The existence of thematic songs in theme books in Elementary Schools appears to be ineffective in supporting the attainment of learning objectives. In addition to the limited number of songs, the lack of appropriate lyrics and materials remains one of the causes. Due to this, the most possible alternative solution is for teachers to compose their own thematic songs. However, elementary school teachers lack the ability in composing thematic songs, hence they need to be given related training. The purpose of this research is to increase elementary school teachers' capacity for creativity and innovation in order to produce thematic songs. The research employed a participatory action research design, involving 55 teachers from 16 districts and cities in Indonesia. The data were collected using survey, observation, and interview. The results showed that these teachers were able to develop their ability to compose thematic songs. Teachers were also able to utilize technology in the composing process. Based on the aforementioned findings, it can be stated that elementary school teachers can improve themselves and innovate effectively with planned and regulated training.
