Abstract
We uncover a relation between the scattering amplitudes of massive strings and the expansion of the massless string amplitude at tree level. More precisely, the n-point tree amplitude of n-1 massless and one massive state is written as a linear combination of n+1 massless string amplitudes at the order.
