Pedal steel copedent
The Emmons C6 copedent
10 strings · 5 pedals · 4 knee levers
A copedent is the map of what each pedal and knee lever does to each string. Players set theirs up differently, so if you’re not sure what yours is, press each pedal and lever one at a time and listen for which strings move — then compare with the chart below.

Copedent chart
Strings run top to bottom — string 1 is farthest from you. Each column shows the note a string moves to when that pedal or lever is engaged.
