Music training is associated with enhanced executive function but little is known about the extent to which harmonic aspects of musical training are associated with components of executive function. In the current study, an array of cognitive tests associated with one or more components of executive function, was administered to young adult musicians and non-musicians. To investigate how harmonic aspects of musical training relate to executive function, a test of the ability to compose a four-part harmony was developed and administered (...) to musicians. We tested the working hypothesis that musicians would outperform non-musicians on measures of executive function, and that among musicians, the ability to harmonize would correlate positively with measures of executive function. Results indicate that musicians outperformed non-musicians on the Tower of London task, a measure of planning and problem-solving. Group differences were not detected on tasks more selective for inhibitory control, conflict resolution, or working memory. Among musicians, scores on the harmony assessment were positively correlated with performance of the Tower of London task. Taken together, the current results support a strong relationship between musicianship and planning and problem solving abilities, and indicate that the ability to harmonize is associated with components of executive function contributing to planning and problem solving.

Management and performance are interdisciplinary, spanning diverse fields such as business, industry, government, sports, arts, health and education. In four studies, world-class performers in a variety of fields, for example, management, sports and classical music, have been found to display higher mind–brain development than matched average-performing control groups, including more frequent peak experiences. In this article, we will use a selection of clearly articulated peak experiences reported by these world-class performers to illustrate the subjective or inner nature of optimal performance. (...) Such performance seems to be characterized by inner calmness and happiness amidst dynamic activity, maximum wakefulness, effortlessness and ease of functioning, and a sense of perfection. In order to provide an adequate theoretical framework for understanding peak experiences, we combine Western developmental psychology with the advanced growth range of higher consciousness, as outlined in the ancient Vedic knowledge of India.
