There's an interesting phenomena of baritones and tenor guitars sharing 4 strings and occassionally what I like to call DoGBonE tuning. Although more commonly known as Chicago tuning, DGBE.
www.tenorguitar.com indicates the standard TG tuning as CGDA. But also mentions other possible tunings.
Chip Jones in his book Blues for Tenor Guitar takes care of both tunings in the same spiral bound blues lesson book. The cover indicates the lessons are in standard notation and tablature. Inside it is clear that a lot of effort has gone into progressively exploring the blues. Each chapter has CGDA along with an equal compliment of DGBE.
