In the guitar world, there's constant discussion about body shapes and the effects they have on the sound, or the sound that each body shape is designed to produce. I posted this question thinking what does it mean that the Nunes/Dias shape has fallen out of vogue and resurfaces only now and then in "vintage" replicas? A nearly forgotten but revered link in the evolution of the uke? And yes, what about the pineapple, bell, and tear-drop shapes? There's just not much discussion about them in the uke world.
