James Joyce’s poetry collection, Chamber Music, which he defines as “chambermade music,” epitomizes his literary pursuit of musicality and resonates with his dual identity as both a lyric poet and an Irishman. Musicality in Chamber Music can first be seen in allusions to musical elements which contribute to the musical revelation of emotions. Furthermore, repetition pervades Chamber Music both in themes and structure, resonating with the cyclical nature of Irish music. Under the influence of the Irish Revival, Joyce creatively navigates the realm of musical lyrics, draws a balance between English and Irish traditions, and provides a seminal model for his further exploration of musical writing in his later masterpieces. 展开更多

From the perspective of linguistic musicology,this paper discusses the musical features of Yulinling:Farewell in Autumn,a representative work of Yong Liu,a famous lyricist of the Song Dynasty.Through a systematic analysis of the core elements of the poem,such as rhyme,timbre,key,and rhythm,it reveals the intrinsic connection between poetry and music and proposes a new way of thinking about the modern interpretation of ancient poetic songs.This paper not only enriches the understanding of Yong Liu’s works but also provides new theoretical support for modern music education of classical poetry.In addition,this paper explores the practical application value of poetic musicality analysis in cultural inheritance and modern adaptation of classical poems,providing new insights into the contemporary inheritance of cultural heritage. 展开更多

The purpose of this article is to contextualize the world’s oldest art song directly associated with the railway-Travelling Song by the Russian composer Mikhail Glinka(1804-1857).The composer’s personal circumstances surrounding the creation of the song are examined,along with the historical and technical background of that era.While railways have always been associated with technological progress,new solutions for high-power engines,and the accuracy of arrival and departure timetables,the poetic and romantic side of train travel and railways in general has not yet received sufficient academic coverage.This essay is intended to partially fill this gap,though it rather outlines directions for possible development of its topical range.Each of the suggested reference points and stories is in itself an example of how the arts reflected the inspiration that cutting-edge technological advances of the period were exerting on artists,musicians,and other creative individuals. 展开更多

Background:Music has proven to be vital in enhancing resilience and promotingwell-being.Previously,the impact of music in sports environments was solely investigated,while this paper applies it to study environments,standing out as pioneering research.The study consists of a systematic development of a conceptual framework based on theories of Uses and Gratification Expectancy(UGE)and perceived motivation based on music elements.Their components are observed variables influencing students’psychological well-being(as the dependent variable).Resilience is examined as a mediator,influencing the relationships of both observed and dependent variables.The main purpose of this study is to highlight the positive effects of online music consumption on the psychological well-being of students.Methods:Semi-structured qualitative interviews were conducted with eighteen final year creative multimedia undergraduate students belonging to five central region Malaysian universities,especially on their UGE needs,and a similar concept survey instrument with two hundred participants.The interview data were analysed through thematic analysis,while the survey data through descriptive and Partial Least Squares Structural Equation Modeling(PLS-SEM).Results:The results highlight that students gain motivation from online music,which positively affects their psychological well-being(β=0.190,p=0.003,f^(2)=0.037),while resilience significantly affects this relationship(β=0.562,p<0.001,f^(2)=0.461).However,the results also predict a partial relationship between constructs based on UGE with psychological well-being,mediated by resilience,i.e.,AT-UGE(β=0.021,p=0.783,f^(2)=0.000),SIPI-UGE(β=0.228,p=0.004,f^(2)=0.044).Conclusion:The outcome of the study reflected practical,meaningful,and statistically significant results.The majority of the predictors,with the exception of one,i.e.,AT-UGE,displayed a clear positive relation of online music consumption on the Psychological Well-being of students.Future research will explore varying contextual factors impacting online music-related gratifications,motivations,and resilience,along with additional potential mediators and moderators. 展开更多
