Guitar flash

Guitar hero on pc. https://guitarflash.com/

 

Cool flash game! If you're into guitar hero there's also a program called Clone Hero which allows you to play it and there are thousands of maps created by users that have some really cool and challenging stuff.

Also in a similar vein though focusing on very different genres are stepmania (DDR for keyboard basically) and osu!mania.

 

Yeah. guitarflash has also a lot of custom maps. If you cant find them in their database, you can search for it. For an example: "Unravel - Tokyo ghoul guitar flash"

PS: Guitarflash is online and uses flashplayer, however for clone hero you need to download a software.
