tunes up

If folks on earth heard these tunes up in the air, I wonder what they'd think?

I wonder what they're actin' out, singin' hymn-tunes up in the barn chamber?

"Well, here's where th' orchestry tunes up, all right," he muttered grimly.

Just as a man thinks a woman is stronger than a lion she tunes up and cries.

Still, I would be the last to deny that it tunes up the system.
