ResumoWe write Veneziano amplitudes for all reactions involving the $\ensuremath{\pi}\ensuremath{\omega}\ensuremath{\rho}\ensuremath{\sigma}{A}_{1}$ system, paying particular attention to kinematical constraints arising from spin. The minimal Veneziano amplitude for ${A}_{1}\ensuremath{\rightarrow}3\ensuremath{\pi}$ is shown to be dependent on two parameters, which may be related to the ${A}_{1}\ensuremath{\rho}\ensuremath{\pi}$ vertex. A discussion is given on how examination of the Dalitz plot may resolve the theoretical confusion surrounding the ${A}_{1}$.
