Design a sonic signature from household sounds

Design a four-second sonic signature for [BRAND CHARACTER] using only [THREE HOUSEHOLD OBJECTS] and optional original humming. Provide the rhythm as syllables, a layer-by-layer cue sheet, approximate pitch contour, recording setup and two alternate endings: warm and energetic. Explain how it remains audible on a phone speaker and how to leave space for spoken brand name added later. Do not imitate a known sonic logo, song melody or performer. Output a concise production brief plus a reproducible human recording recipe; do not claim the sound file has been created.
