Computer-implemented method patents are not computer programs.
They may
cover computer programs, but they are not computer programs
themselves.
Computer-implement method patents describe functionality. A
computer program
may be an implement of a computer-implement patent.
Your analogy with a
piano breaks down when you consider that a player
piano is a single purpose
machine. It can only do one thing based on the paper
music that you feed it;
play piano music. In other words, the paper does
nothing to configure the
piano. In contrast, computers are general purpose
machines in that they can do
a variety things based on how they are configured
with hardware and software.
That is what people are trying to cover with
computer-implement method patents,
how the computer is configured based
mainly on the software installed on the
computer. Don't you think that
companies that develop advanced crypto or 3d
rendering software deserve
some sort of patent protection when they develop new
algorithms?
