Music Patents
September 2nd, 2007
I discovered something sort of neat today while strumming guitar. Being a neophyte in music theory I’ll describe it like this, the major chord is on the left and the melody note is on the right.
D D
A C#
C C
G B
The melody walks down in half-steps while the chords progress down in full-steps interspersed with fifths.
I suppose I could continue this progression forever but I am less skilled on guitar than keyboard so I have no idea what it sounds like. Continuing. . .
A# A#
F A
G# G#
D# G
Playing with this idea led to a nice sounding and beginner friendly D A C E major chord progression. A random thought about software patents was enough to get me dwelling on the similarities of music and software.
An algorithm is usually defined as a set of steps or rules to solve a problem. A chord progressions obviously fits this definition since it is a sequence which solves the problem of harmonizing a scale or modulating tension through consonance and dissonance. If we consider the following analogies it becomes evident that (chord progression -> algorithm) is the only one that fails in the legal sense even though a chord progression is an algorithm.
- sheet music -> source code :: (ideas on paper, copyright)
- recording -> forked binary code :: (derivative work, copyright, reverse engineering)
- music theory -> computer science :: (math, unpatentable)
- instrument -> hardware :: (identity)
- chord progression -> algorithm :: (uh…?)
I have never heard of a patent on a chord progression. Google Patent Search for chord progression returns patents for algorithms which derive progressions from melodies but not the progressions themselves. A method can be patented and algorithms are methods, therefore algorithms can be patented.
If my problem was not to generate algorithmic music but instead to arrive at the tonic chord from a particular note in the melody the method would naturally describe a progression of chords. Suppose I worded my patent like this: A method to arrive at the tonic triad from the ninth note of a major scale. For some idiotic and historical reason a software patent must include a description of computer hardware. I would assume that my chord progression patent would require similar wording requiring it to be played on a physical instrument. The revised title might begin: Apparatus and technique to arrive. . .
Other musical methods that seem patentable include finger tapping a guitar, overdriven amplifiers, and strumming piano strings since these things were novel at one time. The patent system is opaque and arbitrary. It’s like a poker game where the players are allowed to edit their hand, but with an infinite number of suites and face cards. The game destroys innovation and transforms productivity into litigation.
I’ve never applied for a patent or been sued for infringement so it would seem that I’m either an arbitrary complainer or a disinterested third party. Unfortunately we are all hurt by the loss in market competition, increased litigation, and stifled innovation that is the direct result of frivolous software patents.

The solution in software patents lies in the software patents themselves: enforce them rigorously and without any leniency. The immediate result is that software development the world over [but not in China, the Chinese don’t care for stuff that stands in their way] comes to a screeching halt because nobody can develop code anymore without having a lawyer going over every keystroke they make.
That would force a debate about the [in]sanity of software patents in a real hell of a hurry.
Your idea for chord progressions is exactly what the world does not need. Anyone who wants to patent music [in whatever form, for whatever reason] attacks one of the fundamental expressions of the human condition. Something we’ve done since the first rhythmic banging together of two rocks. To patent something like that is nothing short of an insult to the species. We should not do it.

you’re thinking about the wrong level imo when you say “A method to arrive at the tonic triad from the ninth note of a major scale.” i think that would be like a path from one point to another, whereas an algorithm would be something to calculate a path from one point to another. Algorithms are often likened to recipes but you are talking about the food itself.

Really like your blog,thanks for sharing it with us.And I also like beats by dr dre.Today beats by dr dre happens to be a baton in audio/video components. Why are the Monster Beats so ample even bigger than accepted headphones? The solution, it seems, is all inside the complete top quality. So if you’re attempting to find a plentiful set of headphones, you would like to become abiding you are accepting the most beneficial previously mentioned for ones cash. Right here are some affidavit you really should accede Monster Beats headphones to acquisition out why some accede these the most effective babble cancelling headphones although some other individuals accept problems together with the superior. The Dr. Dre headphones accept a abysmal enveloping low-end bass; the bass sounds are affluent and full. The mid levels and vocals are obvious, apple-pie and sharp, as well as the highs are brittle and abstracted after whenever distorting or aural tinny.

Really like your blog,thanks for sharing it with us.And I also like beats by dr dre.Despite Monster beats headphones on your own provides a history of additional than two years, but no solid cartel to amusement Monster lightly,on account of the aboriginal department angle Studio,Monster come to be well-known,and now it is the more on income angle forged in The usa,that has additional than 10 types acclaimed articles or blog posts .Meanwhile, the Monster headphones is aswell the illustration of trendy blazon headset,behalfed with the rap asperse dr. Dre’s.And agreeable belvedere barrage mother Woman GaGa take part inside the style and design, even the Apple affiliation do awful acclaim , in addition,there are lots of stars in America’s ball trade and athletes accept Monster headsets, in case you are still allurement which angle LadyGaGa or Bryant are sporting, you might be currently out.
