Brain-based: The Earworms method not only provides the words, phrases and grammar that you need for language learning, it also actively anchors them into the auditory cortex of your brain! It’s much more than language courses, it's language learning! Learn French, Spanish, English, Italian, German or Dutch listening to music lyrics. 2. Music is the key: Using music as the medium to learn languages is not only fun, it is also effective. Firstly, music puts the learner into the optimum state of consciousness for learning different languages. Secondly, music lyrics learning allows repetition (a prerequisite for language learning). On top of that, music engages and stimulates both hemispheres of the brain, unleashing more learning potential. 3. Chunking: Instead of language learning in terms of individual words and grammar, the Earworms approach immerses the learner in real-life dialogues and expressions with lyrics. These are broken down into bite-size chunks, practiced rhythmically with music and then reconstructed into full sentences. This gives the learner a strong sense of how real language courses are constructed and learning French, Spanish, German, Italian, English and other different languages and their vocabulary becomes easy. IMPORTANT FEATURES * Developed by language teaching experts. * Convenient. 6-9 minute tracks.
