The Whistle Maker's Two Branches

Nilo promised the hill-town dancers a willow whistle before the lantern fair. His teacher had left two straight branches on the bench and marked a possible opening on each. Nilo wanted a bright note that could rise above the dancers' steps. On the first branch, he widened the opening quickly and tested it only after several large cuts. The whistle answered with thin breath instead of a steady tone. More carving could not restore the wood already removed.

Only one branch remained. Nilo was tempted to copy every measurement from a finished whistle, but the two pieces of wood did not have exactly the same shape. Instead, he made one small change, cleared the shavings, and listened. After each test, he decided whether the next cut was needed. The tone grew clearer, then settled comfortably between the low hand drum and a row of little bells. Although one pencil mark remained, Nilo stopped carving.

At the fair, the whistle gave the dancers their entrance and carried the tune without covering their steps. Nilo kept the failed branch above his workbench rather than hiding it. When a younger apprentice later asked about it, Nilo prepared several scraps for practice. He explained that a careful maker leaves room for evidence to change the plan. The apprentice expected a secret measurement; instead, Nilo taught the harder skill of knowing when enough wood was gone.
