Doo doo doot doot doo doot doo doo doo doo doo!
This question's title is the beat of the song in question. It sounds like it is played on an electric. piano of some kind.
As far as i know, it is from an American rock'n roll, or a similar genre, band from the 70's, 80's, or 90's. The beat is either medium or fast, It goes "Doo doo doot doot doo doot doo doo doo doo doo!" inside my head if did't see the title. It could be something like ACDC or The Who, or something along those lines.
