I found something called Frankenstein and Me, but I'm not sure if it's the same film. Its IMDB page lists some things (sorta) similar to what you described.
Saving the world, one fret button at a time.

There was this movie i once saw as a kid about these two brothers who were close with their dad as they were fans of classic horror movies. After the brothers are caught sneaking in a Drive-in theater and returned home, they learn their dad has just died either due to a heart attack or accident. Missing him, the brothers and their friends try to make a Frankenstein monster to bring their dad back.
