|Tenor Guitar (L), Baritone Ukulele (R)|
My tenor guitar is strung GDAE, from low to high. This is the same as standard tuning on a violin or mandolin, just one octave lower. So, my tenor guitar is not really a “guitar” at all, but more like an octave mandolin. When I pick a melody it I'm pretty much playing mandolin.
On the other hand, Laura’s baritone uke is strung DGBE, from low to high. This is the same as a regular 6-string guitar, minus the 2 lowest strings. So, her baritone ukulele is not really a “ukulele” at all, but more like a guitar with only 4 strings. When she strums chords she's pretty much playing guitar.
By that logic, the instrument that should have the word guitar in the title is the baritone ukulele. To the contrary, my experience playing tenor guitar tuned GDAE does not help me play a regular guitar, if at all, but I can pick up a left-handed mandolin and know what to do. Go figure.
