Vocabulary acquisition is a fundamental component of foreign language learning, as it directly influences learners’ ability to communicate effectively. In recent years, educators have increasingly incorporated music and songs into English language instruction to enhance vocabulary development. Music provides an enjoyable and motivating learning environment, while songs offer authentic linguistic input that facilitates memorization, pronunciation, and contextual understanding of new lexical items. This article examines the pedagogical role of music and songs in teaching English vocabulary, discusses their cognitive and affective benefits, and explores practical strategies for integrating musical materials into language classrooms. The findings suggest that music-based instruction can significantly improve vocabulary retention, learner engagement, and overall language proficiency.
