The present progressive tense (also sometimes called the "present continuous") is formed with the present tense of the verb to be + a main verb + -ing, as in, "He is constantly calling me," or, "The neighbors are playing their music really loudly."
We use the present progressive tense to 1) describe an action that’s continually repeated, or 2) talk about an on-going action that’s happening right now.
Words like "always," "constantly," or "continuously" are often used with the present progressive to describe actions that are repeated, while phrases like "right now" or "at the moment" often indicate that an action is currently in progress.
