This article explores the neurodynamics of Indian classical music, focusing on how its structured patterns—particularly the Pallavi–Anupallavi–Charanam format—modulate auditory processing, emotional regulation, neuroplasticity, and cognitive function.
Drawing on the ancient practice of formulaic chanting and the Sri Amit Ray's 28 Brain Chakras framework, which extends beyond the traditional seven chakras to include specialized neural energy centers, we studied the ICM's rhythmic and melodic patterns resonate with neural oscillatory networks, enhancing neuroplasticity and emotional well-being.
Indian classical music (ICM), with its intricate Pallavi–Anupallavi–Charanam structure, represents a sophisticated auditory stimulus that engages complex neurocognitive processes. By integrating neuroimaging data, computational neuroscience models, and brain fluid dynamics, we observed that ICM's unique structure acts as a neurocognitive scaffold, facilitating synchronized brain activity across auditory, limbic, and prefrontal regions.
This work bridges the classical musical practices with modern neuroscience, offering insights into therapeutic applications for neurological disorders and mental health.
Indian Classical Music
Indian classical music (ICM), encompassing Hindustani and Carnatic traditions, is a profound cultural and artistic system rooted in ancient Vedic practices [1]. Its compositional structure, notably the Pallavi–Anupallavi–Charanam framework in Carnatic music, organizes melodic and rhythmic elements into a dynamic progression that captivates listeners and performers alike. Unlike Western musical forms, ICM emphasizes improvisation within a raga (melodic framework) and tala (rhythmic cycle), creating a rich auditory experience that engages both cognitive and emotional faculties.
Recent advances in neuroscience have highlighted music's capacity to modulate brain activity, influencing auditory processing, memory, and emotional regulation [1, 2]. ICM, with its repetitive yet evolving formulaic patterns, offers a unique lens to study neurodynamics—the temporal and spatial patterns of neural activity that underpin cognitive and emotional processing [2].
The practice of chanting, integral to ICM's spiritual roots, aligns with the Sri Amit Ray's 28 Brain Chakras framework, which conceptualizes 28 or 114 specialized neural energy centers beyond the traditional seven chakras, influencing neural and energetic systems through vibrational resonance [3].
Additionally, computational models of brain fluid dynamics, such as those involving cerebrospinal fluid (CSF), interstitial fluid (ISF), and cerebral blood flow (CBF), provide a novel perspective on how ICM might influence brain homeostasis and neuroplasticity [4].
This article investigates how ICM's structural components, formula patterns, chanting practices, and their potential interaction with brain fluid dynamics affect auditory processing and neural oscillatory networks, proposing a model for their therapeutic potential.
The Pallavi–Anupallavi–Charanam Structure
The Pallavi–Anupallavi–Charanam structure is a hallmark of Carnatic music's kriti form, a compositional genre that balances thematic consistency with improvisational freedom. The Pallavi introduces the main melodic theme, often repeated to establish familiarity. The Anupallavi, a secondary section, provides contrast by exploring higher pitch ranges or alternative raga phrases, enriching the composition's emotional depth. The Charanam, typically the longest section, elaborates on the thematic material with intricate rhythmic and melodic variations, often concluding with a return to the Pallavi.
This tripartite structure mirrors cognitive processes such as encoding, elaboration, and consolidation. The Pallavi's repetition primes auditory memory, the Anupallavi challenges attentional networks with novel stimuli, and the Charanam's complexity engages higher-order cognitive functions like pattern recognition and emotional integration [1]. Neuroimaging studies suggest that such structured auditory stimuli activate the auditory cortex, hippocampus, and prefrontal cortex, fostering cross-regional synchronization.
🎼 Pallavi – The Root Mantra
The Pallavi is the central refrain—the melodic and lyrical theme that repeats throughout the piece. It encapsulates the core emotional or devotional message, serving as an anchor for the entire composition.
-
- Neurodynamic role: Anchors attention; repeated exposure strengthens memory and learning (via hippocampal circuits).
- Activates the default mode network (DMN) during passive listening and helps establish emotional familiarity.
- Functions like a musical mantra, reinforcing neural patterns through repetition [1].
