In order to study the fate of mesons in thermal QCD at finite baryon chemical potential, we consider light mesonic correlation functions using the Taylor expansion to O((µ/T)2), in both the hadronic and quark-gluon plasma phases. We use the FASTSUM anisotropic fixed-scale lattices with Nf = 2+1 flavours of Wilson fermion. We find that mesonic correlators are sensitive to finite-density corrections and that the second-order terms indicate the chiral crossover in the vector and axial-vector channels.
