Music Theory

MIDI numbers treat D♯ and E♭ as identical, yet in music theory they are not the same note. This fundamental ambiguity undermines symbolic reasoning for interval spelling, chord spelling, and key transposition. Discover a formal specification written in Z notation that resolves the problem, and see how classic constructs—interval qualities, chord inversion, doubled notes—can be embedded into a computational knowledge base exactly as a trained musician would understand them.

A dozen recent releases capture the sophisticated world of fourteenth-century music far beyond tales of taverns and church chant. From the intricate motets and ars subtilior of the Codex Chantilly to the numerically coded rondeaux of Guillaume de Machaut, these performances draw on new scholarly editions and careful instrument pairings to reveal both the sacred and secular dimensions of European music between 1300 and 1400. CD reviews include Machaut by the Orlando Consort, dramatic staging of t

What if Bach's fugues and your violin's tone share the same hidden blueprint? Since the 1990s, scientists have known that musical compositions from Mozart to modern styles show fractal geometry — patterns that repeat at different scales. Now, measuring the fractal dimension of individual instruments like the flute, sitar, and tampura reveals a fascinating spectrum between order and randomness. Here is how to compute these values using nothing more than a one-second audio clip, a bit of Matlab, a

Breakcore redefines musical value by repurposing nearly-outdated pop hits as sonic detritus, all distributed for free on netlabels. This niche electronic genre leverages trash aesthetics, sampling, and irony to challenge what music is worth — economically, culturally, and aesthetically. Learn how producers exploit the slippage between price and value in online music ecosystems.

For Hegel, art isn't just decoration—it's a pathway to grasping the infinite. Music especially gives form to our experience of being-in-time, pitting freedom against necessity in a manner only sound can convey. This article unpacks how Hegel positioned music as the art that most directly mirrors the inner life of a self-conscious agent—one whose awareness of temporality, and the fork-by-fork decisions shaping existence, finds its most faithful expression in structured sound.

Philadelphia has always been a noisy, musical place. This college seminar takes you on a journey through the area’s musical heritage — from the songs of the Delaware people to the soul of Gamble and Huff, the rise of hip hop with Schoolly D and the Roots, and beyond. Through regular field trips, archival research at Penn’s libraries, and performances across the city, you will learn to decode what you hear and uncover hidden musical gems. No prior music knowledge is needed, only curiosity and a w

For over 40 years, one Greek radio show proved that a DJ can be more than a voice between records. Yannis Petridis built a music narrative that educates, contextualizes, and connects songs — turning airtime into genuine music journalism. This analysis decodes the radio language he mastered, blending conversation analysis and sound semiotics to reveal how DJs shape musical meaning.

Sound once served only as a carrier for melody and harmony — a transparent medium secondary to musical structure. Today it sits at the center of composition, from electroacoustic works to studio-produced pop and immersive sound installations. Modern audio culture has transformed how musicians, composers, and listeners engage with sonic substance. This history traces the revolutionary shift from a note-based musical tradition to one fully centred on sound — comparable in scope to the birth of ton

Medical procedures are almost universally associated with anxiety, placing strain on patients, caregivers, and healthcare professionals alike. Music therapy offers a cost-effective, evidence-based solution that works across the full care cycle—reducing pre-procedural fear, distracting conscious patients mid-procedure, and easing pain perception in recovery. From root canals with live instruments to pediatric immunisations using playful rattles, discover how professional music therapists tailor t

"I cannot believe that God plays dice." Emerging from his profound critique of quantum theory's foundations, the EPR paradox forced us to rethink knowledge, reality, and locality. Yet hidden inside this "incomplete theory" is something else: a strange, deeply structural logic connecting Einstein’s world of information collapse to the semantic structure underlying music itself. Could quantum formalism reveal the innermost patterns of musical expression?
