I have been interested in seeing the classical guitar’s repertoire expanded ever since I first heard Vincenzo Macaluso play keyboard transcriptions on his 10 string guitar made by José Oribe.
I’m sure that this is not an original idea, but I’m wondering if anyone has strung up a couple of regular six string guitars, one as an “A” guitar with the first string being an appropriately smaller gauge and tuned to A 440. The other five strings would be displaced down so that the sixth string is now filled with what would normally be a fifth string, tuned to A 110.
With the “B” guitar, you would do just the opposite. Add an appropriately larger gauge string as the sixth string, and tune it to the B below the normal sixth string E. The other five strings would then be moved higher by a notch, and the first string position would then be filled by what would normally be the second string B.
No special guitars required!
For a duet this would allow coverage of a a lot of great keyboard music. For instance, my wife who is a classical pianist, went over the Chopin preludes, and found that the extended range of such an arrangement would cover 23 of the 24!
Would appropriate arrangements of keyboard music be hard to find? Other difficulties?
