Since 5 princesses were originally commoners, what you're going to read is actually a few coronation music that will suit when the these 5 commoners became princesses!

1. Royal Coronation Overture (Patrick Brill)

So the composer is modern, but this music sounds French and Baroque. I personally think that Belle and Cinderella will use this music since they are French.

2. Marche de Triomphe (Marc-Antoine Charpentier)

Another French Coronation, only this time by a French composer! Considering that this piece was use for the coronation of King Louis XIV of France (AKA The Sun King), it sounds pretty wonderful and for 5 princesses to march to this music!

3. Zadok the Priest (George Frederick Handel)

This music is for the coronation of every British monarchies, it would something different because it doesn't sound French at all!

4. I Was Glad (Hubert Parry)

This song was used in the 2011 Royal Wedding of Will and Kate, when the latter was walking down the aisle. It sounds Majestic and Grand for every princess to walk!

A Royal Coronation

Considering that Mulan is the only one who is from the Orients, I bet she should be very adventurous on the behalf of her other Disney Princess friends! If you have anymore suggestions, leave it in the comment box.
