I've abandoned the ukulele as a main instrument - except in certain circumstances
This is me at 2018.11.27
I discovered the Ukulele. What an awesome little instrument. I wish i had been wise enough in my youth to have understood just how great they are.
(2018 update: wisdom also to include when not to play the ukulele - nothing can turn people away from you as a musician more than "being a ukulele player" - unless you are quite good.)
I'd love to have a nice one like an LAG or wow! the Martin 5K Uke but the $30 Chinese one i have is ok for now :-)
(update: we now have two new ukuleles - a concert size from Artist Guitars in Sydney and a tenor cutaway from Vietnam - both are fine for the price
update - make that 3 - we also bought a Kala KA-ST - quite nice
i've also taken to playing a 1970's Kasuga tenor banjo Chicago tuned - i.e. same as a baritone uke)
The standard tuning for a Ukulele is like the high four strings of a Guitar (D G B E) capoed at the fifth fret.
(Note that my son gave me an idea - take the A string from a Classical Acoustic guitar, cut it in half and replace the Ukulele G string with it (i'm C tuned). Tune it an octave lower than normal - gives a much richer sound and makes it even more like a guitar to play - which makes it easier for me to get my head around.
note on that: I tried it for a while - it sounds good but i've returned to having a proper drone string - if all you do is strum or you want to pick out melodies then lowering the G (when C tuned) is great but if you want to make the most out of a uke then having a drone string is the way to go.)
Tuning (C tuning)
i use the circle of fifths - start anywhere and work your way around the circle - forward and backward, in and out
