Answer:
Syncopation
, pentatonic scales and modal scales.
Explanation:
<em>Syncopation</em> in music represents an <em>alternation of different rhythms</em> that occurs suddenly so as to break the rhythm's regular flow. It is used in dance music and pieces rich in syncopation induce a <em>desire to move to the music</em>.
<em>Pentatonic scales</em> are music scales containing 5 notes per octave (Ancient Greek <em>pente </em>meaning five) and they root from ancient civilizations. This scale was discovered naturally through human's innate sense of music.
<em>Modal scales </em>can be derived from one <em>major scale </em>with a different starting tone. One of the most common modes is <em>Aeolian</em>, which starts at the sixth major scale tone.
All of the above are the specific elements present in romantic music (XIX century).
