The sheet music was discovered by an heir who, after the authorship was confirmed, offered them for sale to the Liszt Memorial Museum and Research Center. 

The purchase was financed by a non-refundable loan from the National Cultural Fund, according to a press release sent to the Budapest Business Journal.

The documents include a piano work dedicated to the memory of Lisztʼs best friend in Hungary, Mihály Mosonyi, and a choral piece written for the inauguration of the Hungarian Royal Opera in 1884.

The works were published at the time, but the original manuscripts were considered lost. 

The music was published by a publishing house founded by József Parsch and Nándor Táborszky. Liszt formed a close friendship with Táborszky and, as it turned out, the manuscripts were kept at the company, which became state-owned after World War II.

The manuscripts will shortly be made available on the Liszt Ferenc Memorial Museum and Research Center website.
