  We revisit the problem of a classical open string representing a meson in the
hard-wall geometry and consider the $S^5$ compact space. The existence of a
confining region due to the hard cut-off leads to a discrete set of string
configurations parameterized by the number of complete turnarounds $S^5$ great
circles. On the one hand, for a given angular momentum, there is a discrete set
of possible separations, and the confined quarks on the boundary are restrict
to a lattice. On the other hand, for a given separation in the confining
region, there is a discrete set of permitted values for the angular momentum.
The $q\bar{q}$ potential is linear for large separations, and the string
tension is very sensitive to the angular momentum.
