Psalm 33:1-4

Rejoice in the LORD, O ye righteous: for praise is comely of the upright.  Praise the LORD with harp; sing unto him with the psaltry and an instrument of ten strings.  Sing unto him a new song; play skillfully with a loud noise.  For the word of the LORD is right; and all his works are done in truth.

As a band director, I especially like the "play skillfully".  The part "with a loud noise", I assume means with good breath support.  However, the most important part is "the word of the LORD is right; and all his works are done in truth".
