I have just bought a tenor guitar. I intend using it to accompany myself on folk songs. There appear to be several tunings. The shop has tuned it to mandolin tuning. I already play acoustic guitar and soprano ukulele. I find the acoustic guitar a bit too big for me to be comfortable - I am five foot nothing with small hands. The soprano uke is nice and small for me and the tenor guitar is also small enough. I love the sound of the tenor guitar. Which is the best tuning for me to start off with?
