The biggest fully operational tuba in service today is a BBB♭ contrabass tuba built in Markneukirchen, Germany in 2012. Over 20 local instrument makers worked together in 2012 to build a double-sized tuba in honor of Markneukirchen's 650th anniversary.  The Markneukirchen tuba stands 2.05m (80.71 in) tall and weighs over 50kg (110lbs).  For centuries the town has been famous for its musical instrument industry, and this gigantic tuba continues that tradition.  Here's Jörg Wachsmuth, a tubist in the Dresden Philharmonic, setting a world record on the Markneukirchen tuba for fastest recorded tuba performance of Rimsky-Korsakov's "Flight of the Bumblebee."
