A very interesting post.Firstly I believe that playing any second instrument is good for you, regardless of the tuning. Personally I am essentially a guitar player but I play the uke, mandolin, a tiny bit of fiddle, and bass guitar all in their respective tunings. Initially I found it hard to get my head around the chord shapes and the style "venacular" for those instruments. But what I did find was the refreshing and astounding difference in the note intervals of the chords. One of the first songs I did on the uke was San Francisco and singing the melody against the different chord "texture" was a blast. It improved my singing, and my guitar playing the more songs I learned. I did play what I called Bulls**t banjo by tuning the banjo to the last four strings of the guitar. I playing in the pit orchestra for the opera "Oklahoma" and I didnt have the time to learn all the chords(Eb, Bb, etc) because the music isnt written for Banjo. But the essence of the sound was there and added the right flavour to the play. So back to you in doing what works.DennisD
