A piano has been permanently installed at Pearse Station in Dublin.
It's to perk up commuters' moods on their journey to and from work.
Iarnod Eireann says you don't have to be Mozart to play it - and anyone can give it a go.

Artist Sarah Edmondson painted the piano in the colours of the sea.
She explains: "It's meant to represent the coastal route that the DART takes.
"It shows a giant octopus, you have the suggestion of the cliffs, and then obviously seagulls - which I think would be definitely significantly in Dublin".
