Summary

Research by Alberto Messina, Lorenzo Canale, and Stefano Scotta investigates semantic homogenization in Italian popular music lyrics, mirroring a trend observed in English-language songs. Their study analyzes the lyrics of all finalist songs from the 75 editions of Italy's Sanremo Music Festival. The authors developed a flexible methodology to track changes in semantic similarity over time, employing full-text, segment-based, topic-based, and word-level analyses, which integrates both embedding techniques and large language models. Applying this framework to the Sanremo corpus revealed a gradual increase in semantic uniformity, consistent with global patterns. These findings emphasize the effectiveness of natural language processing tools in identifying long-term shifts in musical language and broader cultural expression.

Key takeaway

For NLP Engineers or cultural researchers analyzing linguistic evolution in media, this work offers a robust, adaptable methodology to detect semantic homogenization. You should consider applying this multi-faceted framework, which combines embedding techniques and large language models, to track evolving semantic landscapes in other cultural corpora. This approach provides a powerful lens for diachronic linguistic analysis, enabling the identification of subtle shifts in expression and cultural trends over time.

Key insights

Italian popular music lyrics, like English ones, show increasing semantic uniformity over 75 years.

Principles

• Semantic variety in popular music declines diachronically.
• NLP tools reveal long-term cultural shifts.

Method

A methodology combines full-text, segment-based, topic-based, and word-level analyses using embeddings and large language models to track semantic similarity changes.

In practice

• Apply methodology to other linguistic contexts.
• Analyze cultural trends via lyrical semantics.
