a baritone is a six string (although Schecter now make 7string baritones) guitar, with a slightly longer scale-length than usual. My Ibanez is 28" rather than the usual 25,5"(Fender) or 24,75"(Gibson) length. This allows the guitar to be tuned to much lower tunings and for much heavier gauge strings to be used...very useful to have, but not as your only guitar.
