Share Apple music wih my wife

Can I share my Apple Music subscription with my wife. I currently pay 9.99 a month and she was paying 9.99 a month but we would like to share one Apple Music subscription. Please let me know if we are double paying or if we must buy two different Apple Music subscription. Thanks!

I appreciate any feedback you might have because we don't wanna pay more than is necessary to listen to music. Thank you
