Wheatstone - Symphonium
"Invented in 1829 by the physicist Charles Wheatstone, the famous discoverer of the electric "Wheatstone bridge," the symphonium features two characteristics that he later used in his concertina: the same notes at pressure and suction, and alternative distribution of the diatonic tones to the right and left hand (C is for the right hand, D for the left, E for the right hand, etc.). The chromatic tones are the buttons of the outer row. The two groups of twelve buttons on each side produce a chromatic range from c1 to d3 (lacking d#1). The form of the instrument recalls a sheng without pipes."
