Waits or Waites were British town pipers. From medieval times up to the beginning of the 19th century, every important British town and city had a band of Waites. Some other countries in Europe also had waits. They were called Stadtpfeifer in Germany and Pifferi in Italy.
The duties (things they had to do) varied in different towns and at different times in history. One of their most important jobs was to play at certain times of day so that people knew what the time was. They often played from the top of church towers. Sometimes they were also guards, watching from the towers so that they could spot any danger. They were like watchmen, making sure everything was all right (there was no police at that time). They woke people up in the mornings by playing music in the streets.
