Abstract A central problem in all language teaching is to teach the correct use of prepositions. There are grammar rules, but also a lot of exceptions and idiomatic expressions that often have to be learnt by examples or by heart. A trick for learning might be to use a mnemonic method with songs and music to memorize a correct use of prepositions. The purpose of this study is to test a language teaching didactic exercise for knowledge of preposition in Spanish with songs and music. Grammatical aspects, rules and exceptions when studying prepositions in Spanish are presented. A literature review shows the significance of music for language learning. By lesson trials the five so called “empty” prepositions in Spanish: a, con, de, en and por, are studied by 40 high school students only by listening to and singing two different songs in the beginning and at the end of each Spanish lesson during two weeks. The result of the study shows an improved knowledge of correct use of the 5 Spanish prepositions among the students using the method. Furthermore, the language teaching didactic exercise with song and music was seen as a pleasurable learning experience by the students.
