Singing can help learn languages in several ways: it connects people across cultures, learning lyrics improves vocabulary and teaches phrases, and singing may reduce a foreign accent. Singing also allows practicing language skills anywhere through music players, and is more enjoyable than speaking as it improves mood and allows fully engaging physically.

1. REASONS TO SING
1. Music connects across cultures and can break down barriers.
2. Getting to know the music is getting to know the culture and language.
3. Learning the lyrics of a song helps you expand your vocabulary and
teach you some slang/typical phrases.
4. Singing can actually help you reduce your foreign-sounding accent!
5. You can take music with you anywhere and learn and practise it on the
move thanks to your MP3 player / mobile phone.
6. It’s fun! You can put your whole body into singing if you like and let
your hair down a lot easier than you would in many speaking situations.
You can really enjoy yourself by singing and it helps to improve your
mood. Life would be way cooler if people sang more! Did you ever
notice how happy everyone is in musicals?

2. So don’t be shy, and don’t worry if you don’t have a good singing voice and
enjoy yourself!
