A Proposal for Indicating the Duration of CPT Spatial Tension Signs

A Proposal for Indicating the Duration of CPT Spatial Tension Signs
Submitted by DNB Staff - April 6, 2006

The signs for Central, Peripheral, and Transverse Spatial Tension are shown in Ex. 1a-c.
 

The original sign for Transverse Spatial Tension did not contain an arrow, as in Ex. 1d. Jan Pforish adds an arrow to the Transverse sign to make it more consistent with the Central and Peripheral signs, and to keep it from looking like a “yin-yang” symbol. I like this idea, so in this posting I will use the Transverse sign shown in Ex. 1c.

A method of showing the time value of these indications has not been standardized. I suggest the following:

– A fast Spatial Tension is depicted with the sign by itself, as in Ex. 2a.

– The time value of the sign can be increased by connecting it to a duration line, as in Ex. 2b. Such indications make a literal statement, i.e., the given Spatial Tension occurs once, throughout the time indicated by the indication.

– Thematic Spatial Tension is indicated with the sign for the Tension inside a thematic bracket, as in Ex. 2c. Such indications depict a given Spatial Tension that occurs an unspecified number of times, throughout or intermittently during the unit indicated by the thematic bow. The overall timing of the thematic unit is shown by the length of the thematic bow.

– A Spatial Tension during stillness is indicated with the sign for the Tension inside an intention bow, as in 2d. The duration of the given Tension is shown by the length of the intention bow.

The indications can be used in Motif Notation as exemplified below.
