I would appreciate any help I can get. The link provided is an image of a printing plate of a piano waltz my Great Grandfather wrote in 1898. I would love to hear what it sounds like. The image is from a printing plate that is nickel-plate and very reflective. Special thanks to @Nadesh for cleaning up the image and making it readable. I realize this may require a lot of effort, and all I can offer is my extreme gratitude for myself and my family.
My Great Grandfather, Lorenz Hager, was a concert composer and conductor in Austria, and reportedly could play every instrument in the orchestra. This is the only remaining piece that has survived in my family, as he never came to America and this was carried by my Grandmother when she immigrated here. Any help would be greatly appreciated.
