《月光小夜曲》的歌詞如下：
今夜啊我仰望月亮灑下的光
照射在寂寞的小村莊
靜謐的夜 夢一樣
喚醒了我的思念和遐想
彎彎的小路依稀在望
又象那條長長彩帶飄向遠方
記得當年我們走過這裡
漫步徜徉多歡欣
在那淡淡月光下相依相伴
愛在心靈深處閃耀著光芒
月色多柔和 伴著輕柔夜曲
重溫往日愛戀情意濃
我的心愿誰能理解
只有月亮明了我的心意
今夜啊我想往昔重現
多么甜蜜多么溫馨
月亮灑下它的光啊
照在我的心上
彎彎小路月光照彩帶飄向遠方
我的愛戀伴著夜曲迴蕩。
以上歌詞為中文版本，蔡琴的《月光小夜曲》還有英文版歌詞，英文版歌詞如下：
I gaze up at the moonlight showering down,
Illuminating the lonely village town.
The still night, a dream,
Awakens my memories and imaginings.
The curved path is clearly visible,
Like a long ribbon floating towards the distance.
Remember when we walked here together,
Strolling and wandering with so much joy and delight?
In that dim moonlight, I held your hand,
And love shone in my heart, radiant and resplendent.
The moonlight is so柔和, accompanied by soft night music,
Returning to rediscover the old sweet memories.
Who can understand my heart?
Only the moon knows my true feelings.
The curved path is illuminated by the moonlight,
My love drifts with the song through the night.
