Appoggiaturas must always receive a positive accent , never a negative one ; accentuate the first note and play the resolution with less volume .
倚音一定总是有明确的加重音符号，决不会不加重；用较小的音量来演奏和强调第一音符。
Dissonant grace notes , the most common of which are appoggiaturas , are played on the beat ; they should be emphasized , they add spice to music , but the degree to which they are emphasized is subject to the discretion of the performer .
