  We give a direct harmonic approximation lemma for local minima of quasiconvex
multiple integrals that entails their $\mathrm{C}^{1,\alpha}$ or
$\mathrm{C}^{\infty}$-partial regularity. Different from previous
contributions, the method is fully direct and elementary, only hinging on the
$\mathrm{L}^{p}$-theory for strongly elliptic linear systems and Sobolev's
embedding theorem. Especially, no heavier tools such as Lipschitz truncations
are required.
