The historically developed practice of learning to play a music instrument from notes instead of by imitation or improvisation makes it possible to contrast two types of skilled musicians characterized not only by dissimilar performance practices, but also disparate methods of audiomotor learning. In a recent fMRI study comparing these two groups of musicians while they either imagined playing along with a recording or covertly assessed the quality of the performance, we observed activation of a right-hemisphere network of posterior superior parietal and dorsal premotor cortices in improvising musicians, indicating more efficient audiomotor transformation. In the present study, we investigated the detailed performance characteristics underlying the ability of both groups of musicians to replicate music on the basis of aural perception alone. Twenty-two classically trained improvising and score-dependent musicians listened to short, unfamiliar two-part excerpts presented with headphones. They played along or replicated the excerpts by ear on a digital piano, either with or without aural feedback. In addition, they were asked to harmonize or transpose some of the excerpts either to a different key or to the relative minor. MIDI recordings of their performances were compared with recordings of the aural model. Concordance was expressed in an audiomotor alignment score computed with the help of music information retrieval algorithms. Significantly higher alignment scores were found when contrasting groups, voices, and tasks. The present study demonstrates the superior ability of improvising musicians to replicate both the pitch and rhythm of aurally perceived music at the keyboard, not only in the original key, but also in other tonalities. Taken together with the enhanced activation of the right dorsal frontoparietal network found in our previous fMRI study, these results underscore the conclusion that the practice of improvising music can be associated with enhanced audiomotor transformation in response to aurally perceived music.

The realization of one’s musical ideas at the keyboard is dependent on the ability to transform sound into movement, a process called audiomotor transformation. Using fMRI, we investigated cerebral activations while classically‐trained improvising and non‐improvising musicians imagined playing along with recordings of familiar and unfamiliar music excerpts. We hypothesized that audiomotor transformation would be associated with the recruitment of dedicated cerebral networks, facilitating aurally‐cued performance. Results indicate that while all classically‐trained musicians engage a left‐hemisphere network involved in motor skill and action recognition, only improvising musicians additionally recruit a right dorsal frontoparietal network dedicated to spatially‐driven motor control. Mobilization of this network, which plays a crucial role in the real‐time transformation of imagined or perceived music into goal‐directed action, may be held responsible not only for the stronger activation of auditory cortex we observed in improvising musicians in response to the aural perception of music, but also for the superior ability to play ‘by ear’ which they demonstrated in a follow‐up study. The results of this study suggest that the practice of improvisation promotes the implicit acquisition of hierarchical music syntax which is then recruited in top‐down manner via the dorsal stream during music performance.
Arts-based environmental education (AEE) denotes an emerging field of pedagogy wherein facilitated art practice intersects with and informs learning about our natural and cultural environments. In it, artmaking is appreciated as a form of coming to knowledge, of making meaning, in its own right, on par with other approaches such as inquiry-based learning in the science classroom. In this article, the author, himself a practitioner, foregrounds two different orientations in learning about nature through art that he considers both as being expressive of AEE. The first one, here called “artful empiricism”, is more established and has its footings in “the Goethean approach”. Participants investigate natural phenomena through direct observation and experience of the world. This is then complemented by intuitive perception. Yet, for the most part, they are absorbed in what Dewey would call a receptive sense of “undergoing”. Aesthetic sensibility is foregrounded, encouraging participants to fine-tune their senses in order to perceive the phenomenon in nature with “fresh eyes”. The second orientation is hardly articulated as an epistemology yet. Here it is called “improvising with emerging properties” and it features an element of working with unforeseen properties that emerge in and through an artmaking process that thematises natural phenomena. It is intrinsically open-ended and an active “acting upon” the world takes centre stage. Through artmaking, participants explore the relationships between themselves and their environs. In his discussion, the author analyses these approaches as two modalities both expressive of a Deweyan cycle of alternating between a receptive undergoing of and active acting upon the world, in different phases of a reflective experience.
