The Rebirth of 'Nuzha' and 'Chagan': Reviving the Timbre of Azerbaijan’s Forgotten Medieval Instruments through AI

Invisible Pages of Our Musical History

Azerbaijani musical culture consists of far more than the sounds of the Tar, Kamancha, and Balaban we hear today. Our 'Golden Fund' contains magnificent instruments that have been silent for centuries but were once the jewels of royal courts. Today, at the intersection of technology and history, we discuss the reconstruction of the 'Nuzha,' a legacy of the great musicologist Safiaddin Urmavi, and the 'Chagan,' the echo of Nizami Ganjavi’s era.

The Synthesis of Archaeological Data and AI

Reviving forgotten instruments is not just about physical form; the real challenge lies in rediscovering their unique timbre. Modern musicology utilizes AI algorithms to perform the following:

  • Acoustic Modeling: Data on wood types and string materials from medieval treatises (such as those by Abdulgadir Maraghai) are analyzed by AI.
  • Timbre Simulation: The resonance frequencies created by the Nuzha’s 81 strings are reconstructed in a digital environment.
  • Mugham Compatibility: Testing how these instruments respond to the romance of Segah or the melancholy of Bayati-Shiraz.

Nuzha and Chagan: From Sound to the Depths of the Soul

The Nuzha, invented by Safiaddin Urmavi, was a symbol of the Eastern Renaissance with its harp-like structure. Its wide range is capable of delivering the cheerful spirit of the Rast mugham and the heroic echoes of Chahargah with equal perfection. On the other hand, the Chagan, a bowed instrument, is considered an ancestor of the Kamancha, and its touching, lyrical voice is indispensable for the Shur mugham.

A Vision for the Future: The Digital Legacy of the Golden Fund

These reconstruction projects are not merely a return to the past; they are about shaping the musical language of the future. These sounds, restored via AI, become a new source of inspiration for young composers. At PromptAZ Music, we consider it a moral duty to preserve these rare gems of our national identity and integrate them into the musical treasury of the digital age.
