i'm having trouble transitioning from playing an open chord to a barre chord on the ukulele. when i try to transition from the open chord to the barre chord the headstock always wants to fall. with a guitar you are wearing a strap which holds the guitar up, but with the uke there is nothing keeping the headstock up. am i the only one this is happening to? and i am holding the ukulele correctly, sort of tucked up under my arm, and cradling it with my bicep. any suggestions?
