This study compares early childhood music education curricula in Thailand, Germany and the United States with particular focus on curriculum frameworks, pedagogy and assessment. Thai Early Childhood Education Curriculum 2025, developed by Ministry of Education (OBEC) is the national core curriculum that is applied nationwide. It is aimed at supporting the development of the whole child with the integration of music and movement in developmental goals that encompass emotional, mental, social, cognitive, and creative aspects of development. Musical content is expressed through such elements as rhythm, melody, Characteristics of sound, texture, and form, while music skills include listening, singing, moving, playing, and creation.The German Joint Framework of the Federal States for Early Childhood Education (2004; revised in 2021-2022 by JFMK and KMK) is a national reference framework which places particular emphasis on the aesthetic and multisensory education and takes a child-centred approach to a holistic and equal development. Music and movement are integrated into the aesthetic learning experiences that foster perception, creativity, and cultural identity. Its musical content is very similar to Thai musical content, with the only addition being tone color.In contrast, the U.S. National Core Arts Standards-Music (2014), generated by the National Association for Music Education (NAfME) and the National Coalition for Core Arts Standards (NCCAS), provides clear music learning standards for pre-K and Kindergarten. Based on four artistic processes - Creating, Performing, Responding, and Connecting, the framework is designed to develop musical knowledge, creativity and critical thinking. Regarding musical content, the U.S. curriculum covers a broader range of musical elements, including harmony and tone color, and additionally incorporates music reading skills. The assessment method differs: in Thailand and Germany, it relies on teacher observation, whereas in the U.S., evaluation is conducted through self-, peer-, and teacher feedback.The comparison demonstrates a common philosophy between the three countries, which is that music and movement should be used to facilitate holistic child development involving emotional, social, and intellectual development. Nevertheless, there are key structural and philosophical differences: while Thailand and Germany have a greater focus on integrated, experience-based learning, with a qualitative assessment process based on observation; the United States has a standards-based approach that is more specific to measurable skill outcomes and criteria-based evaluation. These differences relate to the philosophy of education in each country and to the different cultural values expressed in music education.
