Music Memorization

Mental practice (MP) in music refers to the ability to rehearse music in the mind without any muscular movements or acoustic feedback. While previous studies have shown effects of the combination of MP and physical practice (PP) on instrumental performance, here we aimed to assess MP and PP effects on memory abilities. During a 1-week music practice protocol, classical guitarists were asked to practise a new musical piece using either a combination of MP and PP or PP alone. We asked participants to perform the piece and notate it at 3 different times: Day 1 and Day 7 of the 1-week practice protocol and 10 days after its completion (follow-up session). Results showed that the combination of MP and PP improves both notation and performance tasks compared with PP alone. Furthermore, we observed a clearer difference in memory performance in the follow-up session as compared with that in Day 7. Our results show that musicians can use both MP and PP to improve long-term retention and to reduce physical workload and playing-related overuse injuries. Therefore, we encourage music educators to teach MP in the classrooms rather than letting students discover it in a serendipitous way.

Abstract. A comprehensive calibration procedure for mobile, low-resolution, solar-absorption FTIR spectrometers, used for greenhouse gases observations, is developed. These instruments commend themselves for campaign use and deployment at remote sites. The instrumental line shape (ILS) of each spectrometer has been thoroughly characterized by analyzing the shape of H2O signatures in open path spectra. A setup for the external source is suggested and the invariance of derived ILS parameters with regard to chosen path length is demonstrated. The instrumental line shape characteristics of all spectrometers were found to be close to nominal. Side-by-side solar observations before and after a campaign, which involved shipping of all spectrometers to a selected target site and back, are applied for verifying the temporal invariability of instrumental characteristics and for deriving intercalibration factors for XCO2 and XCH4, which take into account residual differences of instrumental characteristics. An excellent level of agreement and stability was found between the different spectrometers: the uncorrected biases in XCO2 and XCH4 are smaller than 0.01 and 0.15 %, respectively, and the drifts are smaller than 0.005 and 0.035 %. As an additional sensitive demonstration of the instrumental performance we show the excellent agreement of ground pressure values obtained from the total column measurements of O2 and barometric records. We find a calibration factor of 0.9700 for the spectroscopic measurements in comparison to the barometric records and a very small scatter between the individual spectrometers (0.02 %). As a final calibration step, using a co-located TCCON (Total Carbon Column Observation Network) spectrometer as a reference, a common scaling factor has been derived for the XCO2 and XCH4 products, which ensures that the records are traceable to the WMO in situ scale.

The Renaissance Attitude Toward Interpretation in Instrumental Performance

The Many

Most of our performances of Renaissance ensemble music mirror only too exactly the blank appearance of the original parts. The normal reaction of the conscientious instrumentalist who has been brought up on scores sprinkled with signs indicating just how each note is to be played—as well as what tone is be to sounded and for how long—is to conclude that, if no ‘expression’ signs are present, then the composer was concerned only with pitch and duration, and that to produce anything more would be to mispresent his intentions. The resulting ‘abstract’ performance is inadvertently encouraged by those musical scholars who stress the new emphasis on expression of emotion found in the Baroque period (always in contrast to the music of earlier periods) and by the many musicologists who look at early instrumental music primarily to search for traces of its liberation from the tyranny of vocal style.

The Way

Over the past few years, instrumental performance has been subject to considerable research in this journal and elsewhere. A great deal of this research has concentrated on the practice strategies and individual lessons, which most students undertake in preparing as performers. Little has been done on raising standards of performance on a larger scale within the context of a large music department. This article describes the outcomes of a two-year programme undertaken with undergraduates at Barnsley College. It looks specifically at the scope for curriculum changes over that period and the way the various individual aspects of performance lessons are brought together through a weekly class which focuses on the demands of a public performance and the strategies required to prepare for that event.

Operant Training

Human experiments have demonstrated that instrumental performance of an action and the causal beliefs of the effectiveness of an action in producing a reward are correlated and controlled by the probability of an action leading to a reward. The animal literature, however, shows that instrumental performance under free-operant training differs even when these reward probabilities are matched while subjects undergo training under ratio or interval schedules of reward. In two experiments, we investigated whether causal beliefs would correlate with instrumental performance under interval and ratio schedules for matched reward probabilities. In both experiments we found that performance was higher under ratio than under interval training. However, causal beliefs were similar between these two conditions despite these differences in instrumental performance. When reward probabilities were increased by experimental manipulations in Experiment 2, the causal beliefs increased but performance decreased with respect to Experiment 1. This is evidence that instrumental performance and causal action-reward attribution may not follow from the same psychological process under free-operant training.
