The standard tuning for a baritone guitar is a perfect fourth lower than a typical guitar. So your low E is tuned down four steps to B. Your low A is tuned down to E and so forth with standard tuning being B E A D F# B. On a regular guitar, tuning this low would render your strings too loose to play but baritone guitars have a longer scale length which allows it to maintain a comfortable tension while keeping the tuning low.

This means that all the chord shapes and scales you already know are still usable on a baritone.
