I began making Ukuleles about 5 years ago to use the smaller pieces of wood I had left over from guitar building. Ukuleles come if four sizes. Soprano, Concert and Tenor sizes all tuned a forth above normal guitar tuning (C-G-E-A) and Baritone, tuned like the top four strings of a guitar (D-G-B-E). Each size has a slightly increasingly larger body and a scale-length that increases by one inch. I primarily build the Portuguese (guitar-shaped) design in a concert size with a tenor neck to add more energy to the instrument. This is the most popular style with Hawaiian players.
The Kamaka Ukulele Company in Honolulu, designed a new oval-shaped body style called a Pineapple Ukulele. ( The prototype was actually embossed and painted to look like a Pineapple-Center Picture). A further refinement was to add up to four additional strings to the Ukulele for additional volume. Any Ukulele with more than four strings is called a “Taro” Uke indicating that it is a folk instrument. ( Taro is the root used to make the Hawaiian staple food Poi ).
