Analysis of Snare Drumming Technique via Applied Linguistic Theory
The research for motion capture analysis of snare drumming technique (IRB #2016-02-0031) applies aspects of linguistic theory to the displacement data derived from the motion trackers found on the subjects. The Vicon Motus system allows for an analysis of snare drumming technique via a 3D coordinate plane. This 3D data gives insight into the movement patterns of the snare drummers analyzed under the IRB project. Unless stated otherwise, all data will contain only the Right Shoulder, Elbow, Ulna, and Radius anatomical markers. Additionally, the data used in the analysis is transformed where the median value of each vector is set as approaching zero.
The Positions and the Basic Strokes: Experiment Date 4.23.16
As stated previously, the positions are not a set value for displacement; but a range of values which correspond to elements within the five number summary found in statistics. For instance, all of the trails for snare drumming in this experimentation contain three positions: up, tap, and rest position. In each trail, the values for the positions differ. Additionally, the tap stroke and buzz stroke has unique ranges of values for each position due to the nature of the minimal movement required to perform each stroke; so there will be two averages of positions: one with the tap/buzz stroke values and one without.
