Can you help me spice up my guitar playing by suggesting a couple of alternative tunings? Especially for folk and country music.
1. Open D (Sebastopol or Vestapol tuning). Open D has a history going back to long before the first sound recordings and was later used by many old-time blues and country pioneers. Take the low E string down a whole step to D; the G string down a half step to F#; the B string down a whole step to A; and the top E down a step to D. The strings should now be DADF#AD. 
2. DADGAD (Celtic tuning). Very common in Celtic music and lends itself well to fingerstyle guitar. Take your low E down a whole step to D; tune the B string down a whole step to A; and the high E down a whole step to D. The strings should now be DADGAD.
