The Cadeironcello is an innovative tool designed by MISSOM®. This is one set stylized, where we can find several tools coupled, but it is not easy to characterize it. This musical chair includes a drum wood at top, one adufe skin and 10 strings on the back. This set of strings allows them to be individually rubbed with a bow or plucked, ranging from the low strings, cello, guitar and ukulele. It comes with a tuning system for tuning pegs. This instrument was produced to Drumming GP, for the event "Art On Chairs" in Paredes, Portugal (Nov/2012).
