bamboo flute, whistle
篴 centers on a simple wind instrument made from bamboo: a flute or whistle. The meanings are closely related, both describing a tubular bamboo device that produces sound when blown.
篴 combines 竹 (bamboo) with 逐, which likely provides the sound. The character originally referred to a bamboo flute, and the phonetic component 逐 suggests the reading.
The top bamboo radical 竹 hints at the material, and the bottom 逐 looks like a person chasing something. Imagine a bamboo flute whose sound chases away silence, producing a clear whistle.
For テキ, picture a bamboo flute playing a sharp, quick note that sounds like 'tek'—a short, crisp whistle. The 'tek' sound cues テキ, and the flute makes the note.
