Description
Guitar Hero III and similar games potentially offer a vehicle for improvement of musical rhythmic accuracy with training delivered in both visual and auditory formats and by use of its novel guitar-shaped interface; however, some theories regarding multimedia learning suggest sound is a possible source of extraneous cognitive load while playing so players may score higher with sound turned off. Also, existing studies have shown that differences in the physical format of interfaces affect learning outcomes. This study sought to determine whether (a) the game’s audio content affects rhythmic accuracy, and (b) the type of game controller used affects learning of rhythmic accuracy. One hundred participants were randomly assigned in approximately equal numbers (ns = 25) to the four cells of a 2x2 between-subjects design. The first variable was the audio content of the game with two levels: on or off. The second variable was the type of game controller: the standard guitar-style controller or tablet interface. Participants across all conditions completed a pre- and post-test with a system that required them to tap along with repeated rhythmic patterns on an electronic drum pad. Statistical evidence showed better outcomes with a tablet controller with respect to input time error, reduction of extra notes played, and reduction of missed notes; however, the guitar-style controller produced superior outcomes in terms of avoiding missed notes and was associated with higher satisfaction by participants. When audio was present better outcomes were achieved at multiple factor-levels of reduction of missed responses, but superior outcomes in input time error were seen without audio. There was no evidence to suggest an interaction between controller type and the presence or absence of audio.

Description
Rhythm is a work for percussion ensemble and narrator. The percussion ensemble includes five percussionists who each play multiple instruments. The narrator recites quotes from the book Meter as Rhythm by Dr. Christopher Hasty. The piece is in six parts with a short introduction (mm. 1-5). The structure is delineated by the quotes from Meter as Rhythm. The narrator describes an aspect of rhythm at the beginning of each section and the quote is sonically realized through the percussion ensemble.
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.

Description
Languages have long been studied through the rhythm class framework, which discriminates them into separate classes on the basis of shared rhythmic properties. Originally these differences were attributed to the isochronous timing of different prosodic units, such as stress intervals in “stress-timed” languages and syllables in “syllable-timed” languages. More recent work has turned to durational metrics as a means of evaluating rhythm class, by measuring the variability and proportion of segmental intervals in the speech stream. Both isochrony and durational metrics are no longer viewed as correlative with natural language rhythm, but durational metrics in particular have remained prevalent in the literature. So long as the conclusions of durational metrics are not overextended, their analysis can provide a useful mechanism for assessing the compatibility of a language with a given rhythm class by way of comparative analysis. This study therefore presents a durational-metric comparison of Scottish Gaelic, a language which has frequently been described as stress-timed but has never been empirically tested for rhythm class, with English, a prototypical and well-studied example of a stress-timed language. The Gaelic metric scores for %V (percentage of vocalic content), ΔV (standard deviation in vocalic interval length), and ΔC (standard deviation in consonantal interval length) (Ramus et al. 1999) are shown to be very similar to those measured for English, indicating that the language displays similar patterns of durational variability and segmental proportion typically ascribed to a rhythmically stress-timed language. This provides clear support for the classification of Scottish Gaelic as stress-timed.
