Case Study 2 participants' effort-shape observations across the duration of the performance material. The minor gridlines show the 2 s bins that were examined for agreement between the vocalist and percussionist for the same type of action in each category (basic effort actions, transformation drives, and shape features). Shared “Dab” observations (n = 10) reflect 31.24% of all “Dab” observations, and 13.16% of all basic effort action observations. Shared “Rising” observations (n = 3) reflect 7.14% of all “Rising” observations, and 5.08% of all shaping feature observations. The shared “Glide” observation (n = 1) reflects 7.14% of all “Glide” observations, and 1.32% of all basic effort action observations. Agreement results for observations of the same type of action at the same location in the performance material are reported in a previous publication (see Broughton and Davidson, 2014).
