In an era characterized by the ever-increasing pace of life and the constant bombardment of information, anxiety, and stress have become pervasive issues in our society. The quest for innovative solutions to mitigate these mental health challenges has led us to several different paths, ranging from traditional therapies to lifestyle changes. Still, one emerging solution is quietly gaining ground: the implications of AI to resolve many of these issues. In the age of Innovation, we have already seen the impacts of AI disrupting fields from Healthcare to finance, and it is now venturing into the realm of Mental Health and, more specifically, anxiety and stress prevention. In a world where technology and innovation are reshaping our lives at an unprecedented pace, the marriage of AI and mental health holds the promise of a future where our most persistent demons — anxiety and stress — can be tamed with the help of algorithms and artificial empathy.

The world of music therapy

Music has long been recognized as a potent tool for emotional regulation and stress reduction. Countless studies have shown that listening to music can elicit a wide range of emotions, from relaxation to joy, and even reduce anxiety and depression. Music’s therapeutic qualities have been harnessed in various contexts, from clinical settings to personal playlists. The reason for this is the ability of music to communicate with your brain through the power of sounds. Various brain components are responsible for processing distinct elements of a song, such as its rhythm and tone. This then causes the activation of the regions of the brain that are associated with emotional responses.

One of the first things that happens when music enters our brains is the triggering of pleasure centers that release dopamine, a neurotransmitter that makes you feel happy. This response is so quick that the brain can even anticipate the most pleasurable peaks in familiar music and prime itself with an early dopamine rush. This response is SO remarkably swift, to the extent that our brains can anticipate the most delightful crescendos in familiar tunes. This phenomenon highlights the profound connection between music and our emotional well-being, showcasing how music has the extraordinary ability to evoke emotions and create a sense of joy and anticipation in our minds. It’s as if music has an innate ability to tickle the pleasure centers of our brains, enhancing our enjoyment and emotional experience.

How does AI relate to this

In April 2023, a seismic shift occurred in the music world when a highly anticipated single featuring Drake (featuring The Weeknd), titled “Heart on my Sleeve,” was released. The track garnered instant critical acclaim, but here’s the twist: Drake had no involvement in its creation. Instead, an anonymous artist harnessed the power of a free AI music generator to craft a synthetic rendition of Drake’s voice, seamlessly blending it with an artificial representation of The Weeknd’s vocals to produce this song. This motion COMPLETELY changed the ideology of how music can be produced.

In Drake’s case, his label got involved, and the song had to be removed. However, this was a great inflection point for us to think about the future impacts of AI-based music.

The Discovery:

One of the key advantages of AI-generated music for anxiety prevention is its scalability and accessibility. This accessibility is particularly valuable in a world where the demands of work and daily life often leave little time for traditional therapeutic interventions. The example above clearly demonstrates this, where a song can be tailored simply from learning from existing songs and can be modified to fit your needs and preferences.

An interesting thing to note is that every sound has a different impact on the brain.

Neuro Sound and Neurofeedback:

Ordinarily, our brainwave patterns remain beyond our conscious control, as we typically lack awareness of their current state. Nevertheless, we possess the capacity to exert influence over these patterns. By employing effective external conditioning, we can bring about gradual and lasting changes, provided that the feedback aligns with the exerted influence. This process of guiding brainwaves to attain specific states is called neurofeedback.

Within NeuroFeedback, we have NeuroSound; neuro-sound represents a type of neurofeedback that employs auditory stimuli like music, binaural beats, or positive affirmations to shape brainwave patterns toward our intended outcomes.

Imagine if we could utilize AI for NeuroSound to do things like limit anxiety.

Artificial intelligence can play a pivotal role in this process of NeuroSound. AI systems can analyze vast datasets of sound patterns and their effects on brainwave activity. They can identify the most effective auditory stimuli, whether soothing melodies or binaural beats, to induce desired relaxation and reduce anxiety.

Simply put, AI can analyze millions of songs, genres, and artists to create the best one for your current mood. It can also provide personalized recommendations and adjust the music’s tempo and intensity based on the user’s brain activity.

Here’s an Analogy to better understand the relationship of AI in Neurosound:

Think of AI’s role in NeuroSound as akin to having a personal chef with access to an immense pantry of ingredients and an exceptional understanding of your taste preferences. This chef not only knows the precise flavors that delight your palate but also comprehends the moods and occasions that call for specific dishes.

