| - | If music can encourage stimulus synchronous respiration, what part of the respiration cycle is being aligned to the music? | + | If music can encourage stimulus synchronous respiration, what part of the respiration cycle is being aligned to the music? Using respiration band stretch data from one listener recorded during multiple listenings (24) to the same set of musical stimuli (25), significant coordination has been measurable on inspiration onsets for some pieces. The follow explains how coordination to other parts of the respiration cycle were evaluated. |

| - | The Figure shows three representations of the same respiration band stretch data from a single listening. First is the filtered stretch sensor data reported over time; each breath takes a few seconds, inspiration during the rise in value, exhilation during the fall, and period of relative stability of variable length in bet ween. Second is the onsets of inspiration, as selected by my less than perfect detection algorithm which selects local minima, calculates the duration of time between them, and excludes those which are too close together. And last is the approximate phase values, mapping the respiration cycles to the interval [0,1] by fitting the model cycle to the sensor data between inhilation onsets. | + | The figure below shows three representations of respiration from the subject during the presentation of a single piece of music.
