This position paper aims to raise awareness among educational policymakers, teacher educators, and school leaders around the world about the urgent need to better prepare Early Childhood Education (ECE) teachers in music education. Most countries fail to sufficiently train teachers to meet the music-related expectations of contemporary ECE curricula, which inevitably affects young children's learning and development. Our first goal is to describe this worrisome reality in depth, based on prior literature. We elaborate on the limited music education (extracurricular, pre-service, and in-service) typically offered to ECE teachers worldwide. We then highlight the negative consequences that result from having a teaching force clearly ill-prepared in this area. Based on studies conducted with pre-service and/or in-service ECE teachers, we summarize what is known about teachers' learning needs, motivations, and preferences regarding music education. Our second goal is to propose a series of low-cost, sustainable, and easily scalable strategies to strengthen teachers' preparation. Practical and policy-related potential obstacles are discussed. As final remarks, we urge ECE stakeholders to (a) investigate the specific needs, motivations, and preferences of their local teachers in music education, (b) design and implement responsive training strategies, and (c) examine their impact on teachers and/or children.
