Concert ukuleles fall in the middle of the pack when it comes to size, tone, projection and portability. What I love about concert ukuleles are that they're still a very portable instrument (being only fractionally larger than a soprano), whilst packing a bit more of a punch. For this reason, pineapple concert ukuleles are my favourite. Having a larger soundboard, they are quite loud, whilst still having a really well balanced and beautiful tone. A concert ukulele would suit a customer looking for a portable ukulele with lots of projection.
