! Sing to Jesus", "Love Divine All Loves Excelling", and "Jesus, What A Friend for Sinners".  Each part is geared towards a different skill level (drone-style melody for beginners; backup chords for advanced beginners; chord/melody style for intermediate players; harmony/counter-melody for more advanced players), making the arrangement suitable for clubs or other larger groups of players.
