“The heavenly bodies are nothing but a continuous song for several voices.” – Johannes Kepler

Johannes Kepler, best known for his revolutionary work in astronomy, also developed a distinctive philosophy of music that bridged mathematics, cosmology, and spiritual symbolism. His most significant contribution on this topic is found in his work Harmonices Mundi (“The Harmony of the World”), published in 1619. This text explores the interconnectedness of geometry, astronomy, and music, revealing how Kepler perceived music as a cosmic principle rather than merely a human art.

Kepler built on the ancient concept of the “music of the spheres,” which posits that the planets and their motions create a form of music—a harmonious, mathematical order underlying the cosmos. He argued that the ratios governing planetary orbits correspond to musical intervals, meaning the universe itself is structured by the same laws that produce musical harmony. For Kepler, this was neither metaphorical nor poetic but a literal and mathematically demonstrable truth.

He saw music as an audible manifestation of the geometric and arithmetical relationships that organize both the cosmos and the human soul. Drawing on Pythagorean tradition, Kepler believed that these mathematical harmonies had a spiritual dimension, connecting the physical with the divine. Music, in this sense, was not merely aesthetic but ontological—a reflection of the order and rationality of creation itself.

Kepler’s philosophy implied that understanding music’s mathematical foundations could bring a person closer to comprehending the mind of God, since the same harmonious principles operated at every level of existence. He connected this with an ethical dimension: just as harmony brings order to the universe, so seeking harmony in life aligns one with the cosmic order.

“The mind exists so long as there is sound” – Nadabindu Upanishad

Nada Brahman is a profound concept rooted in the spiritual and philosophical traditions of India, especially within Hinduism and certain schools of Yoga. The term itself is composed of two Sanskrit words: “Nada”, meaning sound or vibration, and “Brahman”, denoting the absolute, ultimate reality or cosmic consciousness. When combined, Nada Brahman refers to the understanding that the fundamental, all-pervading reality, the very foundation of existence is, of the nature of sound or vibration.

From this perspective, sound is not merely a sensory experience but the primal creative force behind manifestation. According to the ancient Upanishads and the teachings of several mystical traditions, everything in the universe is in a state of vibration. The unstruck, eternal sound—Anahata Nada—is said to be the substratum from which all forms and phenomena arise. This is not ordinary audible sound, but a subtle, inner resonance that forms the bridge between the manifest and the unmanifest. Nada Brahman thus represents the realization that the cosmos itself is an expression of divine vibration, and that by tuning into this inner sound, one can access deeper layers of consciousness and ultimately the absolute.

In the practice of Nada Yoga, for example, practitioners cultivate inner listening to discover this sacred sound within themselves. This is not just a meditative technique but a metaphysical pathway, pointing to the unity between the self and the ultimate. The process invites the seeker to move from gross, external sound (ahata nada) towards the subtle, inner resonance (anahata nada), eventually dissolving the boundaries of ego and merging with the infinite. In this way, Nada Brahman becomes both a metaphysical principle and a practical guidance for spiritual realization: it teaches that by attuning ourselves to the primordial sound within, we remember our inherent connection to the absolute consciousness.

“Physical matter is music solidified.” – Pythagoras

Pythagoras’s philosophy of music is rooted in a profound synthesis of mathematics, cosmology, and spiritual practice. Living in 6th century BCE Greece, Pythagoras and his followers viewed music not merely as an art form, but as a key to understanding the hidden order of the universe. They saw musical harmony as a direct reflection of cosmic harmony, an audible manifestation of the same mathematical ratios that structure reality itself.

At the heart of Pythagorean musical philosophy is the insight that the cosmos is fundamentally mathematical, and that harmony in music mirrors the “Music of the Spheres” or “Musica Universalis”, the belief that the planets and stars move according to mathematical equations, producing a kind of celestial music inaudible to human ears but perceivable by the soul.

For Pythagoras, music was also instrumental in cultivating the soul. He believed that certain modes and rhythms could directly influence the soul’s disposition and even bring the body and mind into alignment. Music was used therapeutically, to purify the emotions or “tune” the soul, a practice that became known as musica humana. This was not a metaphorical stance; the Pythagoreans regarded these correspondences as operating according to strict natural law, linking the microcosm (the human being) and the macrocosm (the universe).

