Melodic Accent as an Emergent Property of Tonal Motion

In a previous continuation tapping study (Ammirante, Thompson, & Russo, in press), each tap triggered a discrete tone in a sequence randomly varying in pitch height and contour. Although participants were instructed to ignore the tones, pitch distance and pitch contour influenced intertap interval (ITI) and tap velocity (TV). The current study replicated these findings with original melodies. Results were interpreted as an effect of apparent tonal motion, with deviation in ITI and TV mirroring implied tonal acceleration. Due to overlapping perceptual and motor representations, participants may have failed to disambiguate acceleration implied by tonal motion from the acceleration of their finger trajectory. Dissociative effects of pitch distance on ITI and pitch contour on TV implied that pitch distance influences the initial finger extension while pitch contour influences later finger flexion. Acceleration in ITI and TV were also both correlated with melodic accent strength values from perceptual data (Thomassen, 1982), suggesting that perception and production of melodic accent emerge from shared action associations

Investigating the Role of the Primary Motor Cortex in Musical Creativity: A Transcranial Direct Current Stimulation Study

Neuroscientific research has revealed interconnected brain networks implicated in musical creativity, such as the executive control network, the default mode network, and premotor cortices. The present study employed brain stimulation to evaluate the role of the primary motor cortex (M1) in creative and technically fluent jazz piano improvisations. We implemented transcranial direct current stimulation (tDCS) to alter the neural activation patterns of the left hemispheric M1 whilst pianists performed improvisations with their right hand. Two groups of expert jazz pianists (n = 8 per group) performed five improvisations in each of two blocks. In Block 1, they improvised in the absence of brain stimulation. In Block 2, one group received inhibitory tDCS and the second group received excitatory tDCS while performing five new improvisations. Three independent expert-musicians judged the 160 performances on creativity and technical fluency using a 10-point Likert scale. As the M1 is involved in the acquisition and consolidation of motor skills and the control of hand orientation and velocity, we predicted that excitatory tDCS would increase the quality of improvisations relative to inhibitory tDCS. Indeed, improvisations under conditions of excitatory tDCS were rated as significantly more creative than those under conditions of inhibitory tDCS. A music analysis indicated that excitatory tDCS elicited improvisations with greater pitch range and number/variety of notes. Ratings of technical fluency did not differ significantly between tDCS groups. We discuss plausible mechanisms by which the M1 region contributes to musical creativity

Music, Pleasure, and Meaning: The Hedonic and Eudaimonic Motivations for Music (HEMM) Scale

Many people listen to music that conveys challenging emotions such as sadness and anger, despite the commonly assumed purpose of media being to elicit pleasure. We propose that eudaimonic motivation, the desire to engage with aesthetic experiences to be challenged and facilitate meaningful experiences, can explain why people listen to music containing such emotions. However, it is unknown whether music containing violent themes can facilitate such meaningful experiences. In this investigation, three studies were conducted to determine the implications of eudaimonic and hedonic (pleasure-seeking) motivations for fans of music with violent themes. In Study 1, we developed and tested a new scale and showed that fans exhibit high levels of both types of motivation. Study 2 further validated the new scale and provided evidence that the two types of motivations are associated with different affective outcomes. Study 3 revealed that fans of violently themed music exhibited higher levels of eudaimonic motivation and lower levels of hedonic motivation than fans of non-violently themed music. Taken together, the findings support the notion that fans of music with violent themes are driven to engage with this music to be challenged and to pursue meaning, as well as to experience pleasure. Implications for fans’ well-being and future applications of the new measure are discussed.</p

How Chanting Relates to Cognitive Function, Altered States and Quality of Life

Chanting is practiced in many religious and secular traditions and involves rhythmic vocalization or mental repetition of a sound or phrase. This study examined how chanting relates to cognitive function, altered states, and quality of life across a wide range of traditions. A global survey was used to assess experiences during chanting including flow states, mystical experiences, mindfulness, and mind wandering. Further, attributes of chanting were assessed to determine their association with altered states and cognitive benefits, and whether psychological correlates of chanting are associated with quality of life. Responses were analyzed from 456 English speaking participants who regularly chant across 32 countries and various chanting traditions. Results revealed that different aspects of chanting were associated with distinctive experiential outcomes. Stronger intentionality (devotion, intention, sound) and higher chanting engagement (experience, practice duration, regularity) were associated with altered states and cognitive benefits. Participants whose main practice was call and response chanting reported higher scores of mystical experiences. Participants whose main practice was repetitive prayer reported lower mind wandering. Lastly, intentionality and engagement were associated with quality of life indirectly through altered states and cognitive benefits. This research sheds new light on the phenomenology and psychological consequences of chanting across a range of practices and traditions

The effects of cultural source sensitivity on music appreciation

Music appreciation is a complex process that involves responses to surface-level structure, personal associations, and source sensitivity. Source sensitivity is an understanding of the context in which a musical artifact was created. This article joins a growing body of literature in which program notes are manipulated to highlight the importance of source sensitivity, shifting the focus onto cultural context. Two hundred eighty-four participants formed six groups in a 2×3 between-subjects design. Western and non-Western participants (ethnicity condition) listened to an original percussion composition accompanied by a short text providing a Western, Indian, or blended cultural context (cultural context condition). They then evaluated the music across a range of measures. Exploratory factor analysis revealed two factors of appreciation: Hedonic and Eudaimonic. Results revealed significant ethnicity–cultural context interactions for both. In the Indian context, Western participants exhibited high appreciation, whereas non-Western listeners exhibited low appreciation. Among non-Westerners, appreciation was highest in the blended context. Our results demonstrate an association between cultural source information and music appreciation. We propose that Western participants experience a proteophilic response to Indian music due to their secure status as members of a dominant social group. Non-Western participants, however, require a neutralizing Western context to similarly appreciate Indian music content.</p
