Thank you to Rob Deemer for his post on NewMusicBox listing 202 living women composers! The list includes links to the composers’ websites as well. Make sure to also take a look at the comment section for ongoing contributions by others of additional women composers. Perhaps you will have someone to add as well?
also, if you don’t know of her, check out influential electronic composer Suzanne Ciani:
