I’m not sure if she’s interested in this route, but my sister has a BA in music performance, and got a masters in elementary education, so she is certified to also be a classroom teacher. However, she has taught music at the elementary level (pre-kids) and middle school level (after kids grew). I believe the thinking was that if they cut music, she would still be eligible to have a job.
Also note that in this area of VA, most specials are full time teachers paid at the same levels as classroom teachers. (Elementary Art in H’s district is the only exception I know of)
