‘But Mr Songsfromsodeep,’ I hear you say, ‘I don’t have a twelve-string guitar. Is there anything I can do to simulate one?’
Well, yes. There’s one thing.
Apologies to those who know this, since this is not in any way a new or innovative technique, but you can double a part played on a six-string guitar with the same part played on a guitar in Nashville tuning. Nashville tuning is when you take the four octave strings from a twelve-string (the low E, A, D and G) and put them on a regular six-string guitar. That means the D and G strings will be higher in pitch than the B and E strings, leaving you with a guitar that sounds jangly indeed. If you can tightly double the original six-string part on a recording, it will sound very like a twelve-string. D’Addario and Martin do a ‘high-strung/Nashville tuning’ set (10-27 and 10-25 respectively), and possibly other manufacturers do too.
You don’t need to present Nashville-tuned parts in this way, though. Try panning the two parts left and right to create a stereo version of the effect. To hear examples of both techniques, have a listen to Hips and Makers and Strange Angels, the first two solo albums by Throwing Muses/50 Foot Wave singer/guitarist Kristin Hersh. Examples of Nashville-tuning parts are numerous on Strange Angels; you’ll have to hunt harder for them on Hips and Makers but they’re there (on Velvet Days and Teeth, at least, I think).
You can also hear Nashville tuning on on many, many country records. Where’d you think the name came from?
Kristin Hersh, 2006 (Dina Douglass). Guitar probably not in Nashville tuning.
