Speech Piano is about constructing a sentence in language. Also it is trying to relate German and English, two different languages and show how their "paths" overlap. While in search for the following word, one can experience the structure of a language, that sometimes feels like a maze. Finishing a sentence gives the pleasure of solving, while trying, failing or knowingly doing wrong can cause a humorous outcome. Enjoy, Harald
