ABSTRACT:
An adjustable keyboard stand adapted to simultaneously support more than one keyboard in front of a musician and allow for immediate access to all of the supported keyboards. The tubular construction of the keyboard stand, which completely disassembles for easy transportation and storage, includes two side supports with at least one cross spar supported therebetween by a pair of cooperatively acting clamping means mounted on the side supports. The configuration of the pair of cooperatively acting clamping means, which support the cross spar in front of the plane formed by the front of the side supports, allows the distance between the side supports to be varied, while also allowing for easy positioning, installation and removal of additional cross spars without having to disassemble the stand.
