Few songs in the history of popular music capture the fragile emotions of heartbreak and loneliness as beautifully as “What’ll I Do.” When Johnny Mathis recorded his version in the early 1960s, he transformed an already beloved classic into a deeply emotional masterpiece that continues to resonate with listeners decades later. His gentle voice, emotional delivery, and elegant orchestration turned the song into one of the most memorable interpretations of the American songbook era.
Originally written by Irving Berlin in 1923 for the Music Box Revue, “What’ll I Do” quickly became a standard song performed by many artists. However, Johnny Mathis’s version brought a new level of vulnerability and romantic melancholy that helped introduce the song to a new generation of listeners. His recording appeared on the album Wonderful Wonderful, which became one of the defining albums of his career.
A Song About Loss, Loneliness, and Emotional Uncertainty
At its core, “What’ll I Do” is a song about emotional loss — the kind of loss that leaves a person feeling directionless and empty. The lyrics are simple, yet incredibly powerful. Instead of dramatic storytelling, the song focuses on a single question repeated throughout the melody: What will I do when you are gone?
This question represents something universal. Everyone, at some point in life, experiences separation — whether through a breakup, distance, or even death. The song captures that moment when someone realizes their life has changed forever, and they don’t know how to move forward.
Johnny Mathis’s interpretation emphasizes this emotional uncertainty. His voice is soft, controlled, and filled with quiet sadness rather than dramatic sorrow. This subtle emotional delivery makes the song feel more personal, almost as if he is singing alone in a quiet room, reflecting on memories of someone he loved.
Johnny Mathis’s Vocal Style and Emotional Delivery
One of the reasons Johnny Mathis’s version stands out is his unique vocal style. He never needed to shout or over-sing to express emotion. Instead, he used smooth phrasing, gentle vibrato, and careful control of dynamics to communicate vulnerability.
Listening to his version of “What’ll I Do” feels like listening to someone thinking out loud. His voice carries a sense of nostalgia, regret, and longing all at once. The orchestral arrangement — usually featuring soft piano, strings, and light background instrumentation — supports his voice without overpowering it. The music almost feels like it is “breathing” with the singer.
This style was typical of Johnny Mathis during the late 1950s and early 1960s, when he became famous for romantic ballads and emotional love songs. His music often focused on themes like love, heartbreak, memories, and longing — themes that remain timeless and relatable even today.
The Legacy of Irving Berlin’s Songwriting
To fully appreciate the song, it is important to recognize the genius of Irving Berlin, one of the greatest songwriters in American music history. Berlin wrote hundreds of songs, many of which became standards, including classics like “White Christmas,” “Cheek to Cheek,” and “Blue Skies.”
“What’ll I Do” is different from many of his more upbeat songs. It is slower, more reflective, and emotionally intimate. The melody is simple and elegant, allowing the lyrics and emotion to take center stage. This simplicity is actually what makes the song so powerful — it feels honest and sincere rather than overly dramatic.
When Johnny Mathis recorded the song decades later, he respected the original composition but added his own emotional interpretation. His version feels more romantic and melancholic, while still preserving the timeless beauty of Berlin’s songwriting.
Why the Song Still Resonates Today
Even though the song was written over 100 years ago and recorded by Johnny Mathis more than 60 years ago, “What’ll I Do” still resonates with listeners today. The reason is simple: the emotions in the song are universal and timeless.
People still fall in love.
People still lose love.
People still feel lonely.
People still ask themselves what to do after heartbreak.
Music that deals with real human emotions never becomes outdated. Technology changes, music styles change, but feelings of love and loss remain the same across generations.
When modern listeners discover Johnny Mathis’s version, they often feel surprised that a song recorded so long ago can still feel so emotional and relevant. That is the mark of truly timeless music.
A Quiet Masterpiece of Emotional Music
“What’ll I Do” is not a loud song. It is not dramatic or theatrical. Instead, it is quiet, gentle, and deeply emotional. It is the kind of song that feels best listened to alone at night, when the world is quiet and memories become louder.
Johnny Mathis had a special talent for songs like this — songs that did not rely on complex arrangements or powerful vocals, but instead relied on emotion, sincerity, and atmosphere. His version of “What’ll I Do” remains one of the most beautiful interpretations of the song ever recorded.
The song reminds listeners of something very human: love leaves a mark, and when love disappears, it leaves silence, questions, and memories behind. That simple emotional truth is what makes the song so powerful.
Final Thoughts
Johnny Mathis’s “What’ll I Do” is more than just a classic song — it is an emotional experience. It captures the feeling of loneliness after love is gone, the confusion of moving forward alone, and the quiet sadness that comes with remembering someone who is no longer there.
Through his soft voice and heartfelt interpretation, Johnny Mathis turned Irving Berlin’s classic into a timeless ballad that continues to touch listeners across generations. The song remains a beautiful reminder of how powerful simple music can be when it speaks honestly about human emotions.
Even today, when people listen to “What’ll I Do,” they often feel the same emotion listeners felt decades ago — a quiet sadness, a sense of nostalgia, and the universal question that echoes after love fades away:
What will I do without you?
