Ingeborg Von Bronsart (1840-1913) Finland

Composer and pianist, she wrote opera, chamber music, piano works, numerous songs, and a lost piano concerto. Here's her Phantasie Op. 21 for violin and piano; here's a link to download the score.

During her lifetime, her operas were successfully produced in many German theaters. I'm sharing a video of the overture and a link to the full score of Jery und Bätely, a one-act opera whose librettist was Goethe.

Most of her works were songs. Next up is Zuleicha, the first of Mirza-Schaffy's 6 Lieder, Op. 8. The link to download the score includes the rest of the songs.
