Summary

The Hidden Voices of Women Composers

Gabriella Di Laccio's journey begins with a discovery in a London second-hand book market — an encyclopedia listing 6,000 women composers, most of whom she had never heard of. This revelation sparked her mission to uncover and document more than 18,000 women composers whose contributions to music had been historically overlooked or lost. She emphasizes that despite her training as a professional musician, she was unaware of most of these women’s work, highlighting a significant gap in musical history. Her efforts to catalog and share these voices aim to correct this imbalance and ensure their stories and compositions are preserved and celebrated.

The Impact of Bias in Music and AI

The episode discusses how the music we listen to is overwhelmingly composed by men—nearly 90%—which means a vast amount of women’s creative work has been excluded from mainstream exposure. This imbalance extends into AI-generated music, which is trained on existing data that is similarly skewed, consequently perpetuating the silence of half of humanity’s artistic voice. Gabriella advocates for recording and sharing underrepresented and missing voices—not only as a moral imperative but also to enrich the musical landscape and ensure AI models learn from a more complete, diverse set of data.

The Power of Recording and Representation

Gabriella urges the community—tech companies, musicians, and listeners—to invest in recording and making accessible the music of historically marginalized groups, especially women. By doing so, these recordings can be integrated into educational platforms, radio, streaming services, and AI models, making these works more searchable, teachable, and part of the future musical canon. She stresses that choices about what is heard and remembered are in our hands, and that inclusion directly influences cultural memory.

A Personal and Historical Story of Resilience

The episode concludes with the story of Ilze Weber, a poet and singer imprisoned during WWII who wrote songs to uplift and entertain fellow prisoners. Despite her tragic death in Auschwitz, her manuscripts were buried and survived, exemplifying how individual acts of creativity can endure against all odds. Gabriella emphasizes the importance of teaching AI to remember diverse voices, including those who faced tremendous hardship, to preserve the full spectrum of human expression.

Show notes

Who decides which voices survive? It's a question classical singer Gabriella Di Laccio never thought to ask until she found an encyclopedia listing thousands of women composers from across history ... and knew almost none of them. Her journey to rediscover these brilliant musicians revealed how many songs have gone unheard — and sparked a mission to record what's missing before the silence becomes permanent.
