After the reciting tone, every mode is distinguished by scale degrees called "mediant" and "participant". The term "mediant" also refers to a relationship of musical keys. Mediant tonicization in major is an important feature of Romantic music. The mediant is named from its position between the final and reciting tone. The first section of this is noteworthy for ending on unusual cadence on the mediant.
