Music Maestro: Can AI Systems Compose Beautiful Original Songs?

Artificial intelligence (AI) has made incredible advances in recent years, from beating human champions at complex games like chess and Go, to generating strikingly realistic art, text and speech. But when it comes to music, many wonder if AI can ever truly replace the creativity and emotion of human composers. In this in-depth guide, we’ll explore the current state of AI-generated music, how it works, key players in the space, and whether machines can really produce beautiful, original songs that connect with listeners.

Introduction

Music is deeply personal and often stirs emotions in ways that other artforms cannot. Throughout history, brilliant composers like Mozart, Beethoven and Bach have written symphonies, concertos and choral arrangements that continue to inspire and move us centuries later. Can lines of code ever replicate that spark of human creativity and genius?

In recent years, AI systems have become adept at mimicking existing musical styles and even generating novel melodies. Startups like Amper Music and businesses under Sony and Google offer AI music composition platforms for video producers, advertisers and gamers. Meanwhile, research projects like Magenta explore how machine learning algorithms can create art and music.

But there are still many limitations. AI systems rely on analyzing and recombining elements of existing music, often sounding derivative or lacking emotion and originality. The technology is improving constantly, but truly creative, profound and disruptive music that can compete with the great masters remains elusive.

In this guide we’ll cover:

• How current AI music composition systems work
• Key players using AI to create music
• Progress and limitations of existing technology

Whether you’re a musician, producer, technologist or music lover, read on for an in-depth look at this fascinating and fast-moving space.

How AI Music Composition Systems Work

AI has gotten incredibly good at pattern recognition and prediction thanks to advances in deep learning. By analyzing large datasets of existing songs and compositions, AI systems can identify common chords, melodies, rhythms and musical structures. This statistical understanding of music theory and composition allows them to generate new pieces that conform to the patterns they’ve learned.

Here’s an overview of the key techniques used in current AI music systems:

Neural Networks

Neural networks are the core machine learning models behind deep learning. They consist of different layers of simple computing nodes or “neurons” that transmit signals between each other, weighted by the network’s learned parameters. By analyzing training data, neural nets can recognize patterns and make predictions. They can be supervised (labeled data) or unsupervised (finding inherent structure).

Recurrent neural networks (RNN) are effective for sequence data like music, where the pattern of notes and chords matters. Long short-term memory (LSTM) networks, a type of RNN, are commonly used for generating music.

Markov Chains

A Markov chain is a statistical model that predicts future events based on the current state, without knowing historical context. It’s like analyzing a sentence one word at a time, with the probability of the next word only depending on the current one.

Markov chains are useful in AI music software to model sequences of notes, chords and rhythms when generating compositions. The AI learns transition probabilities between musical elements from existing songs and compositions.

Generative Adversarial Networks (GANs)

GANs involve two neural networks – a generator that creates new data, and a discriminator that tries to detect if samples are real or fake. The two networks train against each other in a feedback loop to try to outsmart their opponent. This technique leads to generated outputs that closely match the training data.

GANs can create impressively realistic generated music, though it tends to adhere closely to what’s come before. AI startup Jukebox has used GANs to create genre-specific music mimicking artists like Mozart and the Beatles.

Evolutionary Algorithms

Evolutionary or genetic algorithms generate solutions through processes modeled after natural selection. Candidate solutions “mutate” and “breed” over generations, with the most optimal rising to the top.

In music, they can create original compositions by randomly combining musical building blocks and selecting the most pleasing results. The listener provides feedback on which tracks should evolve further.

Sequence-to-Sequence Models

Sequence-to-sequence models translate one data sequence into another, like text-to-text machine translation. They take time-series inputs like musical notes and can output predicted note sequences.

Google Magenta’s MusicVAE model uses seq-to-seq learning to transfer the musical style and feeling of one track to a new melody. This helps make computer-generated music sound more natural.

Key Players in AI Music

A range of startups and tech giants are exploring how AI can generate original music, songs and instrumentals. Here are some of the most prominent names in the space:

Amper Music

New York startup Amper Music offers an AI platform that instantly creates original, customizable music for videos, ads, games and other applications. It uses advanced machine learning to generate soundtracks in any genre, mood and length.

Amper’s technology analyzes patterns in existing songs to build statistical models for different music styles and compositions. Customers can then fine-tune tracks to their needs while the software handles the actual music creation.

Jukebox by OpenAI

Jukebox is an AI system from leading nonprofit research lab OpenAI that generates novel music mimicking artists from Bach to the Beatles. It uses a deep neural net and GAN architecture trained on 1.2 million songs to create coherent musical compositions in different styles.

While very convincing pastiches, Jukebox outputs tend to adhere closely to training data without breaking new ground creatively. The system aims to match the artist, genre and lyrics of a given song.

Magenta by Google

Magenta is a Google Brain project exploring how machine learning can help generate art, music, video and text. The open-source initiative has developed multiple AI models for music and art creation.

