Thrum

"I didn't even hear you down there!" a young composer admitted.

"Most people don't, and that's just fine," Thrum rumbled warmly. "I'm Thrum. I keep the bass — the deep floor the whole song stands on. I'm the lowest line in the music, the foundation under everything. I'm quiet and easy to miss. But take me away" — he stopped playing — "and listen."

The song suddenly felt like it was floating, wobbling, with nothing underneath. The young composers gasped. Thrum's low notes came back, and everything settled onto solid ground again.

Trill sang his motif up high. Thrum demonstrated: he played a deep, steady bass note that matched, and Trill's song felt grounded, sure of itself. Then Thrum wandered — playing low notes that didn't fit — and the whole song felt uneasy, like a floor tilting. "The bass doesn't just play low," Thrum said. "It plays the right low — the note that tells everyone where home is, down at the bottom."

A young composer thought hard. "So you're like the ground the song walks on?"

"The ground," Thrum agreed, pleased. "Trill flies up high and free because he knows the ground is steady beneath him. A melody can leap and dance only when something solid is holding the floor. That something is me."

The instructor asked Thrum to teach. "The students' pieces feel like they're floating away," the instructor said. "Their melodies have nothing underneath. Will you teach them to lay a floor?"

Thrum was glad to. When he teaches, he gives one rule: "Under your melody, add the lowest line — slow, steady, simple. It doesn't need to be busy. Often the bass just plays the strong, deep note that says here is home. Keep it solid. Let the melody fly above it. The simpler and steadier your floor, the higher your tune can climb."

A young composer added one deep, slow bass note beneath Trill's motif. Instantly the song stood up straight, sure of itself. "Trill sounds braver now," the composer said, surprised. "Because he's standing on something," Thrum rumbled. "That's the bass."
