It seems likely, although it is not absolutely certain, that the piano would have retained its ancient keyboard basso continuo role in the orchestral tuttis of the concertos, and possibly in other places as well.
Parece probable, aínda que non sexa absolutamente seguro, que o piano puido ter conservado o seu antigo papel de baixo continuo nos tutti orquestrais dos concertos, e posiblemente, tamén noutras pezas mozartianas.
