This article examines how classical music students understand early twentieth-century recordings in higher music education. A qualitative research method was chosen to investigate the beliefs and self-reported practices of 16 students enrolled in a European conservatoire, whose attitudes were considered through the administration of a semi-structured questionnaire and an interview. Their responses identified seven main themes: (1) beliefs, (2) sources, (3) self-reported practices, (4) repertoires/performers, (5) educational implications, (6) limits and (7) benefits.
Results show how much students value early twentieth-century recordings – especially when it comes to analysing the performance practices of the past and developing new interpretations – and how articulate their responses can be with regard to specific stylistic and technical issues. However, possibly due to informal learning strategies and the lack of curricular teaching activities focusing on listening to and analysing recorded interpretations, some responses highlighted a misrepresentation of our recent musical past and the need for a more structured curricular activity. This last should benefit from a vast body of scholarly literature whose relevance is still underestimated among music practitioners.

Recent research has explored gender ratios in orchestras but not specifically in brass playing, a historically masculine field. Three studies investigated gender ratios in a variety of brass-playing situations. Public domain and questionnaire data were analysed using descriptive statistics, and a chi-square test found a significant effect of instrument size on gender ratios. The highest percentage of female brass players was found in youth ensembles, followed by the freelance workforce, semi-professional brass bands and then professional orchestras, indicating a leaky pipeline effect. These results show that women are still under-represented in most brass-playing contexts, particularly the most prestigious positions, and that more can be done in music education to change this.

This article explores the multifaceted landscape of music literacy education in South African secondary schools through an anagrammatic lens. Music literacy education is symbolised by the anagrams ‘NAOUIEDCT’ and ‘RCSSEOEUR’, encapsulating resource-related, cultural and pedagogical complexities. This comparison of music literacy education to anagrams creates an interesting analogy that can shed light on the complexity and challenges inherent in the situation. It aims to unravel these complexities, like solving a multifaceted puzzle. Thus, the result of this qualitative interpretive research project is the transformation of a complex challenge (conundrum) into symbolic puzzles (anagrams), aiming to decipher the intricacies of music literacy education. This methodology offers an approach to foster engagement and collaborative work toward future solutions. Through a comprehensive exploration, this research aims to unravel the layers of challenges inherent in Music Education, offering insights and recommendations for a nuanced and enriched educational experience. The data for this research project were collected through semi-structured interviews and, consequently, a thematic content analysis was carried out, first in a descriptive level of analysis, followed by a conceptual level of analysis. Computer-aided qualitative analysis software, namely ATLAS.tiTM23, played a valuable and significant role in both the literature review and thematic content analysis phases of this study.

In the 21st century, we are increasingly exposed to music created entirely on computers. This article shows how pioneering music teachers approach the challenge of teaching music on the laptop computer in the context of one-to-one musical instrument lessons. Interviews and observations with five laptop teachers in Norwegian secondary schools enabled the authors to explore characteristic challenges in this field. This study explored two research questions: What are the instructional strategies, content and ‘repertoire’ in music lessons on laptop computer? How have teachers experienced the laptop’s evolutionary process towards legitimation?

Music teachers in secondary education tend to undervalue the professional competence of creating music, in response to educational models that prioritise the development of musical interpretation skills. The aim of this research is to identify the factors that contribute to this belief among teachers in Spain, by analysing the results of the Professional Competences of the Music Teacher questionnaire (n = 112). Significant differences were found between age categories, as well as significant linear correlations between teachers’ perceptions of their preparation during initial training, their practical skills and habits, and the professional importance they attached to their competence in musical creation.

This article explores the potential barriers for emerging composers to constructing and maintaining a career in the field of composition in Scotland, viewed through the lens of both those early in their careers and the experience of others who have worked professionally for many years. Thirty-nine composers responded to a survey that highlighted the role of educational mentoring, the need for monetary stability and the challenges faced by female and older emerging composers. The professional lives of current Scottish composers have been seldom studied, and the purpose of this investigation is to explore, inform and provide suggestions for future consideration.

This Participatory Action Research (PAR) investigates the integration of informal music learning in Macau’s educational context, guided by the Model of Generative Change (Ball, 2009). Engaging the participating college students (N = 41), this study explores how learners perceive the formal–informal learning continuum (Folkestad, 2006) through the four stages of informal learning experiences: awakening, agency, advocacy and efficacy (Ball, 2009). Through multiple data collection methods and qualitative analysis, students experienced (a) autonomous learning, (b) joyful peer learning, (c) creative exploration and skill development and (d) resilience through challenges. Moreover, the study highlights the stages of awakening, introspection and critique from the students’ perspectives. Notably, a subset of students, predominantly those with prior formal instrumental training, expressed critiques concerning informal learning, predominantly regarding its perceived lack of systematic structure and foundational skills. These insights suggest a need to further embed informal music learning in Macau to foster a dynamic change towards generativity and a ‘multileveled cultural world’ (Law & Ho, 2015). The implications point to a broader pedagogical shift that values diverse learning experiences, which may enhance the development of a more adaptable, innovative and well-rounded musical skill set within the student population in Macau.

When young people leave the musical world of their school environment, a lack of clear routes into adult musical engagement brings a risk of wasted ability, motivation and enjoyment, which arguably undermines the value of music education. This study explored the factors that influence continued musical participation among young British adults who had been actively engaged in school music. Musical participation is defined in this research as group music-making in either a formal or informal setting. Participants (n = 102) completed an online questionnaire or were interviewed (n = 6) about their past and present musical experiences along with future expectations for music-making. The stark headline finding was that while 87% of participants had intended to continue with music-making beyond school, only 48% had found groups to join. Nonetheless, 78% expected to continue with music-making in the future. Our research therefore suggests that any break from musical participation need not be permanent for individuals who have established strong musical identities through their early experiences. To conclude, we present a model of lifelong musical participation that illustrates the influences, motivations and choices that contribute to sustained musical engagement.

COVID-19 presented many challenges while the shift to online learning also provided unexpected opportunities for music teachers. During the pandemic, two researchers who are teacher educators undertook a composing project with music teacher education students in Scotland and Australia in response to the theme: My Life in Isolation: A World Apart or Same Difference? Turino’s (2008) theory of participatory music making will be drawn upon to analyse this collaborative online music and video creation project. What participation means as a music-maker will be discussed. The paper argues for greater attention to the affordances of digital collaborative music technology tools to build the confidence of pre-service teachers to facilitate real-world composing projects to promote participation, collaboration and social interaction.

The need for effective continuing professional development (CPD) in music education is outlined and literature on CPD for generalist teachers and teaching assistants is reviewed. A small qualitative study is then presented that took advantage of a music-making project led by folk musicians in six special schools in England. This study focused on the generalist teaching staff who actively supported their pupils to participate. The staff reported that their own confidence in working musically had increased, as had their awareness of the importance of music for children. It is suggested that these outcomes were achieved through incidental CPD, potentially paving the way for further, deliberate CPD.
