Taylor Baritone 8-String and 6-String guitars are tuned a perfect fourth lower than standard guitar tuning. To properly create the baritone’s lower, deeper range and still maintain normal string tension, the guitar requires a longer scale length (27 inches instead of 25 1/2) and strings with a heavier gauge. The intervals from string to string are the same as standard tuning, but on a baritone guitar, the 5th string is the same pitch as the low E would be in standard tuning. The Baritone 8-String and Baritone 6-String should never be tuned to any pitches higher than the chart shown. Doing so will increase the tension on the guitar, which could damage it.
