Sustainable development within music education is essential, particularly in ensuring that popular music can continually and effectively serve educational systems. This research aims to 1) examine pop music chord progression, 2) develop a chord progression book specifically for teaching music students, and 3) evaluate the effectiveness of this educational tool in improving music composition skills. A mixed-methods approach, incorporating both qualitative and quantitative research, was used. Research tools included an interview guide, Ioc forms, a textbook, and a performance assessment form. Interviews were conducted with five experts in pop music composition, while a group of 14 undergraduate music students participated in the experimental study. These methods evaluated how teaching popular music chord composition enhances students’ practical composition abilities. The findings indicate that 1) chord composition in popular music primarily involves five aspects: melody, rhythm, chord structure, music form, and melody development techniques, with melody and chord as the foundational elements; 2) the chord progression textbook for popular music differs from traditional composition theory texts, combining theory and practical application with a focus on chord progression techniques; and 3) instruction in popular music chord composition significantly enhances students’ skills in melody creation, production, and listening, ultimately fostering practical music creation abilities. This study supports the sustainable integration of popular music in both music infrastructure construction and music education system development, offering insights into how such integration can drive long-term advancements in music education.

The article focuses on conceptual factors that contribute to the formation of the school as an exemplary educational institution. The questions about effective administration and leadership are answered by analyzing the findings and insights of educational theorists. What are the moral criteria of leadership and the ambiguous and complex decision-making process? How the insights from important work design theories correlate with important conceptual approaches to school management. An important emphasis is placed on diversity and the concept of the school microcosm: how effective administration can increase the self-efficacy of teachers, which in turn always positively affects the academic performance of students. The scientific novelty of the article discusses the views of heads of public schools in Georgia, their subjective experiences, and recommendations, together with the theoretical and conceptual tools of school management. Through the phenomenological analysis conducted with school leaders in Georgia, we will get to know the professional skills and strategies that lead to the strengthening of the school’s pulse and focusing on the so-called “school of the future” model.
