In music, an accent is an emphasis placed on a particular note, either as a result of its context or specifically indicated by an accent mark. Accents contribute to the articulation and prosody of a performance of a musical phrase. Compared to surrounding notes: * A ''dynamic accent'' or ''stress accent'' is an emphasis using louder sound, typically most pronounced on the attack of the sound. * A ''tonic accent'' is an emphasis on notes by virtue of being higher in pitch as opposed to higher in volume.〔http://www.vocabulary.com/dictionary/tonic_accent#word=tonic%20accent〕 * An ''agogic accent'' is an emphasis by virtue of being longer in duration. Accents which do not correspond to the stressed beats of the prevailing meter are said to be syncopated. ==Agogic accents== There are four kinds of agogic accent: * Longer notated duration of a note, for example, a half note among quarter notes. * Extended duration of a note within its full-time value (without altering the tempo). For example, players of organ and harpsichord (which do not afford the use of dynamic accents) can emphasize one of a sequence of staccato quarter notes by making it less staccato. * Extended duration of a note with the effect of temporarily slowing down the tempo. * Delayed onset of a note. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Accent (music)」の詳細全文を読む スポンサード リンク
