Discovering Puerto Rican art song: a research project on four art song works by Héctor Campos Parsi
When a sports performance is at its peak, it is akin to a musical performance in the sense that each player seems to perform their part effortlessly, creating a rhythmic flow of counterparts all moving as one. Rhythm and timing are vital elements in sports like basketball in which syncopated passing and shooting appear to facilitate accuracy. This study tests if shooting baskets “in rhythm,” as measured by the catch-to-release time, reliably enhances shooting accuracy. It then tests if an “in rhythm” timing is commonly detected and agreed upon by observers, and if observer timing ratings are related to shooting accuracy. Experiment 1 tests the shooting accuracy of two amateur basketball players after different delays between catching a pass and shooting the ball. Shots were taken from the three-point line (180 shots). All shots were recorded and analyzed for accuracy as a function of delay time, and the recordings were used to select stimuli varying in timing intervals for observers to view in Experiment 2. In Experiment 2, 24 observers each reviewed 17 video clips of the shots to test visual judgment of shooting-in-rhythm. The delay times ranged from 0.3 to 3.2 seconds, with a goal of having some of the shots taken too fast, some close to in rhythm, and some too slow. Observers rated if each shot occurs too fast, in rhythm slightly fast, in rhythm slightly slow, or too slow. In Experiment 1, shooters exhibited a significant cubic fit with better shooting performance in the middle of the timing distribution (1.2 sec optimal delay) between catching a pass and shooting. In Experiment, 2 observers reliably judged shots to be in rhythm centered at 1.1 ± 0.2 seconds, which matched the delay that leads to optimal performance for the shooters found in Experiment 1. The pattern of findings confirms and validates that there is a common “in rhythm” catch-to-shoot delay time of a little over 1 second that both optimizes shooter accuracy and is reliably recognized by observers.
This piece experiments with different timbres and rhythmic motives. Timbral variety is achieved through grouping instruments into woods, metals, and membranes and using combinations of those groups to delineate different sections and ideas. The rhythmic motives are based on the numbers 3, 5, and 7, and appear as rhythmic values, phrase lengths, and number of repetitions.
The first section states a definition of rhythm and contains all timbres and motives contained within the composition. The piece then explores the relativity of time and is represented by drums changing the speed of their notes. The third section discusses rhythm as repetition and is illustrated by repetitive rhythmic motives. The text then features rhythm as a subjective human experience and is reflected through polyrhythms played between ensemble members. What follows is a description of meter as a temporal measurement that is unchanged by rhythmic activity. By bringing back previous motives, this section reveals that all of the motives work within the same meter. In the final section, the performers play various subdivisions of the beat to show different aspects of proportion by dividing the beat in several ways.
