  We have investigated the spin-orbital angular momentum correlations for the
active quark inside the light and heavy mesons for both the spin-0 and spin-1
cases. These correlations can be derived from the generalised transverse
momentum dependent distributions (GTMDs) as well as the generalised parton
distributions (GPDs). We employ the overlap representation of light-front wave
functions in the light-front quark model (LFQM) to calculate our analytical
results. The dependence of spin-orbit correlations (SOCs) on the longitudinal
momentum fraction $x$ as well as the transverse momentum dependence
$\mathbf{k}_{\perp}$ has been graphically presented. Even though the SOCs have
already been studied for the spin-0 pions and kaons in other approaches, no
calculations for the other light and heavy spin-0 mesons have been reported in
literature. Further, the correlations for any of the light and heavy spin-1
mesons have been studied for the first time in the present work.