- Brain wave alignment: Aligns with Alpha (8–12 Hz) and Theta (4–8 Hz) waves, initiating calm focus (Alpha) while supporting memory consolidation and emotional familiarity (Theta) [2].
🎶 Anupallavi – The Emotional Lift
Following the Pallavi, the Anupallavi provides contrast, expansion, or elevation. Musically, it often climbs to a higher pitch or explores a different register of the rāga.
- Neurodynamic role: Triggers the limbic system, modulating emotional arousal.
- Offers novelty and surprise, increasing dopamine release and cognitive engagement.
- Enhances cross-hemispheric communication, especially in trained musicians [1].
- Brain wave alignment: Evokes Beta (12–30 Hz) waves, not allowing to sleep, for cognitive engagement and Theta (4–8 Hz) waves for emotional arousal, building emotional and cognitive engagement [2].
🎵 Charanam – The Narrative and Integration
The Charanam is the storytelling section, often more elaborate, and includes philosophical or devotional verses. It brings depth and diversity while always returning to the Pallavi.
- Neurodynamic role: Stimulates executive networks, including the prefrontal cortex, as listeners process complex verses.
- Invites emotional synthesis and empathic imagination, activating the insula and temporal lobes.
- Provides a conclusive loop that allows the brain to rest in pattern recognition and closure [1].
- Brain wave alignment: Primarily resonates with Gamma (30–100 Hz) waves, enabling insight and aesthetic bliss, with Theta (4–8 Hz) waves contributing to deep absorption and emotional synthesis [2].
Formula Patterns in ICM
The Pallavi–Anupallavi–Charanam structure is governed by formulaic patterns that provide a scaffold for both composition and improvisation. These patterns include specific melodic motifs (sangatis), rhythmic cycles (talas), and gamaka (ornamentation) techniques that define a raga's emotional and structural identity.
For instance, sangatis in the Pallavi involve iterative variations of a melodic phrase, each subtly altered to enhance expressivity, which aligns with neural mechanisms of predictive coding [1]. The Anupallavi often introduces a complementary melodic contour, adhering to the raga's ascending ($arohana$) and descending ($avarohana$) scales, which may modulate emotional arousal through pitch transitions. The Charanam integrates these elements with complex tala subdivisions, such as tisra (three-beat) or chatusra (four-beat) nadais, engaging temporal processing networks.
These formulaic patterns are not rigid but allow for improvisation within constraints, a feature that distinguishes ICM from other musical traditions.
The Pallavi aligns with Alpha waves, initiating calm focus and setting the theme. The Anupallavi evokes Beta or Theta waves, building emotional and cognitive engagement. The Charanam resonates with Theta or Gamma waves, enabling deep absorption, insight, and aesthetic bliss.
This hierarchical structure may resonate with neural oscillatory hierarchies, where low-frequency oscillations (e.g., $\delta$, $\theta$) modulate higher-frequency $\gamma$ activity, facilitating cognitive integration [2].
$$ \text{Neural Oscillation Hierarchy: } \delta(0.5-4 \, \text{Hz}) \rightarrow \theta(4-8 \, \text{Hz}) \rightarrow \gamma(30-100 \, \text{Hz}) $$.

Relevant Datasets for ICM Neurodynamics
Publicly available datasets can facilitate the study of ICM's neurodynamic effects, particularly in the context of the Pallavi–Anupallavi–Charanam structure. Datasets like those hosted on platforms such as Zenodo or OpenNeuro could support computational modeling of raga and tala structures or provide EEG responses to raga-based stimuli, offering insights into oscillatory patterns during ICM listening. Researchers can integrate these datasets with computational tools, such as gammatone filterbanks, to model auditory cortex responses to ICM's formulaic patterns [1]. These resources enable hypothesis-driven studies on how ICM's structural complexity influences neural synchronization and emotional processing.
