"Mozart was very tidy. He wrote without making any changes. Beethoven on the other hand, that's another story," said Zdzislaw Pietrzyk, director of the library organising the show.
"His manuscripts were messy, there are crossed out sections, corrections. And that passion is reflected in his symphonies and music," he told AFP.
Krakow's Jagiellonian Library picks out a different selection of musical works from its vaults to display each year alongside evening concerts performed during the annual Beethoven Easter festival.
This year's collection of several dozen works by various composers, on display until April 22, includes a sketch for Beethoven's 9th symphony and the original handwritten score of Mozart's Piano Concerto No. 27 in B-flat major.
"You can really see that Beethoven was human and he did really, really suffer when he did not find the right idea again or when he changed his mind or he made a mistake," said German pianist Hinrich Alpers, who performed at this year's Beethoven festival.
"He was very, very upset and the way he crossed out things was very fierce and brutal sometimes. He even ripped the paper and had to glue in a new page," he told AFP.
The composers' distinct working styles build on a view also reflected in their appearances: Mozart always pictured with a perfect wig and Beethoven shown with a mad mop of hair.
Their manuscripts on show in Krakow were originally stored in the Prussian State Library in Berlin but the Nazis removed them during the Second World War to protect them from Allied bombing.
They were moved to a Benedictine monastery in Silesia, which after the war became part of Poland. They were subsequently transferred to Jagellonian University in Krakow.
Germany has for years called for the return of the manuscripts, but Poland argues it has legal ownership and points to its own losses.
Warsaw says it lost half a million works of art during the war that today would be worth around $20 billion (15 billion euros).
The Polish government returned several manuscripts to East Germany in 1977 as a gesture of goodwill between the two then communist states. Many Poles including musicologists, historians and politicians reacted with dismay.
Hinrich Alpers argues that the location is inconsequential as long as the manuscripts are visible.
"It's most important really that these things don't disappear in somebody's private collection in a vault or somewhere where nobody can see them or touch them anymore," he said.
