This curriculum project aims to recognize the importance of teaching students music with ear-training. The goal is to identify the strengths and weaknesses of ear-training methods. This paper will review existing ear-training methods research. The literature will be reviewed regarding the biology of how listeners hear music, how geographic location influences elements of sound, how emotion influences communication, and why people like the music they like. The second chapter of this article discusses how singing on solfège creates stronger musicianship in all musicians as ear-training is essential for teaching music. Ear-training helps students recognize sounds and sonic events they have heard since they were in their mother’s womb. Ear-training also provides a foundation for teaching music.
