The sound is simple...although in the hands of the masters, it can astonish you. http://www.youtube.com/watch?v=_3j-b35zkGw But for most of us, there is great pleasure in strumming a song to entertain ourselves or strumming a song to share with a friend or a grandchild.
The sound is soothing....although young musicians can beat out some funky rhythms. But the songs we like to sing come from years gone by. As far back as Elvis, singing "Blue Hawaii" or even further back to the 20s, when Ukulele Ike (Cliff Edwards) hit #1 in the charts with "I Can't Give You Anything But Love" and "Singing In The Rain." http://www.youtube.com/watch?v=wv6vBVJEeyM
