Linking a pair of pianos together produces a richer sound, say Bedii and Elif
Aran of Ankara, Turkey. They have filed a British patent application in which
two grand pianos are 鈥渢winned鈥� by a mechanical bridge which links their sound
boards (GB 2 322 467). As one piano is played, the twinned piano resonates in
sympathy. This, say the inventors, 鈥渋ntensifies the sonority more than twofold鈥�.
