I just bought The Best Of Crosby, Stills and Nash songbook by Hal Leonard Publishing I went to play Suite: Judy Blue Eyes (the song I bought the book for) and I saw the song was in Open E5 Tuning. I have a cheap ($50 dollar) guitar and I have had problems with the bridge (it came up once) so I was wondering if tuning it to open E5 is a smart thing to do. P.S. I also don't know for Open E5(low to high: E,Eb,E,E,B,E) do you tune up or down? Please help!! Thanks.
Open E5 seems similar to open E, which I use a lot for Stones songs (and for that awesome song that Garcia gave to the Airplane, Comin' Back to Me!)
In Open E, you tune up, tune the A up to B, the D up to E and the G up to G#. For open E5, I would assume (someone correct me if I'm wrong) you tune the A down to Eb, the D up to E and the G down to E
Since you're only tuning the D up, it might not be too bad, but I would be careful and probably not do it if it was my only guitar. Open tunings can be fun, but you would only play that one song in that tuning, so it's a pain to retune every time or to leave your guitar in an odd tuning.
