At each lesson, our harp teacher Jane Hawkins emphasizes the importance of "pretty hands." At first, I thought it was purely for aesthetics. But now, I know that "pretty hands" is actually good hand position that enables you to properly pluck strings and maintain good tempo.
Playing with "pretty hands" looks easy, but after four months of practice, neither Dad nor my daughter have yet to master it. The difference in ability and motivation between student and teacher is like the NFL commercial I've seen on TV: "Amateurs practice until they get it right; professionals practice until they never get it wrong."
Interestingly, Psalm 33 encourages musicians to master good fundamentals, for in doing so it inspires worship:
1 Sing joyfully to the LORD, you righteous; it is fitting for the upright to praise him.
2 Praise the LORD with the harp; make music to him on the ten-stringed lyre.
3 Sing to him a new song; play skillfully, and shout for joy.Whatever you do--at home, at work, at school, or at church--strive for excellence. God appreciates it. And you will too.
