Processes and experiences of creative cognition in seven Western classical composers
In a qualitative study, we explored the range of reflections and experiences involved in the composition of score-based music by administering a 15-item, open-ended, questionnaire to seven professional composers from Europe and North America. Adopting a grounded theory approach, we organized six different codes emerging from our data into two higher-order categories ( the act of composing and establishing relationships). Our content analysis, inspired by the theoretical resources of 4E cognitive science, points to three overlapping characteristics of creative cognition in music composition: it is largely exploratory, it is grounded in bodily experience, and it emerges from the recursive dialogue of agents and their environment. More generally, such preliminary findings suggest that musical creativity may be advantageously understood as a process of constant adaptation â one in which composers enact their musical styles and identities by exploring novel interactivities hidden in their contingent and historical milieux
Evaluation of Rich and Explicit Feedback for Exploratory Search
A userâs goals and interests during an exploratory search task are often ambiguous and complex. When engaging with new documents, people regularly use annotations to help better understand them and make them their own. These annotations can also pro- vide rich information to gain insight into a readerâs interests. In particular, it is possible to use highlights as a richer form of feed- back compared to traditional document-level relevance feedback. We first show that this form of feedback leads to improvements in document retrieval in exploratory search tasks with simulated users when compared to relevance feedback. We then present an evaluation platform which will allow us to understand the retrieval performance, user experience, and behavioral characteristics of human subjects using highlights as feedback. Finally, we propose an experimental design with human subjects. We hope that our experimental findings will help improve current simulated user evaluations for such systems
Artificially Synthesising Data for Audio Classification and Segmentation to Improve Speech and Music Detection in Radio Broadcast
No embargo required.Segmenting audio into homogeneous sections such as music and speech helps us understand the content of audio. It is useful as a pre-processing step to index, store, and modify audio recordings, radio broadcasts and TV programmes. Deep learning models for segmentation are generally trained on copyrighted material, which cannot be shared. Annotating these datasets is time-consuming and expensive and therefore, it significantly slows down research progress. In this study, we present a novel procedure that artificially synthesises data that resembles radio signals. We replicate the workflow of a radio DJ in mixing audio and investigate parameters like fade curves and audio ducking. We trained a Convolutional Recurrent Neural Network (CRNN) on this synthesised data and outperformed state-of-the-art algorithms for music-speech detection. This paper demonstrates the data synthesis procedure as a highly effective technique to generate large training sets for deep neural networks
The effect of improvisational music therapy on the treatment of depression: protocol for a randomised controlled trial
Background.
Music therapy is frequently offered to individuals suffering from depression. Despite the lack of research into the effects of music therapy on this population, anecdotal evidence suggests that the results are rather promising. The aim of this study is to examine whether improvisational, psychodynamically orientated music therapy in an individual setting helps reduce symptoms of depression and improve other health-related outcomes. In particular, attention will be given to mediator agents, such as musical expression and interaction in the sessions, as well as to the explanatory potential of EEG recordings in investigating emotion related music perception of individuals with depression.
Methods.
85 adults (18–50 years of age) with depression (ICD-10: F 32 or F33) will be randomly assigned to an experimental or a control condition. All participants will receive standard care, but the experimental group will be offered biweekly sessions of improvisational music therapy over a period of 3 months. A blind assessor will measure outcomes before testing, after 3 months, and after 6 months.
Discussion.
This study aims to fill a gap in knowledge as to whether active (improvisational) music therapy applied to people with depression improves their condition. For the first time in this context, the mediating processes, such as changes in musical expression and interaction during the course of therapy, will be objectively investigated, and it is expected that the results will provide new insights into these processes. Furthermore, the findings are expected to reveal whether music related emotional experiences, as measured by EEG, can be utilized in assessing a depressive client's improvement in the therapy. The size and the comprehensiveness of the study are sufficient for generalizing its findings to clinical practice as well as to further music therapy research.

Listening to music reduces eye movements
Listening to music can change the way that people visually experience the environment, probably as a result of an inwardly directed shift of attention. We investigated whether this attentional shift can be demonstrated by reduced eye movement activity, and if so, whether that reduction depends on absorption. Participants listened to their preferred music, to unknown neutral music, or to no music while viewing a visual stimulus (a picture or a film clip). Preference and absorption were significantly higher for the preferred music than for the unknown music. Participants exhibited longer fixations, fewer saccades, and more blinks when they listened to music than when they sat in silence. However, no differences emerged between the preferred music condition and the neutral music condition. Thus, music significantly reduces eye movement activity, but an attentional shift from the outer to the inner world (i.e., to the emotions and memories evoked by the music) emerged as only one potential explanation. Other explanations, such as a shift of attention from visual to auditory input, are discussed
Music therapy for people with substance use disorders
Background-
Substance use disorder (SUD) is the continued use of one or more psychoactive substances, including alcohol, despite negative effects on health, functioning, and social relations. Problematic drug use has increased by 10% globally since 2013, and harmful use of alcohol is associated with 5.3% of all deaths. Direct effects of music therapy (MT) on problematic substance use are not known, but it may be helpful in alleviating associated psychological symptoms and decreasing substance craving.
