Joe Satriani probably jumped the shark long ago…but this lawsuit is crap.
I listened to the comparison, and he’s being silly. That little melody is about the simplest, most obvious, most banal series you could think of, short of “three blind mice”. Why? Because it’s simple, easy, and obvious. Someone should sue Joe Satriani for playing a scale and ripping off, dunno, the Temptations or something. Or sue him for stealing Blue Cheer’s distortion.
Bottom line is that while those 3 notes may be the same, none of the follow-on melody is. It’s a simple call-and-answer, and the call is something roughly analogous to a musical, “So…what’s up?” And the answer is a musical, “Well, I went to the cleaners and picked up my jacket, but they couldn’t get the stains out…” vs “Well, I nearly crashed my car on the ice, but I pulled out of the spin in time…”
Joe’s claim is like someone claiming they patented the wheel. Or that this other person plagiarized me because he used “the” in the exact same position on the page I used “the”.
