I am wondering if anyone has ever given thought to playing the mandolin as a ukulele by changing the tuning to what would be low G, then change the D to a C and switch the A and E strings. MandoIin is tuned G, D A, E. I would imagine you could probably change the tuning of a ukulele to mandolin by reversing the process but you would have to learn new chords. What I am thinking is this would give you an eight string ukulele of sorts kind of like guitarists have twelve string instruments. I am not sure you can do the harmonic tuning like a twelve string but am wondering if you can and if it would be a good thing. Thoughts?