Similarly, AI delves into an extensive library of musical elements, much like the chef’s pantry. It examines a vast dataset of sound patterns, just as the chef has a deep knowledge of ingredients and their interactions. With this knowledge, AI can craft the perfect auditory “dish” for your current emotional “appetite.”

But How can AI do this….

1. Generative Modelling: A particular method that could be used would be Generative Modelling from Emotional Classifications. In this scenario, EEG data based on mood would have to be collected and preprocessed and then classified into a Neural Network. EEG and mood-related data are typically sequential, involving measurements over time. RNNs, particularly LSTMs, are well-suited for processing sequential data and capturing temporal dependencies. Therefore, this would be something that I would use. After a trained model of the user’s emotional data, I would implement WaveGAN. WaveGAN stands as a specialized generative adversarial network (GAN) architecture tailored for the creation of unprocessed waveform audio, including speech and music. GANs, a subset of deep learning models, operate with a pair of neural networks — a generator and a discriminator — engaged in a competitive training process. WaveGAN is uniquely engineered to excel in the generation of raw audio waveforms. In the WaveGAN model, the user's mood classification would act as the input. WaveGAN can then be trained on several audio samples to generate the best feedback based on the user's mood. This model will be implemented in a feedback loop, meaning that as the mood changes, so will the sequence of generated music to relax the end user.
2. AI Music Storytelling: AI storytelling through music involves integrating narrative elements into the composition process, where the music becomes a vessel for conveying stories, emotions, and evocative journeys. This innovative approach transcends the conventional boundaries of music, inviting listeners to an emotional odyssey enriched with narrative depth. AI algorithms can craft narratives that align with your emotional arcs. To do this, we could use OpenAIs Magenta. We will also need some emotional recognition from the user. In this situation, we could use a convolutional neural network that utilizes a webcam to analyze emotion and mood. We can Integrate emotion-driven narrative elements into the generative storytelling process. As the AI detects shifts in the user’s emotional state, the music can dynamically adjust, weaving a narrative that resonates with the user’s feelings. For instance, a surge in happiness might lead to an uplifting musical climax, while soothing melodies could accompany moments of calmness. Magenta provides a range of models and tools, including the MusicVAE (Variational Autoencoder) for creative music generation. This technology enables the AI system to not only compose music but also infuse it with narrative elements based on emotional cues.
3. NeuroFeedback-Enhanced Composition: This involves integrating real-time feedback from the user’s brainwave patterns to influence the generative music process. EEG (Electroencephalogram) data can be collected, processed, and fed into a neural network (to process and determine a tag from). By leveraging machine learning algorithms, the AI system can learn to interpret different brainwave patterns associated with various emotional states. The system dynamically adjusts its composition as the user experiences the music in response to the detected brainwave patterns. This closed-loop system creates a personalized and immersive music experience that aligns with the user’s emotional and mental state. Perhaps a dataset that associates specific music pieces with emotional descriptors could be curated to put this into perspective. This dataset serves as the training ground for the AI model to understand the emotional content of various musical elements. We can then use this to develop a comprehensive semantic tag set that captures different emotional dimensions, such as joy, sadness, excitement, or relaxation. These tags act as emotional markers for the music. A CNN architecture can then be implemented to analyze the spectrograms or other representations of music pieces. CNNs excel in capturing hierarchical features, making them suitable for extracting complex patterns from audio data. This method is very flexible as now we can attach this to a generative system or a music dataset to pick and choose from selected music that matches the EEG analysis.

What the Future Holds

The power of AI seems truly exciting; such innovations can be revolutionary in the mental health + sound space. However, embracing this harmonious future necessitates robust ethical frameworks. Striking a balance between personalized assistance and user privacy, along with ensuring global accessibility with cultural sensitivities, will make these innovations truly inclusive. The future of AI in such an aspect is bright. Still, the issue comes down to the “trust” factor and the comfortability of humans for adapting to and utilizing technology for such a fragile topic. As these technologies become integral to the user’s emotional well-being, parallel steps should be taken for privacy and ethics of this issue. After all, walking and moving forward is impossible using only one foot.
