MPA president Lauren Keiser said he wanted site owners to be jailed.
He said unlicensed guitar tabs and song scores were widely available on the internet but were "completely illegal".
Mr Keiser said he did not just want to shut websites and impose fines, saying if authorities can "throw in some jail time I think we'll be a little more effective".
The move comes after several years of bitter legal battles against unauthorised services allowing users to download recordings for free.
Publishing companies have taken action against websites in the past, but this will be the first co-ordinated legal campaign by the MPA.
The MPA would target "very big sites that people would think are legitimate and very, very popular", Mr Keiser said.
"The Xerox machine was the big usurper of our potential income," he said. "But now the internet is taking more of a bite out of sheet music and printed music sales so we're taking a more proactive stance."
