If it's in the public domain, I suggest searching at imslp. Org (International Music Score Library Project. ) Other places to look include cpdl.Org (choral public domain library) or http:/icking-music-archive.
Org/index. Php (werner icking music archive) If your music is not public domain, you will probably have difficulty finding it for free anywhere. Although copies may sometimes be available still, sites can be shut down for (knowingly) providing such, and no reputable database site such as the above will keep them available for any length of time.
If you're looking for something specific, from the last 100 years or so, you should just go to a music store and buy it Also you can try this resource, which I think id good enough reference: freeprintable. Com/free-printable-music You should check piano-sheets.Net - They have tons of free piano sheets! You can also find free video tutorials at purelessons.
Com At findfreesheetmusic.Com/pages/Piano there are a lot of links to free sheet music. People rate the sites. Some sites have some good public domain classical, holiday, and other public domain sheet music.
You may find some interesting music on some of the sites.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
