Music by Women
Music by Women is a database of music theory examples by women composers in history from antiquity to the present. It’s well organized with a filtering system, so you can find any example you need to learn or teach a music theory concept.
In addition to its large database of music theory examples, the site also features women composer and music theorist biographies, their own scholarly journal, and gorgeous posters featuring these women composers and theorists.
Their mission is “to elevate women composers and theorists by advocating for the study and performance of their works and providing high-quality easily-accessible resources that bring light to the often overshadowed contributions of women in music.”
