Makes perfect sense... but then it relys on there being a consistant amount of drop in pitch when second and third strings are coupled in, regardless of the note you are tuning. Still this is also the way I was taught, and there are other good reasons for doing this. I always end tho by checking an octave with all strings coupled. Even am able to clean up the lower note by checking its trichord against a single in the above octave. Tho you have to take into consideration the drop effect to get to the noise you want to clean up. Not too difficult tho, sorta like comparing thirds and tenths or other such test intervals in a sense. Richard Brekne I.C.P.T.G. N.P.T.F.
