tonal

adj

2. Of or relating to the general character, mood, or trend of something.

   “The lurid way the story played out felt like a tonal shift for Empire, but not necessarily a bad one—in the process of shedding its cool costume-drama attitude for grotesque family dysfunction, the episode felt for once less like a story about Prohibition and more one about a specific set of people.”

3. Employing tones that have a predictable relationship to some tonic.
4. Employing differences in pitch (tones) to distinguish differences in the meaning of otherwise similar words (words which would otherwise be homophonic).
