Here's a little song I wrote You might want to sing it note for note Don't worry，be happy In every life we have some trouble When you worry you make it double Don't worry，be happy Don't worry，be happy Don't worry，be happy Don't worry，be happy Don't worry，be happy Don't worry，be happy
Ain't got no place to lay your head Somebody came and took your bed Don't worry，be happy The landlord say your rent is late He may have to litigate Don't worry be happy Look at me I'm happy Don't worry，be happy I give you my phone number When your worried，call me I make you happy Don't worry，be happy
Ain't got no cash，ain't got no style Ain't got no gal to make you smile But don't worry，be happy Cos when you worry，your face will frown And that will bring everybody down So don't worry，be happy Don't worry，be happy now Don't worry，be happy Don't worry，be happy now Don't worry，be happy now Don't worry，be happy now
Now there this song I wrote I hope you learned it note for note Like a good little children Don't worry be happy Listen to what I say In your life expect some trouble When you worry you make it double Don't worry be happy Be happy now Don't worry，be happy Don't worry，be happy Don't worry，be happy Don't worry，be happy Don't worry，don't worry，don't do it Be happy，put a smile on your face， Don't bring everybody down like this Don't worry，it will soon pass whatever it is Don't worry，be happy I'm not worried
当电声乐器发展到饱和状态后，人们对木制原生乐器似乎多了几分持久的依恋，一场“why me 李宇春 unplugged ”（“不插电”音乐会）就是很好的明证。可是，如果音乐甚至连木制乐器都要舍弃，会是什么样子？聆听完这首a cappella（“阿卡贝拉”无伴奏演唱），您肯定有了一番新的感受吧？
A cappella源于意大利语，原指“教堂风格的音乐”，而cappella的词根则可追溯到“chapel”（小教堂）。从教会音乐发展史而言，虽然有伴奏的合唱可追溯至中古时代，但教会的合唱大体上以无伴奏居多。
