Amplify only Piano Key Frequencies

I have an old record of my Grandmother playing the piano from 1937.  She is turning 100 next week and I decided to surprise her with a digital restored copy of her song. The piano is very quiet and there is a lot of static.  I have been sampling various static for removal (slowly chiseling away at about 4% every pass.)  It is sounding a lot better but still has a lot of static.  I know static is broadband and can be very hard to remove.  I would like to know if there is a way I could set some sort of filter for each piano key frequency, in turn I could cut out all of the other frequencies that do not fall within each key of the piano (hoping that the piano was actually in-tune in the first place). Then also be able to boost only those freqs. Like have EQ sliders for specific frequencies?  Thank you

    Not really.  Here's a chart that shows the frequency of each note on a piano:  Frequencies of Musical Notes, A4 = 440 Hz

    This, of course assumes the piano is perfectly tuned.

    The trouble is, the sound of the piano isn't just a series of single frequencies.  Each note also produces a range of harmonic frequencies which add to the sound--and that's before you consider playing chords which produce multiple fundamental frequencies, each with its own range of harmonics.

    I fear the only way to proceed is to keep chiselling away with Noise Reduction.  Depending on the exact noise, you may find a pass or two with the click remover will help--and some work in Spectral Frequencies might help as well.

    Finally, what you could also do is use that chart above and filter off all the frequencies above and below the piano's range.

    Happy birthday to your grandmother!
