What’s a baryton?

In April 2022, the Valencia Baryton Project will be visiting us from Spain for a series of concerts with BaMM, featuring an instrument called the baryton.  The baryton will be played by Matthew Baker, and in this article from BerkleeNow, he talks about bringing this forgotten instrument out of obscurity.  Here is Baker playing this unusual instrument, which has six bowed strings and ten plucked strings, with Estevan de Almeida Reis, viola, and Alex Friedhoff, cello.
