"Copedent is a table used to describe the tuning and pedal arrangement on a pedal steel guitar. The term was coined by Tom Bradshaw in an early 1970s article in Guitar Player magazine. It is short for "ChOrd PEDal arrangemENT". According to Bradshaw, the term is pronounced "co-PEE-dent". A complete copedent includes string gauges, and whether a string is plain or wound. A complete copedent also indicates the degree to which a string is altered, using "+" to indicate a half-step raise, and "-" to indicate a half-step lower."
