Pronunciation: [ɑː jˈuːnɪsən] (IPA) 
The phrase "are unison" is pronounced /ɑr junɪsən/. It consists of the verb "are" and the noun "unison." "Are" is spelled with an "a" and an "e" because it is a vowel digraph. "Unison" is spelled with a "u" because it is pronounced with a rounded vowel sound. The word "unison" comes from the Latin words "uni," meaning one, and "sonus," meaning sound. Together, they form a word that means being in complete agreement or harmony.
The phrase "are in unison" refers to a state or action in which multiple individuals or entities are coordinated and acting together in complete agreement or harmony. Unison can imply a shared understanding, consensus, or synchrony among all involved parties. It is often used to describe a situation where people or things are working in tandem, united, or aligned towards a common goal.
In music, unison signifies when multiple voices or instruments produce the same tone or pitch simultaneously. This is achieved by playing or singing the exact same musical notes, creating a harmonious and cohesive sound. Similarly, in other contexts, being in unison suggests a collective effort, shared opinion, or a unified act performed by diverse individuals. It implies that these individuals are conveying the same message, sharing a common purpose, or demonstrating consistent behavior.
Being in unison often connotes efficiency, effectiveness, and solidarity. It implies a relationship that transcends mere agreement, highlighting a sense of cohesion and teamwork. In this state, the distinct voices or entities blend together, echoing a single sentiment or taking synchronized action. Whether it be in music, conversation, decision-making, or collective action, being in unison demonstrates a seamless unity that facilitates progress, understanding, and success.
The phrase "are unison" does not have an established etymology because it is a combination of two unrelated words.
The word "are" is the second person singular and plural form of the verb "to be" in the present tense. Its etymology traces back to Old English and Old Norse, and it has remained relatively consistent throughout the history of the English language.
The word "unison" originates from the Latin word "unisonus", which translates to "having one sound". It entered the English language in the early 18th century, primarily referring to musical terminology, representing the playing or singing of notes at the same pitch or in octaves. The word has since been extended to describe any simultaneous or identical action or occurrence.