This philosophy situates music at a crossroads of the ethical, mathematical, and spiritual. The ethical element appears in the belief that proper musical practice leads to inner harmony and moral character. The mathematical aspect emerges in the investigation of ratios, which for Pythagoras, are archetypal forms underlying both music and nature. Spiritually, music becomes a path to self-knowledge and cosmic attunement, a means to participate in the order and beauty of the universe.

“When someone lives in the experience of music, he is living in the image of his spiritual home” -Rudolf Steiner

Rudolf Steiner taught that music, in its essence, arises from realms beyond the material world. He viewed tone as a spiritual reality, not simply a physical vibration. According to Steiner, the intervals, rhythms, and harmonies we experience are echoes or reflections of cosmic processes. For him, melody corresponds to the soul’s journey, harmony speaks to the relationships between spiritual beings, and rhythm connects the earthly human with the cosmic order. In this sense, music is both a mirror and a bridge, revealing the structure of higher worlds while transforming the listener’s inner life.

A critical concept in Steiner’s music philosophy is the idea that different musical modes and intervals have specific spiritual effects. He argued that ancient and folk musical forms often held a wisdom lost to the rationalism of Western classical music. Steiner was particularly interested in the evolution of consciousness as expressed through musical history; he saw the move from ancient modal music to the development of polyphony and harmonic complexity as paralleling humanity’s changing relationship to spirit and self-awareness.

Another important aspect is Steiner’s assertion that musical experience shapes both the soul and the body. For instance, he believed that certain musical approaches enhance spiritual clarity and health, while others can be disintegrative. This belief led to his support for therapeutic music practices, including his collaboration with composer Maria Röschl and the development of the discipline now called “anthroposophic music therapy.”

Steiner also placed music within the context of his teachings on eurythmy, a movement art he developed, which aims to make music and speech visible through gesture. He believed that sound, movement, and consciousness are inseparable, and that engaging with music through eurythmy can harmonize the individual’s physical, etheric, and astral bodies.

It’s important to recognize that Steiner’s philosophy of music is inseparable from his broader worldview. For those who approach music as a vehicle for self-knowledge and transformation, Steiner’s work offers a framework in which musical practice becomes a spiritual discipline—one that can both reveal and cultivate the inner architecture of the human being.

Rudolf Steiner (1861–1925) was an Austrian philosopher, esotericist, educator, and spiritual scientist whose work laid the foundation for the modern movement known as Anthroposophy. His intellectual journey began in the context of late 19th century Central European culture, marked by both scientific rigor and a search for spiritual meaning beyond materialism.

Steiner studied natural sciences, mathematics, and philosophy at the Technical University of Vienna and was profoundly influenced by Johann Wolfgang von Goethe’s scientific writings, which sought to bridge the split between objective observation and subjective experience. Early in his career, Steiner edited Goethe’s scientific works and developed a method he called “spiritual science,” which aimed to unite rational inquiry with direct spiritual perception.

Through lectures and writings, Steiner developed a comprehensive spiritual cosmology. He described a multidimensional human being composed of physical, etheric, astral, and ego bodies, and taught that human evolution is both a spiritual and a material process. His teachings encompass reincarnation, karma, and the transformative potential of self-awareness.

Steiner’s legacy extends into practical initiatives. He founded the Waldorf education movement, which seeks to nurture the whole child—body, soul, and spirit—in harmony with developmental laws. He also initiated biodynamic agriculture, a holistic approach to farming that regards the farm as a living organism, also contributing to architecture, medicine, and the renewal of Christian esotericism. Steiner was a teacher of synthesis, integrating spiritual insight with practical life.

“There is the music of Heaven in all things” – Saint Hildegard von Bingen

Composer Hildegard von Bingen is one of the most influential figures in Western esotericism and Christian mysticism. Her philosophy of music is deeply intertwined with her theological, cosmological, and visionary worldview. For Hildegard, music was more than a form of entertainment, it is a means for realigning the soul with the harmony of the cosmos and the will of the Divine.

Hildegard viewed music as an echo of the celestial harmonies, what she called the symphonia of creation. In her writings, particularly in her Scivias and the prefaces to her musical compositions, she articulates that music is embedded in the very fabric of existence. She believed that the soul, before entering the body, participates in a choir of angels, singing in perfect unity. Incarnation creates a sense of separation from this original harmony, but music serves as a bridge, reconnecting the soul to its divine source, aligning more closely with the eternal harmony of the Creator.

