Three Musical Warm-ups

Using 'realia' in the classroom - examples of the language or culture produced for real situations rather than specifically for students - is always a great way to encourage our students to engage with their language of study outside the classroom. Music can be particularly useful - once students are introduced to a singer, group, or musical style that they like, they'll often spend hours on YouTube listening, which is a pretty fun way to study a new language. So, in the name of promoting student engagement with the target language outside of the classroom, I give you three examples of warm-up activities that use songs:

Fill-in-the-Blank Lyric Sheets
First, find a song that uses some of the vocabulary that students are studying, or that repeats an example of a new grammatical point. For example, I use ¿Dónde Estás Corazón? by Shakira when reviewing question words and the verb estar with my students.Next make worksheets with the lyrics - but with some of the words missing.You can usually find the lyrics of popular songs online to avoid having to transcribe them all as you listen. During the first few minutes of class, students listen to the song once or twice, trying to fill-in the missing words. When finished, students take turns reading the completed lyrics. Finally, students summarize the 'main idea' of the song - in the target language, of course.

Song Lyric Scramble
Choose a song in which the refrain is repeated several times. Give students strips of paper, each with one line of the refrain printed on it. Students then listen to the song, and try to put the lines of the refrain in their proper order. More advanced classes can put an entire song in its proper order.

American Idol
Give students a short song to memorize, or have them memorize the refrain of a longer song. Students must then either sing or recite the song for the class, and will be rated by their classmates on their accuracy, pronunciation, fluency - and style.

Of course, having the students summarize the main idea of the song in simple prose (in the target language) is a great way to get them talking after listening to any song, and they always want to give their opinions about if they liked the song or not.
