Upon opening the MusicVAE notebook, one is greeted with the following summary: “ MusicVAE learns a latent space of musical scores. The MusicVAE project is described in vivid technical detail via the corresponding research paper. Of the Colab notebooks made available by the Magenta team, the MusicVAE notebook fit the bill as being something that I could modify to serve as an AI conductor in the capacity desired. (All resources mentioned here are collated into a list at the conclusion of this article) The inclined reader could perhaps be stimulated by the additional Python Notebooks supplied by the Magenta team. Magenta can be used to manipulate music in a multitude of ways. Moreover, I wanted to output sheet music that musicians could fool around with. I sought to use machine learning to ‘mashup’ songs. I wanted to sample tracks of my choosing and layer them using a machine learning framework. Examples using Magenta to toy around with music (and art) exist. Magenta is a fun little library that uses TensorFlow as its machine learning workhorse. Google’s Magenta project being an example of this. The Experiment: Making an AI Composerįorays into the intersection spanned by AI and music are numerous, and have, in a sense, reached mainstream status. These AI-assisted compositions are then used to further train AI Composers, creating a cycle that renews itself symbiotically. People can then take certain elements and work them into their own, uniquely human, compositions. AI Composers present ideas to their human partners. This is the essence of the AI Composer: Machine learning tools are, at present, capable of detecting musical idioms and stitching them together in neat ways.Īccordingly, I envision a symbiotic relationship between AI Composers and their human counterparts. What is more, AI can be employed such that these machine-detected musical idioms are uniquely combined.
AI in particular can be leveraged to detect musical nuances that have hitherto existed beyond the bounds of human creativity. Machines can enrich our auditory experience. Can a machine be trained to compose songs, too? And if so, why would we want it to write music, anyhow? Drawing upon their prior auditory and emotional experience, talented composers seize our senses with their moving passages. In the traditional sense a composer stitches musical ideas together into song. Such a notion has only recently been given credence now that AI techniques have achieved nominal success: We are thus entering the age of the AI composer. The electronic analogue of the composer, however, is less defined. The electronic analogue of the performer has been around since the advent of the electromagnetic speaker. Expressed as formalized sheet music or intricately engrained in mental structure, all music is in a sense, composed. Others do it more methodically, such as a symphony orchestra, the sublime synchronicity with which the performers become united. Some do it spontaneously, like a jazz guitarist plucking an improvised solo with intoxicating brio. Electronic gadgets have afforded musicians an ability to shape their sound with mind-boggling variety. Advances in technology have dramatically restructured our musical landscape. Music has evolved alongside humanity, it is inexorably linked to our world view and the technology we use to generate it.
Not only does it move us, it moves with us. There is profound pleasure in observing groove machines in their element, becoming entranced by their beats, and humbled by their harmonies. I am by no means of this sort, however I am a devout supporter of live music. Some humans are living, breathing groove machines, musicians. However, if you’re intrigued by the notion of an AI composer and are curious as to the project’s inspiration and intent, indulge yourself by reading forth!īy the end of this article, you will be able to channel your inner (AI) composer.
If you’re looking for instant gratification: proceed directly to Go, don’t collect $200, and check out the corresponding Python Notebook, where you can play around and bring your very own AI Composer to life.
