This is a Yamaha electric violin, featuring a unique design and a 5-string configuration. It's the Yamaha Silent Violin YEV105. As a silent violin, it's perfect for quiet practice at night in apartments where loud sounds are not permitted. Also, being an electric violin, it can be connected to an amplifier and effects pedals for loud performances in live houses and other venues. It's a 5-string violin, with the addition of a C string (like a viola) to the standard 4 strings, allowing for a wider range of notes.
