李瑪寶老師澆灌過的『長中合唱團』幼苗轉變成熟枝葉『長中校友合唱團』到轉型開放徵選的MP Singers『混聲合唱團』。不論那時期的校友，多年後重聚一起，不僅跳脫青春期的羞澀懵懂讓和聲更趨沈穩踏實，更讓每個樂音表現出豐盛的歡愉與甜美。因為音樂，讓團員們超越時空而緊緊相繫，正如同跨越不同小節線的音符，共同譜成一曲悅耳動聽的樂章；因為信仰，讓彼此在這條路上無私的奉獻，像被熱情點燃的生命蠟燭，為廣大的社會人群發光發亮。人生雖像合唱曲一般充滿了酸甜苦辣，但MP所唱出的優美歌聲，能在這個紛擾不斷的社會營造不滅的光亮！

“MP Singers Chamber Choir”, led by Miss Mapao Lee, is the transformation from another two of her choirs “CJ Choir” and “CJ Alumni Choir”. The members of the later only come from Chang Jung Senior High School, but MP Singers Chamber Choir is opened for everyone who is passionate with choral music. The alumni get back together after graduated from school for years. Their sweet and joyful voices have now become more mature than before. For the music, the choir members return to this family and stay close as if a lovely piece of music, which is formed by the notes on the sheet music; for the faith, the members devote themselves unconditionally as if a lighted candle, shining up for this world. Life is full of happiness and bitterness, just like choral music. However, the beautiful music MP Singers Chamber Choir brings to the world will always be the light that will never end.