Objectives-
To compare the effect of music therapy (MT) in addition to standard care versus standard care alone, or to standard care plus an active control intervention, on psychological symptoms, substance craving, motivation for treatment, and motivation to stay clean/sober.
Search methods-
We searched the following databases (from inception to 1 February 2021): the Cochrane Drugs and Alcohol Specialised Register; CENTRAL; MEDLINE (PubMed); eight other databases, and two trials registries. We handsearched reference lists of all retrieved studies and relevant systematic reviews.
Selection criteria-
We included randomised controlled trials comparing MT plus standard care to standard care alone, or MT plus standard care to active intervention plus standard care for people with SUD.
Data collection and analysis-
We used standard Cochrane methodology.
Main results-
We included 21 trials involving 1984 people. We found moderateâcertainty evidence of a medium effect favouring MT plus standard care over standard care alone for substance craving (standardised mean difference (SMD) â0.66, 95% confidence interval (CI) â1.23 to â0.10; 3 studies, 254 participants), with significant subgroup differences indicating greater reduction in craving for MT intervention lasting one to three months; and smallâtoâmedium effect favouring MT for motivation for treatment/change (SMD 0.41, 95% CI 0.21 to 0.61; 5 studies, 408 participants). We found no clear evidence of a beneficial effect on depression (SMD â0.33, 95% CI â0.72 to 0.07; 3 studies, 100 participants), or motivation to stay sober/clean (SMD 0.22, 95% CI â0.02 to 0.47; 3 studies, 269 participants), though effect sizes ranged from large favourable effect to no effect, and we are uncertain about the result. There was no evidence of beneficial effect on anxiety (mean difference (MD) â0.17, 95% CI â4.39 to 4.05; 1 study, 60 participants), though we are uncertain about the result. There was no meaningful effect for retention in treatment for participants receiving MT plus standard care as compared to standard care alone (risk ratio (RR) 0.99, 95% 0.93 to 1.05; 6 studies, 199 participants).
There was a moderate effect on motivation for treatment/change when comparing MT plus standard care to another active intervention plus standard care (SMD 0.46, 95% CI â0.00 to 0.93; 5 studies, 411 participants), and certainty in the result was moderate. We found no clear evidence of an effect of MT on motivation to stay sober/clean when compared to active intervention, though effect sizes ranged from large favourable effect to no effect, and we are uncertain about the result (MD 0.34, 95% CI â0.11 to 0.78; 3 studies, 258 participants). There was no clear evidence of effect on substance craving (SMD â0.04, 95% CI â0.56 to 0.48; 3 studies, 232 participants), depression (MD â1.49, 95% CI â4.98 to 2.00; 1 study, 110 participants), or substance use (RR 1.05, 95% CI 0.85 to 1.29; 1 study, 140 participants) at oneâmonth followâup when comparing MT plus standard care to active intervention plus standard care. There were no data on adverse effects.
Unclear risk of selection bias applied to most studies due to incomplete description of processes of randomisation and allocation concealment. All studies were at unclear risk of detection bias due to lack of blinding of outcome assessors for subjective outcomes (mostly selfâreport). We judged that bias arising from such lack of blinding would not differ between groups. Similarly, it is not possible to blind participants and providers to MT. We consider knowledge of receiving this type of therapy as part of the therapeutic effect itself, and thus all studies were at low risk of performance bias for subjective outcomes.
We downgraded all outcomes one level for imprecision due to optimal information size not being met, and two levels for outcomes with very low sample size.
Authors' conclusions-
Results from this review suggest that MT as 'add on' treatment to standard care can lead to moderate reductions in substance craving and can increase motivation for treatment/change for people with SUDs receiving treatment in detoxification and shortâterm rehabilitation settings. Greater reduction in craving is associated with MT lasting longer than a single session. We have moderateâtoâlow confidence in our findings as the included studies were downgraded in certainty due to imprecision, and most included studies were conducted by the same researcher in the same detoxification unit, which considerably impacts the transferability of findings
