Blow your own trumpet and toot your own horn are two expressions of the same idiom. An idiom is a word, group of words or phrase that has a figurative meaning that is not easily deduced from its literal meaning. We will examine the meaning of the phrases blow your own trumpet and toot your own horn, where these terms came from and some examples of their use in sentences.
The phrases to blow your own trumpet and to toot your own horn mean to brag about one’s achievements, to boast about one’s skills or successes. Blow your own trumpet is most often used in British English and toot your own horn is most often used in American English, though they may overlap. The terms come from the practice of announcing the arrival of an important guest at a formal gathering with a fanfare of horns.

These phrases are often used today in a self-deprecating way when one wishes to modestly point out a personal success.
