The canopy opens just enough to let rain thread through, turning leaves into soft drums. You can hear the steady rhythm of rain-1-a drumming on broad leaves while dry-bamboo-3-b adds gentle wooden percussion. A distant brook-1-a whispers through mossy stones, and the occasional low-thunder-2-a rumbles like distant satisfaction. This is the moment when study finds its natural rhythm—focused, unhurried, perfectly balanced between earth and sky.