Her compositions are marked by soaring melodies that break from the conventions of her time, reflecting her belief that music should strive to express the spiritual realities glimpsed in her visions. For Hildegard, singing was an act of praise that had the power to heal, purify, and restore order, both in the individual soul and in the communal body of the church. She emphasized that music has a therapeutic aspect, capable of realigning the microcosm of the human with the macrocosm of creation—a core tenet of her holistic, esoteric philosophy.

Hildegard’s understanding of music also carries a dual dimension: it is both an offering to God and a means by which the human community sanctifies itself. In her view, neglecting music or distorting its sacred purpose was a sign of spiritual disorder, while full-hearted musical praise was a sign of alignment with divine wisdom (Sapientia). This reflects her broader approach—seeing the material and sensory world not as a distraction from spirit, but as a medium through which divine realities are enacted and embodied.

Hildegard von Bingen was a German Benedictine abbess, visionary, composer, writer, healer, and one of the most influential mystics of the 12th century. Born in 1098 in Bermersheim (now in modern day Germany), she entered monastic life at a young age and eventually founded her own independent abbey on the Rupertsberg near Bingen.

Her visionary experiences began in early childhood and continued throughout her life, which she told no one. Until her 40s when she was directed by one of her visions to write down her experiences, becoming the foundation for her major works of theology and cosmology, such as Scivias (“Know the Ways”), Liber Divinorum Operum (“Book of Divine Works”), and Liber Vitae Meritorum (“Book of the Rewards of Life”). These writings are distinctive for their vivid imagery, presenting a cosmos suffused with divine energy and order.

Hildegard was also a prolific composer; her surviving musical works include over seventy liturgical songs and the morality play Ordo Virtutum (“Order of the Virtues”), which is considered one of the earliest known musical dramas. Her music stands out for its melodic daring and spiritual intensity, reflecting her belief that music was a means of connecting with the divine.

In addition to her theological and musical output, Hildegard wrote extensively on natural history, medicine, and healing, drawing from both observation and visionary insight. Her medical works, such as Physica and Causae et Curae, blend folk wisdom, herbal remedies, and spiritual principles, all grounded in her concept of viriditas, the life force permeating all creation.

Hildegard’s influence was recognized in her own lifetime; she corresponded with popes, emperors, and other notable figures, and was regarded as a spiritual authority. She was canonized as a saint and, in 2012, named a Doctor of the Church, acknowledging her theological contributions. Her life and legacy continue to inspire those interested in mysticism, holistic health, art, and the integration of spiritual and material realities through the celestial harmonies of music.

“Music is the answer to the mystery of life.” – Arthur Schopenhauer


Arthur Schopenhauer (1788–1860) was a German philosopher whose work occupies a pivotal position in the history of Western thought. He is widely recognized for his central concept of the “Will”—an unconscious force he saw as the true essence behind all phenomena. Schopenhauer’s primary philosophical work, The World as Will and Representation, articulated his worldview: while we usually experience life as a series of representations (appearances in our mind), the underlying reality is a striving Will that animates all forms of existence.

Schopenhauer regarded music as the highest and most profound of the arts, assigning it a unique metaphysical status in his philosophical system. For Schopenhauer, all artistic forms represent the world of phenomena—they are imitative, giving form to the Platonic Ideas that underlie the objects and experiences of everyday life. However, music stands apart. Rather than representing mere appearances, Schopenhauer argued that music is a direct expression of the underlying reality he called the Will.

While the visual and literary arts reflect the shapes and stories of the world as manifestations of Will, music bypasses these representations entirely. It articulates, in abstract sonic form, the inner movements and patterns of the Will itself. This is why, Schopenhauer claims, music has such direct emotional power: it does not represent individual emotions or events but instead communicates the universal essence that lies at the root of all experience.

This idea leads him to suggest that music is not an imitation of the world, but rather the world itself is in a sense an embodiment of music. Melodies, rhythms, and harmonies correspond to various modes and gradations of the Will’s striving, from the simplest drives to the most complex passions. Therefore, musical understanding is a kind of intuitive metaphysical insight—listening to music enables us to apprehend the innermost nature of existence without the mediation of concepts or images. Schopenhauer’s emphasis on music’s metaphysical immediacy, and its capacity to reveal the depths of the human condition, continues to inform contemporary discussions about the unique power and mystery of musical experience.

mysticism of music…the teachings of Hazrat Inayat Khan – Part 1

Hazrat Inayat Khan, a foundational figure in the transmission of Sufism to the West during the early twentieth century, expounded a philosophy in which music holds a central place not just as art, but as a spiritual practice and a metaphysical principle. For Khan, music is far more than organized sound; it is a universal language and a means for developing spiritual consciousness.

