Dear Mansab, I've done most of my transcriptions in either C or B tunings, with the bass strings in perfect 5THs, because the tunings have a fuller sound with the trebles-and since Bach's music praises God in an excellent and many times original way. Mozart said that C Major is the key of the gods. Also, Barrios used 6 in c, 5 in g in his transcription of Robert Schumann's Traumeri. In C Tuning, all the strings are in C Major, producing sympathetic vibrations. Also, the open 1ST string is the 3RD of the C Major triad. Additionally, with the strings I use, the deep harmonic texture is ideal, except for a little distortion on the 6TH string on a,b flat, and b-even then it can have a good effect; for example, in the Prelude Fr. BWV 829, in which the 6TH string is used a number of times in the higher positions. Also, the open 5TH string in g is ideal for many of Bach's pieces: BWV 655(transposed from G Major to C Major(subdominant) or G Major(BWV 719), also the Fugue Fr. BWV 1005, in which the tonic and dominant(6TH and 5TH strings)are used.                               The same use regarding harmonic texture is seen in the B Tuning: 6 in B, 5 in f#, 4 in c#.The only open string not in B Major is the 3RD string, but it is useful in B Minor, such as in the Toccata BWV 910, and the Ciaccona. Among other pieces in B Major is the Fugue BWV 552 For 5 Guitars, and the Nocturne Op. 55 Nr. 2 By Chopin For 2 Guitars. Respectfully, Lawrence October 2ND, 2007 rysenth3@...
