One of the powerful things about the musical, Wicked belongs to the songs alone. It even has the kind of score that I look for- the combo of positive and negative emotions. It has the heartbreaking “I’m Not That Girl” (which started out as no more than a sad song) and the bittersweet “For Good” Those are the two songs that made me realize sad was a musical theatre emotion. So, what of those two is exactly the MOST emotional?
I’m Not That Girl- possible spoilers
Well, from just glance, you would think this is the most emotional. I’m Not That Girl is an unrequited love song- true, it is a heartbreaking love song, but also ironic. Little does Elphaba know that she will get Fiyero in the end- the irony behind I’m Not That Girl. It is true——I had originally thought the song was sad (not heartbreaking)- but I knew the song was deepening. I had to discover the emotion, heartbreak first, and another song had to help it (as in a stronger and more powerful unrequited love song). It was On My Own that finally made me realize I’m Not That Girl was an unrequited love song, and memorizing the lyrics saw me see even more insight in the song

For Good
This is the more emotional song in Wicked. Yes, it is a bittersweet song—–a powerful one that centers on our two protagonists. Elphaba and Glinda have a powerful and beautiful friendship- they even wouldn’t let a boy get in the way. The most important person in their lives belongs to each other- Glinda was Elphaba’s only friend and Elphaba was the only friend that truly mattered in Glinda’s life.

The center core of Wicked is between Glinda and Elphaba- their friendship. That is why For Good is the most emotional song in the show- the last moment the two friends will see each other, and are able to say that they mattered to each other
