Upbeats are lighter than downbeats .

弱拍比强拍要轻。

When measures are syncopated , the upbeats are emphasized .

当有切分音的小节里，重音在弱拍上。

If we play upbeats with the same intensity as downbeats , we appear to be accenting the weak part of the bar ; melodies played this way sound syncopated .

如果我们演奏弱拍时与第一拍的强度一样，看来我们是要加重这一小节中的弱拍；用这种方法演奏发出的声音是切分音。
