As one of the many software developers who are also musicians, I have always been fascinated by the frequent bundling of the gifts and passions for these two endeavors and what they have in common. I have always said that writing code and writing music feel a lot like the same process to me, like they’re using the same parts of the brain. Music and code are certainly similar in many ways. Both need structure and coherence. Each work must be unique in some way, or it is meaningless. Both must follow some set of rules. What set of rules to follow is a creative choice. Sometimes you can even make up your own rules, but failure to follow them will pose a threat to the cohesion of the work. Once the rules are established, you may occasionally, carefully, and mindfully, make some real magic by breaking them.
But what about the work that we consider to be truly significant? In the music world we still study Stravinsky, Mendelssohn, Beethoven, Mozart, Bach, Gabrieli, even Gregorian chants, not as nostalgia, but as work that is still relevant and valuable today. Where is this reverence for history in software? What is the difference? Is it in the platform evolution? Each new computing device to hit the market seems to render last month’s model instantly obsolete. The arsenal of musical instruments over the years has progressed more by expansion than by evolution. The new does not generally displace the old. We’ve added saxophones, steel-stringed guitars, drum kits, electric pianos, electric basses, synthesizers, and on and on, but the symphony orchestra still looks pretty much like it did three hundred years ago.
This is one of the things that I find so fascinating about all the recent movement in the field of functional programming. It’s old! LISP was developed in the 1950s, and we’re studying this approach today not because it tells where we’ve come from, or because we have fond childhood memories of it, but because it is valuable to us right now. I have never seen this happen before in this field. Maybe it’s just because I’m getting old, but I’m intrigued and excited to see “the new hotness” can be something that is older than I am.
