Other forms: accent marks
An accent mark is a symbol used in pronunciations and in musical notation to indicate which syllables or notes to stress, or emphasize. An accent mark could also be a special symbol over or under a letter to indicate a special pronunciation: e.g., résumé.
Most dictionary pronunciation guides today place an accent mark before the syllable to be stressed. For example, the International Phonetic Alphabet (IPA) places a high vertical line, like a raised apostrophe, before the syllable with the strongest emphasis, and a low vertical line, like a lowered comma, before a syllable that is stressed, but less strongly: e.g., ˈdændɪˌlaɪən (the IPA pronunciation for dandelion). In music, a different accent mark (>) shows that a note or chord should be emphasized.