Neurodynamics of Auditory Processing in ICM
Auditory processing of ICM involves a cascade of neural events, from primary auditory cortex activation to higher-order integration in association areas [1, 2]. The raga's microtonal variations and tala's rhythmic precision engage the brain's temporal processing networks, particularly the superior temporal gyrus and basal ganglia. EEG studies indicate that ICM listening increases $\alpha$ (8–12 Hz) and $\theta$ (4–8 Hz) band activity, associated with relaxation and focused attention, while also modulating $\gamma$ (30–100 Hz) oscillations linked to cognitive integration [1, 2].
The Pallavi–Anupallavi–Charanam structure imposes a temporal hierarchy that aligns with neural oscillatory dynamics. For instance, the Pallavi's repetitive sangatis may entrain low-frequency $\delta$ and $\theta$ oscillations, facilitating memory consolidation [2]. The Anupallavi's melodic shifts could modulate $\beta$ (12–30 Hz) band activity, reflecting heightened attentional demands. The Charanam's rhythmic complexity, driven by intricate tala patterns, likely engages $\gamma$ oscillations, linked to cognitive integration and emotional processing [2]. This oscillatory entrainment hypothesis, supported by recent neurodynamic models, suggests that ICM acts as a neurocognitive scaffold, synchronizing distributed brain networks [2].
$$ \text{Entrainment Model: } f_{\text{tala}}(t) \propto \sum_{k} A_k \sin(2\pi f_k t + \phi_k), \text{ where } f_k \in \{\delta, \theta, \beta, \gamma\} $$
Brain Fluid Dynamics and ICM: A Computational Perspective
The neurodynamic effects of ICM may extend beyond neural oscillations to influence brain fluid dynamics, including cerebrospinal fluid (CSF), interstitial fluid (ISF), and cerebral blood flow (CBF). Computational models suggest that rhythmic auditory stimuli, such as those in ICM, could modulate brain fluid dynamics by altering intracranial pressure and facilitating the clearance of metabolic waste through the glymphatic system [4]. The Sri Amit Ray's 28 Brain Chakras framework posits that vibrational frequencies from music and chanting can resonate with neural energy centers, potentially influencing fluid dynamics in the brain [3]. For instance, the low-frequency oscillations ($\delta$, $\theta$) entrained by the Pallavi's repetition might enhance CSF pulsations, promoting glymphatic flow and supporting neural homeostasis [4].
Ray's computational model of brain fluid dynamics indicates that CBF oscillations, driven by rhythmic stimuli, can enhance oxygen delivery to neural tissues, supporting cognitive and emotional processing during ICM listening [4]. This interplay between auditory stimulation and brain fluid dynamics offers a novel mechanism through which ICM may exert therapeutic effects, such as reducing neuroinflammation and enhancing neuroplasticity [2, 4]. Future studies could integrate neuroimaging with fluid dynamics simulations to explore how ICM's rhythmic patterns influence CSF, ISF, and CBF, providing a holistic understanding of its impact on brain health.
Ancient Formula Chanting and Neural Resonance
Chanting, a cornerstone of ICM's spiritual context, involves repetitive vocalization of mantras or melodic phrases, often aligned with specific ragas and talas [3]. Ancient Vedic texts describe chanting as a means to harmonize body and mind, a concept echoed in modern music therapy [3]. The Sri Amit Ray Brain Chakras framework posits that chanting at specific frequencies activates specialized neural energy centers, influencing neural activity through vibrational resonance [3]. These vibrations may also interact with brain fluid dynamics, potentially enhancing CSF flow and supporting neural health [4].
Neurophysiologically, chanting induces a meditative state, reducing cortisol levels and enhancing parasympathetic activity [3]. EEG studies reveal increased coherence in $\alpha$ and $\theta$ bands during chanting, suggesting enhanced functional connectivity between the prefrontal cortex and limbic system. The rhythmic entrainment of chanting may also modulate the default mode network (DMN), promoting introspection and emotional regulation [2]. In the context of ICM, chanting within the Pallavi–Anupallavi–Charanam structure amplifies these effects, as the music's formulaic patterns sustain engagement while the chant's repetition fosters neural stability.
