Acapella
Amish people do not play musical instruments because they believe it is a form of self-expression that leads to feelings of dominance and pride. The Ausbund, a High German songbook with no musical notation, is the basis for Amish church songs.
A Computer For The Amish
Believe it or not, there was a computer designed specifically for Amish communities. The Deskmate word processor lacks Internet access as well as video and music playback. Basic word processing, spreadsheets, and accounting can all be done on the computer. Because some (but not all) Amish use equipment that can only be used for industry, the Deskmate would not violate any long-standing Amish traditions.
