Recently I visited the website Incomepete and searched through the royality free music section and choose a song that could be used in the classroom. I choose to download Feelin Good. It has an up-beat tempo that is uplifting and feel good. By adding this to a website or to a class it would attract students attentions and make their research more up lifting and less boring, however it's not so over powering that the students will lose their concentration.
Say the students came from a history lesson that required them to read and take notes from a text book, to a sport lesson requiring energy. The sport teacher could play this song at the beginning of the lesson to get the students in an energetic mood. It could also be used in the sense of ciriculum. For example students could include music in thier oral presesntations, powerpoint presesntations and/or as a basis for a written assignment that relates to human bahaviour and music. These are just a few ideas of how music can be used in a classroom or on the net.