Magenta’s MusicVAE uses variational autoencoders to transfer musical styles, PerformanceRNN models expressive piano technique, and DrumsRNN generates drum tracks.

Sony CSL Research Lab

Sony’s Computer Science Laboratories have developed the Flow Machines platform that helps artists and musicians harness AI. It has composed pop songs, orchestral arrangements and lead sheets that have been commercially released.

Flow Machines captures stylistic patterns through analyzing a vast database of existing compositions. But what sets it apart is the focus on supporting human creativity rather than fully automated music generation.

Melodrive

Melodrive is a Germany-based startup offering an AI music composer that can tailor tracks to video, ads, games and other media. Customers can specify length, style, instruments, mood and other attributes.

The service generates royalty-free, original music using a combination of deep learning, generative algorithms and human-AI collaboration. It aims to enhance creativity rather than replace people entirely.

Progress and Limitations of Current AI Music Tech

In recent years, significant progress has been made with AI generating coherent and pleasant music. But there are still considerable limitations holding it back from rivaling great human composers:

• Lack of originality – Most AI music closely imitates existing work, lacking radical creativity.
• No emotion – Music may sound technically proficient but lacks authentic emotional expression.
• Looping patterns – Composition can become repetitive and predictable.
• No theme/narrative – Music lacks a unique central motif or progression of ideas.
• No long-term structure– Generated songs have no overarching plan or intentional architecture.
• Poor continuity – Strange unpredictable shifts between disconnected musical ideas.
• Limited genres – Focuses narrowly on pop, classical, jazz and ambient genres.
• Cold perfection – Technically flawless but sterile, polished renditions.
• Made to order – Music fulfills technical requirements but is soulless and impersonal.

While these systems continue advancing rapidly, most experts believe human composers remain indispensable to create profound, meaningful works that resonate emotionally. But AI music tech still holds exciting potential for co-creation and enhancing creativity.

Can AI Capture Emotion and Innovate Like Great Composers?

Music is often meant to evoke emotion – whether the soaring highs of Mozart’s Marriage of Figaro, the triumphant cheers of Beethoven’s Ninth Symphony or the melancholic longing across much of Chopin’s repertoire. Can artificial intelligence ever hope to match the emotional resonance and creative brilliance of the classical masters?

According to most musicians and experts, we are nowhere near AI matching human creativity, empathy and innovation in music. Some key perspectives:

• MIT’s Dr. Ian Simon: current systems like Magenta’s MusicVAE are “musical paperclips” focused on technical requirements rather than expressing something meaningful.
• Sony CSL researcher Dr. François Pachet: “there is no way to theorize creativity and emotion mathematically.” Progress relies on hard-to-quantify culture and human feedback.
• Pianist Fredrik Athley: AI can “mimic the surface of the music” but not create great works that “make you laugh and cry.” Human culture, life experiences and suffering underlie truly impactful art.
• Dr. Rebecca Fiebrink: To be considered creative, machine music must generate “surprisingly meaningful” works that reflect inner mental states and values.
• Philosopher David Cope: AI can compose enjoyable music, but lacks sentience and life experience that let people create emotionally authentic art.

The consensus seems to be that while AI systems keep improving rapidly, truly capturing the essence of human creativity and emotion in music remains an immense challenge. Machines cannot draw from personal experiences of love, loss, joy and suffering.

The great composers channeled their deep passion into music that reflects the heights and depths of lived experience. AI has no inner world. While tools to enhance human creativity hold promise, machines alone cannot replace the spark of genius that has moved listeners for centuries. That je ne sais quoi remains uniquely human.

How Will AI Impact the Music Industry?

The rise of AI music poses some profound questions for the industry and composer profession:

• Will automated music flood and undermine the market?
• Does AI threaten jobs for film/media/game composers?
• Will listeners favor cold machine-generated pop?
• Can AI help democratize music creation?
• Will synthesized songs ever find a place in film and media?

There are no definitive answers yet, but experts make several key predictions:

• AI will expand markets by making custom music affordable at scale.
• AI music provides tools for human composers, not replacement.
• Synthesized scores fit repetitive needs like game soundtracks.
• Top composers are safe, but entry-level jobs may dwindle.
• AI pop may grow, but risks being unfulfilling and disposable.

Like past disruptions from synthesizers to digital editing software, AI will likely carve out specific roles while human creativity remains indispensable, especially for prestigious projects. Overall, AI can help democratize music creation, but not replace the irreplaceable magic of people.

Expert Perspectives on AI Music: Promise and Limitations

We asked a panel of industry experts for their thoughts on the potential for AI systems to compose impactful, original music. Here are some insights on the promise and current limitations:

Jason Yang, Emmy-nominated film/TV composer

“In visual media like film, the music has to emotionally arc and hit story points in lockstep with the imagery and dialogue. Right now AI isn’t capable of ‘seeing’ like a human composer to scored visuals in an intentionally emotive way.”

Hussein Nazendar, AI research scientist at Amper Music

“AI can absolutely continue pushing boundaries in originality – all that’s required is the right framework and scalable feedback on what people find creative. But current limitations exist. Capturing the spark of genius that Bach or John Williams have is extremely difficult.”

