the title says it all. i want to find resources for accrate sheet music (or at least guitar tabs) for classic rock songs, and i do not have much money, so free is best.

 

https://www.ultimate-guitar.com/ is a great place to start for tabs and chords. There are also lots of classic rock fake/real books, just hunt them down on google. Similarly you can find tab books for free if you search for them.

 

I would say the overabused and overevaluated musescore, but I think you know already.

The problem with most score sites is that many times the scores are (over) simplified (fake books) - so let's say instead of Db you find C. Not that huge problem, except if there are several modulations that risk to make things worse.

Here I found something for my purposes (Billy Joel), but you have to see yourself if it fits your requirements.
The Piano Notes

 

https://www.songsterr.com/ is the most accurate.

 

Nicely made site, for sure much better than musescore. However it's just for guitar(?)

 

It's for every instrument also available in guitar pro.

 

7 of my favorite sites to find tons of free sheet music for any instrument.

thank you all for your suggestions! i appreciate the members of this forum who provide helpful answers to questions.

 

Check the sister site for "site rip" and "tabs pack", those will yield a bunch of guit-pro files, which can be viewed as music notation
