As someone who has studied languages to degree level and also taught foreign languages in secondary school, it would be fair to say that I am generally sceptical of DIY langauage teaching CDs - and often with good cause. However, Earworms CDs are an absolutely invaluable learning resource. They will equip you, with minimal effort on your part, with a basic understanding of the language building blocks - which coupled with vocab covering the usual holiday scenarios, such as ordering drinks, food, buying things, counting, etc, will enable you to begin to start to extrapolate from what you have heard on the CD and, with the help of a dictionary, build your own sentences to meet your specific needs. Some grammar is explained - just enough to help with exactly what I've just said above - but not too much to be overwhelming.
I would thoroughly recommend these CDs to anyone who wants just 'holiday' language, or to anyone who is wishing to study the language in greater depth but would like a gentle introduction first.
The learning process is stress-free and fun. These CDs are so easy to listen to, as the background tracks are non-intrusive, rhythmical, and really do help to nudge the words and phrases into your memory. Everything is repeated several times, with one presenter speaking English and the other saying the same things in the target language. Everything is delivered in time to the music, which aids recollection later, there is good use of humour now and then, and all phrases are broken down so that you can see exactly how they have been made up. The emphasis is on repetition, so there is no feeling that things are moving too quickly. The idea is that you just relax, rather than straining to follow a fast-moving coaching CD. It really does work - once you have listed to the CD a few times, you will find you are remembering whole phrases.
