Theoretical Rationale
A large amount of literature which discusses the value of using songs in ESL/EFL classrooms is not empirically based. However, based upon teacher experience, the first hand knowledge of what actually occurs in a language classroom is, in fact, very valuable. The first step in developing a theoretical rationale for using songs in the classroom is to label the types of listening processes and then identify the reasons teachers and researchers provide. From here, we can see that the teachers' motives are actually grounded in theory. Patterns emerge from the literature as to why teachers and researchers find using songs valuable. These patterns include affective reasons, cognitive reasons, and linguistic reasons.
There are two processes involved in listening, and both can be utilized when songs are used in the classroom. The activity which is selected for a particular song will determine which of these processes is active. Cullen (1999) states that
The first is bottom-up processing where the listener builds up the sounds into words, sentences and meaning. The second is top-down processing where the listener uses background knowledge to understand the meaning of a message. Practicing both of these processes is essential for developing listening comprehension.
The affective, cognitive, and linguistic reasons for using songs which follow, are all grounded in learning theory, and provide insights into the benefits of songs in the classroom.
