The Digital Resurrection of the Shusha School: Using AI to Reconstruct the Lost Microtonal Nuances of 19th-Century Mugham Vocalists
How are we restoring the lost vocal nuances of the Shusha Mugham school using AI? Discover the digital reconstruction of 19th-century microtonal secrets.

The Musical Crown of Karabakh: The Shusha School
For centuries, Shusha—hailed as the 'Conservatory of the Caucasus'—has been the beating heart of Azerbaijani Mugham. In the 19th century, the voices of maestros like Jabbar Garyagdioglu and Khan Shusha echoed through these mountains. However, the recording technologies of that era, such as old gramophone records and wax cylinders, failed to capture the essence of Mugham: the intricate microtonal nuances and the singers' 'zangula' (ornamentations).
AI and the Restoration of the 'Golden Fund'
Today, at PromptAZ Music, we are utilizing Artificial Intelligence (AI) algorithms to breathe new life into the scratchy, degraded recordings found in the 'Golden Fund' archives. AI separates the vibrations of the 11-stringed Tar and the soulful wail of the Kamancha from background noise, reconstructing the performer's original breathing and vocal techniques.
The Emotional Spectrum of Mugham Modes
In the restoration process, the philosophical weight of each Mugham mode is meticulously preserved:
- Rast: Restoring the cheerful and vigorous spirit.
- Shur: Clarifying lyrical and mystical transitions.
- Segah: Emphasizing romantic and love-filled ornaments.
- Chahargah: Enhancing heroic and majestic resonance.
- Bayati-Shiraz: Refining melancholic and soulful tones.
- Humayun: Tracing deep philosophical reflections digitally.
- Shushtar: Purifying mournful and profound emotions.
This technology does not merely clean the audio; it reconstructs lost frequencies through mathematical modeling. Consequently, the velvety sound of the Balaban and the rhythmic precision of the Gaval bridge the gap between the 19th-century soul and the 21st-century listener.
