As is well known, the string spectrum comprises infinitely many states that can collectively be visualized along Regge trajectories of increasing mass and spin. Its massless and lightest levels, as well as certain higher spins including the leading Regge trajectory, have been the focus of past studies. In this talk, we will discuss new probes beyond the leading Regge, starting with the interactions of some of the lightest subleading massive spin-2 superstring states, explored in past work with Dieter Lüst, Pouria Mazloumi and Stephan Stieberger. We will then proceed to discuss a new way of organizing the string spectrum based on Howe duality, presented in recent work with Evgeny Skvortsov, which allows for a covariant method of excavating subleading string states and their interactions by entire trajectories, rather than individually.
