Cheng Chih-jen's phrasing and lyrics are simpler. For example, in "Eagle" he makes much use of syncopation. This makes the tune very lively and easy to learn, yet it is still very challenging to the vocalist if one tries to sing it to a serious professional standard.
鄭智仁的歌樂句與歌詞比較簡單，但如「獵鳶」一曲中使用了許多後半拍，聽起來曲子很活潑，學者能朗朗上口，但若聲樂家想認真唱來卻也難度很高。
