In this play, Donatelli arranged a contrasting background, one is a free military camp where simple soldiers gather, and the other is an antique but uncomfortable castle where elegant aristocrats live. At the same time, he successfully combined difficult music with kind songs. Because most of them are written in major, the whole play feels quite bright and beautiful. The magnificent March in the play is very effective and can easily arouse the patriotism of the audience.

During World War II, metropolitan opera inserted military songs or national anthems into plays to boost morale. Hempel and Lily Pang Sai sang Maria on the stage successively.

From 65438 to 0972, in metropolitan opera, Pavarotti sang nine high-pitched C's that resonated with the chest for the first time in Girl in the Army, which was performed with Australian soprano Sutherland, and was called "the king of high-pitched C's" from then on.
