Franz Schubert was a composer who, it's very safe to say, was a musical genius. He composed many different types of works, especially short little songs for a singer & piano.
Below is a video of one of Schubert's short songs. Entitled "Die Forelle", or "the Trout". It is also the basis of a very famous Schubert string quintet. I'm not so sure about the accuracy of the German translation in this video, but It's good enough to be mostly accurate. Here is a simple, pleasant melody that tells the story of the trout & the fisherman. It's a catchy tune, too. So don't be surprised if you find yourself along the stream, tying on a dry fly while humming this tune.
