The appoggiatura is an embellishment that results in one of the most prominent dissonances in many styles. Unlike the accented and unaccented passing notes, the appoggiatura is not approached by step, but by leap. Although it still resolves by step, the dissonance is more prominent as a result.

The third of the above examples below shows what is known as a double appoggiatura - two notes of the chord are initially dissonant and then both resolve by step. The best example of a double appoggiatura is the cadential six-four.