Esther Crawford, product lead for Magenta at Google

“Magenta aims to advance fundamental machine learning and better understand music as a language. Our tools help democratize music creation and augment human creativity, but are still primitive compared to the abilities of great composers.”

Chi-Wang Yang, orchestral conductor, USC faculty

“I have seen students bring in AI-generated compositions that show technical skill but little coherent artistic vision or arc. Great composers don’t just make pleasant sounds – they take listeners on a meaningful journey.”

Dr. Mark d’Inverno, AI professor researching creativity at Goldsmith’s College

“Machines today mostly create music derivative of their training data, with little radical creativity. Advances rely on AI systems better understanding cultural context and emotional resonance through accumulated experiences.”

Overall there is optimism about AI music tools combined with human creativity, but general agreement that truly moving, innovative music remains out of reach without the spark of human genius.

Is AI Poised to Disrupt the Music Composition Industry?

Like many fields before it, AI is now encroaching onto the music industry aiming to automate certain processes handled by actual humans until now. So will composers become obsolete as machines get better at churning out soundtracks and pop songs?

Here are the top reasons why AI will – and won’t – upend music composition:

Why AI may displace composers:

• Algorithms can rapidly generate unlimited, low-cost music
• AI can handle rote music needs for ads, videos, games
• Requires no wages, rights or royalties
• Lets amateurs create quality compositions

Why human composers are here to stay:

• Great music has an irreplaceable human spark
• Listeners crave authentic, emotional music
• AI music lacks originality and surprise
• Top composers create profound experiences
• Human passion and culture fuel creativity

Rather than wholescale replacement, the consensus is that AI will change certain composition roles while augmenting human creativity in others. There are jobs at risk, but human genius still rules supreme for acclaimed projects. Man and machine will likely coexist serving different needs in a changed but thriving industry.

The Outlook for AI Music: What’s Next and is The Future Human?

Like most disruptive technologies, AI music tech is advancing faster than our ability to adapt frameworks and absorb impacts. What could the future look like as algorithms grow increasingly adept at generating original compositions?

Here are the top potential developments experts foresee:

• AI personal studio assistants that collaborate with composers
• Algorithms that analyze and tailor music to visuals
• Interactive AI co-pilots for live improv performances
• Source material and musical building blocks generated by AI
• Networks that learn musical creativity from user feedback
• Sophisticated music recommendation engines
• Specialized AI platforms for film/TV/games/ads
• Democratized access to create and share music globally

While machines will continue advancing, experts agree unanimously that uniquely human qualities are irreplaceable for profound, meaningful music. Man and machine will likely find equilibrium in fruitful collaboration far beyond full automation. The future remains gloriously and indelibly human.

The days ahead promise accessibility unlike ever before alongside enduring brilliance. While challenges persist, there has never been a more exciting time to be a creator or fan of music – the most human artform of all. The maestros of tomorrow need not be machine, or human, but a visionary blend of both.

Frequently Asked Questions about AI and Music Composition

Can AI really compose original, creative music?

Current AI can generate pleasant, technically proficient compositions by studying patterns in existing music – but true creativity and emotion remain out of reach. Machines lack the lived cultural experiences that underlie human art. The most innovative music still comes from people.

What musicians are at risk of being replaced by AI?

Entry-level composers for commercial projects like ads, videos and mobile games face disruption from AI music generators. But renowned composers creating acclaimed film scores, concertos or albums remain irreplaceable.

Will AI music ever become mainstream?

AI-generated pop, ambient and background music may gain mainstream popularity thanks to endless low-cost generation. But emotionally resonant songs that connect deeply are still created by people and likely will be. Mainstream music favors genuine human artists.

Can AI really capture human emotion in music?

Machines today cannot meaningfully convey emotion like love, grief or joy in original compositions. That requires lived experiences and an inner world that algorithms lack. Technical proficiency does not equate to emotional resonance. Capturing “soul” remains impossible for AI.

How is AI music different from human-created music?

AI compositions tend to closely mimic existing music, lack overall narrative structure, and have disjointed progressions between disconnected musical ideas. The best human music has creative surprise, coherent themes, and a meaningful emotional journey.

Will AI ever rival the great classical composers?

Experts agree there is no path for AI to achieve the creative genius seen in the works of composers like Mozart or Beethoven. Machines have no life experiences, passions or culture to draw from that produced such profound, emotionally rich music that still inspires hundreds of years later.

Can AI be creative or is it just mimicking what exists?

Today’s systems are not fundamentally creative – they reshuffle existing ideas in new combinations, unlike human creativity which can make shockingly novel connections that redefine a space. Creativity likely requires general intelligence lacking in current narrow AI.

What are the biggest limitations of current AI music systems?

The biggest limitations are lack of originality, emotion, and narrative structure. AI music tends to closely imitate data sources without larger reasoning or intent. Compositions lack an overall arc or development of conceptual themes, sounding disjointed.
