at Amish weddings. Older Amish hymns are monophonic, without meter, and feature drawn-out tones with slowly articulated ornamentation. Pennsylvania spirituals are more contemporary and include a wide variety of influences. Although a few Amish learn to play traditional instruments such as the harmonica or the accordion, instruments are not played in public. Thus, singing is usually unaccompanied. "Sings" or "Singings" are attended by young people approaching marriage-age. They are usually held in barns on a Sunday evening after a worship service and are an essential element in Amish courting practices as the young participants are encouraged to engage in social discourse between songs. While singing in church is in German, singing outside of the church is more often in English than in Pennsylvania German, even though the Amish know many traditional worldly Pennsylvania German songs. The most popular performer of worldly Pennsylvania German songs is John Schmid, who is also very popular among the Amish. Transport Amish people are more likely to die in traffic accidents when modern vehicles driven by non-Amish collide with the slower horse-drawn Amish buggies. In Pennsylvania between 2003 and 2013, over 600 buggy accidents took place. Levi Shetler, of the conservative Swartzentruber Amish, was reported to have been involved in fourteen crashes by the age of 54, with one fatality. Direct causes of these crashes range from cars using headlights that blind passengers and horse, to recklessness or texting by drivers of motorized vehicles. Non-resistance has led violent perpetrators to take advantage of Amish as in the case of the West Nickel Mines School shooting. Kidnapping by non-Amish is also a common crime against Amish youth.

Amish do not view technology as evil, and individuals may petition for acceptance of a particular technology in the local community. In Pennsylvania, bishops meet in the spring and fall to discuss common concerns, including the appropriate response to new technology, and then pass this information on to ministers and deacons in a subsequent meeting. Because of this flat governing structure, variations of practice develop in each community. High voltage electricity was rejected by 1920 through the actions of a strict bishop, as a reaction against more liberal Amish and to avoid a physical connection to the outside world. Petrol-powered farm equipment, such as tillers or mowers, may be pushed by a human or pulled by a
