An Amateur Concert is an 1882 oil painting on canvas by the Portuguese painter Columbano Bordalo Pinheiro.

[1] Five people are singing and playing in the dark: Maria Augusta Bordalo Pinheiro, the artist's sister, in a white satin dress; next to her, the painter Adolfo Greno in right profile; then an Italian singer in a dark suit; in the background Josefa Greno, in a three-quarters view, looking down; and on the far right another painter, Artur Loureiro, at the piano.

[1] The large painting was presented at the 1882 Paris Salon under the title Soirée chez lui.

It is friendship that unites them both in painting and music, though a shadowy unknown figure next to the piano is watching.

In France it was not received well, and in Portugal there was controversy about the abstract and vague figures.