The Sri Amit Ray 28 Brain Chakras Framework
The Sri Amit Ray Brain Chakras framework integrates ancient Indian philosophy with modern neuroscience, proposing that specific sound frequencies correspond to specialized neural energy centers, distinct from the traditional seven chakras [3]. While the traditional seven chakras (Muladhara, Svadhisthana, Manipura, Anahata, Vishuddha, Ajna, and Sahasrara) are primarily associated with spiritual and energetic functions along the spine, Sri Amit Ray’s model expands to include 28 or 114 brain-specific chakras. These are conceptualized as neural hubs that modulate brain network dynamics, influencing cognitive, emotional, and sensory processing through vibrational frequencies [3]. This framework emphasizes neuroplasticity, suggesting that targeted sound frequencies, such as those in ICM, can rewire neural circuits to enhance cognitive flexibility and emotional resilience [3, 2].
For example, the Anahata (heart) chakra, linked to compassion in both traditional and Ray’s frameworks, may be activated by ragas like Bhimpalasi, known for their emotive qualities [3]. However, Ray’s model associates specific brain regions, such as the anterior cingulate cortex, with these chakras, proposing that their activation enhances functional connectivity [3]. Preliminary studies suggest that music-based interventions targeting specific frequencies can modulate brain activity [2].
For instance, low-frequency sounds (e.g., $100–200$ Hz) associated with the root brain chakra increase $\delta$ band power, promoting relaxation. Higher-frequency sounds (e.g., $400–600$ Hz) linked to the Vishuddha brain chakra may enhance $\beta$ band activity, supporting communication and creativity. These effects may be amplified by improved brain fluid dynamics, as vibrational frequencies could enhance CSF and CBF, supporting neural health [4]. ICM’s microtonal precision and raga-specific emotional profiles offer a natural platform to test these hypotheses, bridging traditional wisdom with scientific inquiry.
Therapeutic Potential and Future Directions
The neurodynamic effects of ICM suggest significant therapeutic potential, particularly for neurological and psychiatric disorders. Music therapy studies indicate that rhythmic auditory stimulation, akin to ICM’s tala, improves motor coordination in stroke patients [3]. The emotional resonance of ragas may alleviate symptoms of anxiety and depression, potentially through limbic system modulation [1]. Chanting-based interventions, aligned with the Sri Amit Ray Brain Chakras framework, could enhance mindfulness and stress resilience, offering a complementary approach to cognitive-behavioral therapy [3, 2]. Additionally, the potential influence of ICM on brain fluid dynamics, such as enhancing glymphatic clearance, may reduce neuroinflammation and support recovery in neurodegenerative conditions [4].
Future research should map the spatiotemporal dynamics of ICM processing, focusing on how formulaic patterns influence neural connectivity. Multimodal neuroimaging (e.g., fMRI, EEG) combined with computational models, such as gammatone-based auditory processing frameworks, could simulate ICM’s impact on the auditory cortex [1]. Studies targeting the Sri Amit Ray Brain Chakras could explore how specific frequencies modulate neural hubs [3], while computational models of brain fluid dynamics could elucidate how ICM affects CSF, ISF, and CBF [4]. Cross-cultural studies comparing ICM with other musical traditions would clarify its unique neurocognitive effects. Additionally, randomized controlled trials are needed to evaluate the efficacy of ICM-based interventions, particularly those incorporating Ray’s brain chakra framework and brain fluid dynamics, leveraging recent insights into musical neurodynamics [3, 2, 4].
Conclusion
Indian classical music, with its Pallavi–Anupallavi–Charanam structure and formulaic patterns, offers a rich auditory stimulus that engages complex neurocognitive processes. By integrating ancient chanting practices, the Sri Amit Ray's 28 Brain Chakras framework, which extends beyond the traditional seven chakras to include specialized neural energy centers, and computational models of brain fluid dynamics, this article proposes that ICM modulates auditory processing, emotional regulation, neural oscillatory networks, and brain homeostasis. These insights, supported by recent neurodynamic research, highlight ICM’s potential as a therapeutic tool and underscore the value of interdisciplinary approaches in neuroscience [2, 4]. As we unravel the neurodynamics of this ancient art form, we pave the way for innovative interventions that harmonize mind, body, and spirit.