Khan taught that the entire universe is ultimately composed of vibration, and music is the most accessible and refined expression of this primordial reality. He saw music as the bridge between the finite and the infinite, capable of tuning the soul to higher states of awareness. The mysticism of music, in his understanding, involves perceiving the underlying unity and harmony that music both reflects and awakens within the individual. When attuned to music with sensitivity and presence, the listener is able to access subtle states of insight, peace, and connection with the divine.

For Khan, all religions and mystical traditions can be seen as expressions of the same music—the music of divine harmony manifested in different cultural forms. Musical practice becomes a vehicle for self-transcendence, enabling the seeker to experience directly the spiritual truth that lies beyond conceptual knowledge. Thus, music is not merely an ornament of spiritual life, but a profound practice—one that refines the heart, harmonizes the mind, and prepares the soul for union with the source of all being.

He was born in Baroda, India, (July 5 1882) into a family with a strong musical and spiritual heritage. From an early age, he studied classical Indian music and became an acclaimed musician, specializing in the vina, a traditional string instrument.

Khan was formally initiated into the Chishti Sufi Order, one of the major mystical schools of Islam, which emphasizes love, tolerance, and openness. He would later receive initiations in the Qadiri, Suhrawardi, and Naqshbandi Sufi orders as well, integrating these lineages into his teaching.

In 1910, he left India at the instruction of his Sufi teacher, carrying with him the mission to spread the message of spiritual unity to the West. He first traveled to the United States, and then to Europe, where he began teaching, performing music, and attracting students from many backgrounds.

His approach to Sufism was universalist, focusing on the essence of mystical experience rather than the dogmas of any single religion. He established the Sufi Order in the West—now known as the Inayatiyya—which continues to transmit his teachings worldwide.

Among his key contributions was the integration of music and mysticism. He articulated a detailed philosophy about the spiritual power of music, seeing sound and vibration as fundamental to all existence.

He wrote extensively, leaving behind a substantial body of lectures, poems, and books. Works like “The Mysticism of Sound and Music” remain central texts for those interested in the spiritual dimensions of music.

Hazrat Inayat Khan died in Delhi in 1927, but his legacy endures through the global Sufi movement he founded and the continuing influence of his writings on both Sufi and non-Sufi spiritual circles. His teachings remain vital for anyone seeking a synthesis of inner awakening, art, and universal spiritual values.

Is the universe made of Music?

The notion that God or the universe is “musical” speaks to an ancient intuition: that existence is governed by patterns, vibration, and harmonious relationships—much like music itself.

In the Western esoteric tradition, this principle is reflected in the concept of the “music of the spheres,” articulated by Pythagoras and later echoed by Plato and early Christian mystics. They envisioned the cosmos as a vast, harmonious system wherein each planet and star emits a unique tone, creating a divine symphony. Here, music becomes a metaphor for the ordered, mathematical relationships underlying the manifest world. This idea permeates the Kabbalah as well, where the creative utterance (“Let there be light”) is not just speech, but vibration—an act of resonance that brings forth being from non-being.

Hindu philosophy, especially in the concept of Nada Brahma (“the world is sound” or “God is sound”), presents the universe as fundamentally vibrational. The primordial sound Om is said to be the source from which all creation unfolds, and the universe itself is continuously being woven through subtle sound—again, a musical process. This tradition suggests that by attuning one’s inner ear to these vibrations, a person may come closer to union with the divine.

From a psychological perspective, Jung might have argued that the musical metaphor represents the psyche’s drive for inner harmony—a dynamic balancing of opposites, like the interplay of consonance and dissonance in music. Music captures the way human beings experience meaning: not as static facts, but as dynamic, evolving patterns that can provoke awe, sorrow, joy, or even transcendence.

Modern physics, too, has explored this intuition. String theory, for example, posits that the fundamental constituents of reality are not particles, but vibrating strings whose different modes correspond to different particles—suggesting that, at its most basic level, the universe may literally be a kind of cosmic music.
