NOT.8:5 - Archetypal Grounding

NOT.8:5.1 - Recover a cue’s place in a beat

Choose a beat divided into four equal positions. In the Takadimi convention these positions are voiced as ta, ka, di and mi. For this example, a dot in the written grid means no new onset at that position; it does not specify how long an earlier sound continues.

Establish a steady beat, divide it into four and keep the beat’s start identifiable. The first pattern has onsets at 0 and 1/2. A shift of one quarter-beat, within this one-beat example, yields onsets at 1/4 and 3/4. The new syllables identify the new positions. Repeating the same two spoken syllables without their reference would not express this change of placement.

At a beat duration of one second, the first onsets occur at 0 and 0.5 seconds; the shifted ones at 0.25 and 0.75 seconds. At a beat duration of half a second, the corresponding times halve while the relative positions remain. A requirement for an onset at an absolute 0.5 seconds is therefore a different requirement.

If the sound between two known positions is unrecorded, do not replace that gap by a written dot claiming no onset. Preserve the missing-observation status. If the next operation asks how long notes are held, add the needed duration convention: the onset grid alone does not answer it.

This is a notation construction, not a claim that reading the table teaches fluent rhythmic performance. Maintaining the beat and coordinating speech are available skills or contributions to be learned.

NOT.8:5.2 - Read a movement relative to a changing body frame

A tabletop movement score uses two signs. R means move one grid unit to the performer’s right without turning; F(2) means move two units forward without turning. The signs describe successive completed displacements. The starting position is (0, 0), with east as positive x and north as positive y.

A performer initially facing north reads R; F(2) as an eastward unit displacement followed by two northward units. The endpoint is (1, 2). The reading procedure first recovers the starting orientation, translates each body-relative direction into the grid frame, updates the position and continues from there.

Now the performer starts facing east. The same score yields one unit south and two units east, ending at (2, -1). Treating R as page-right would give a different route. If the intended task is to preserve the original grid-space path regardless of orientation, choose a grid-relative notation or construct the appropriate body-relative instructions; keeping the marks unchanged does not meet that new task.

The score leaves the speed and path within each displacement unspecified. It can guide a prepared person moving a token. Making a physical robot perform it additionally requires an applicable motion method and an account of its realization. Reading the endpoint establishes neither that method nor a performed movement.
