The optional WAV cue is 3.2 seconds, mono, 16 kHz, 16-bit PCM. It has eight equal 0.4-second slots, made with original sine-wave tones, no recording or copyrighted sample. Play at low volume only with a willing audience; the score below supplies all instructional information without sound. The first/second layers differ in pitch; pitch is not a culturally coded motif or a tune copied from elsewhere.
| Beat | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
| Layer A, lower tap | X | rest | X | X | rest | X | rest | X |
| Layer B, higher tap | rest | rest | rest | rest | X | rest | X | rest |
Text narration: “Lower tap; silence; lower tap; lower tap; higher tap; lower tap; higher tap; lower tap.” Each tap is short, followed by space within its 0.4-second slot. To make a tactile score, use eight large numbered boxes and two rows of raised or removable tokens; an empty box means rest. Learners may point or direct another person. Do not require touching, hearing or producing sound to discuss timing, entry and texture. A score documents composition; an actual performance needs observation.
Day 16's 0, 800, -800, 0 are illustrative integer samples for a paper plot, not an extraction that can reconstruct this complete WAV. The cue uses thousands of samples per second. The source and rights ledger records original authorship and licence.
