I've been playing the uke for many, many years. Got my first one in around l947 and have been enjoying ukulele playing every since. Presently there are seven uke's around the house. They are a very versatile instrument that can be used to play many styles of music. Recently I tried frailing, and 3 finger style blue grass picking (picking styles used on the 5 string banjo).   Frailing worked especially well on the uke.
        Last year I built three uke's in my shop. First attempt wasn't great but by the time I got to the third uke (one I built for my grandson) I produced one with a really great sound. Plan on building a few more next winter. Plans for a Martin uke are available from Elderly's plan department.   
        The concert size has a more mellow tone that I like for a typical Hawaiian sound. For ragtime era music I like the sound of the standard uke best.
