Music moves us, literally. We tend to move the body in synchrony with the beat. Individuals without any professional music training are capable of singing or humming along with an unfamiliar melody or indicating the melodic contour by means of hand gestures. Musicians who play by ear are able to do the same on an instrument.In this study an attempt was made to quantify the extent to which professional keyboard performers were able to play by ear, and whether improvising musicians were superior to non-improvising. During the experiment, subjects were asked to listen to short, unfamiliar music excerpts recorded on a MIDI controller. Subjects were asked either to play along, replicate the excerpt, transpose it to a different key, or to harmonize it. Subjects were recruited from two groups of classically-trained musicians: improvising and non-improvising pianists and church organists. The bass and treble parts extracted from each MIDI sequence were compared with the bass and treble from the aural model, yielding an alignment score for each task. The comparison was performed using content-based music retrieval software developed in the WITCHCRAFT project for the study of folksong melodies. Results showed that the top voice was replicated better than the bass. There were large differences between the musicians. As a group, improvising musicians scored better than non-improvising musicians, however this difference was not significant. Mixture analysis showed that top-scorers came from both groups. Subjects with perfect pitch did not perform better.
This ‘Big Ideas’ paper will explore the relevance of the constraintsled approach (Davids et al., 2008) for nurse education, specifically when teaching nursing skills. The constraints-led approach is an applied theory, based on the ecological-dynamics framework, which explains that skill learning is a process of adjusting to the characteristics of a situation, instead of reproducing isolated, “ideal” movements out of context (Araújo et al., 2017; Seifert et al., 2017, 2019). During nurse education however, students often find themselves in isolated practice drills in which they practice a nursing skill based upon detailed protocols and/or explicit instructions by the lecturer. Following the ecological dynamics framework (Button et al., 2021), we argue that there is no single ideal way of executing a certain task. In clinical practice, there are often more than one appropriate task executions for a certain situation, and on the other hand, a certain task execution might be effective in one situation, but less effective in another. As all patients and contexts contain unique characteristics, students need to practice with representative characteristics from clinical practice, so that they learn attuning to contextual information, instead of simply following step-by-step instructions (Fajen et al., 2009; Pinder et al., 2011; Wulf and Lewthwaite, 2016).
