Send a Piana to Havana is a nonprofit that arranges to have used pianos and parts shipped from the US to Cuba:
There's an aspect of the U.S. embargo on Cuba that we don't consider: Countless young musicians struggle on antique American pianos with strings long since rusted through, or on bad Russian pianos half-eaten by termites.
