Some songs never lose their emotional power, no matter how many decades pass. They continue to speak to listeners because they capture feelings that every generation experiences—love, longing, loneliness, and the painful uncertainty that follows goodbye. Irving Berlin’s “What’ll I Do” is one of those rare compositions. Since its debut in the early twentieth century, it has remained one of the most touching standards in the American songbook. Yet among the many artists who have interpreted this unforgettable ballad, Johnny Mathis delivered one of its most heartfelt and enduring performances.
Released in 1962 as both a single and a featured track on his acclaimed album Wonderful Wonderful, Mathis’ rendition introduced the beloved classic to a new audience while preserving every ounce of its emotional depth. His version climbed to No. 23 on the Billboard Hot 100, adding another memorable success to an already remarkable career. The album itself also enjoyed considerable popularity, reaching No. 11 on the Billboard Top LPs chart, further solidifying Mathis’ reputation as one of America’s premier interpreters of romantic ballads.
More than sixty years later, What’ll I Do continues to stand as one of the finest examples of Johnny Mathis’ extraordinary ability to transform a familiar standard into something deeply personal. It is a performance built not on dramatic flourishes or overwhelming vocal power, but on sincerity, elegance, and emotional honesty.
A Song That Asks One of Love’s Most Difficult Questions
Originally written by legendary composer Irving Berlin for the 1923 Music Box Revue, What’ll I Do quickly established itself as a timeless reflection on separation and loss.
Its premise is remarkably simple.
After someone deeply cherished leaves, the singer is left facing an uncertain future, asking a question that has echoed through generations:
“What will I do?”
It is not merely a question about loneliness. It is a reflection of emotional disorientation—the feeling that life itself has lost its rhythm after someone who once gave it meaning is no longer there.
Rather than offering hope or easy answers, the lyrics embrace vulnerability. They acknowledge that grief often begins with confusion, with quiet moments when the absence of a loved one feels impossible to comprehend.
This emotional honesty explains why the song has endured for more than a century. Every listener who has experienced heartbreak can recognize the uncertainty hidden behind those four simple words.
Johnny Mathis Brings Extraordinary Tenderness to the Classic
Johnny Mathis possessed one of the most recognizable voices in popular music. His warm tenor, remarkable breath control, and effortless phrasing allowed him to communicate emotions with remarkable subtlety.
In What’ll I Do, those qualities become the heart of the performance.
Rather than treating the song as a theatrical lament, Mathis approaches it with quiet restraint. His delivery feels intimate, almost conversational, as though he is sharing private thoughts instead of performing for an audience.
Every lyric carries genuine emotion without ever becoming sentimental or exaggerated.
His voice glides gracefully through Berlin’s elegant melody, allowing each phrase to linger naturally. There are no unnecessary vocal displays or dramatic climaxes. Instead, Mathis trusts the beauty of the composition and lets sincerity become the song’s greatest strength.
That understated approach makes the performance all the more powerful.
The Elegant Simplicity of the Arrangement
One of the defining characteristics of Johnny Mathis’ recording is its beautifully understated orchestration.
Soft piano lines provide the emotional foundation, while delicate strings gently surround the vocal without overwhelming it. Every instrumental detail serves the story rather than distracting from it.
The arrangement creates an atmosphere that perfectly mirrors the song’s emotional landscape.
Listeners can almost picture a quiet evening after everyone else has gone home. The room is still. Memories begin to surface. Silence becomes impossible to ignore.
Against that backdrop, Mathis’ voice becomes the emotional center of the recording.
The production never rushes the listener. Instead, it allows every pause, every sustained note, and every gentle orchestral swell to deepen the feeling of longing.
It is a reminder that sometimes the most powerful musical moments come from restraint rather than excess.
Bringing a Classic to a New Generation
By the time Johnny Mathis recorded What’ll I Do, the song had already enjoyed decades of popularity.
Irving Berlin’s songwriting had become an essential part of American musical history, and countless artists had introduced his compositions to audiences around the world. Yet Mathis managed to make the familiar melody feel completely fresh.
His interpretation respected Berlin’s original vision while adding the warmth and emotional sophistication that had become his trademark.
For listeners discovering the song in the early 1960s, Mathis offered an interpretation that felt contemporary without sacrificing its timeless elegance.
That balance between honoring tradition and creating something uniquely personal became one of the defining characteristics of his career.
Whether singing Broadway standards, popular ballads, or romantic originals, Johnny Mathis consistently demonstrated an extraordinary gift for making every song sound as though it had been written specifically for his voice.
Why the Song Continues to Resonate
Although musical styles have evolved dramatically since 1962, the emotional message of What’ll I Do remains remarkably relevant.
Loss has never belonged to one era.
Every generation experiences separation, broken relationships, distance, and grief. While circumstances may change, the emotional questions remain the same.
How do you move forward after someone important is gone?
How do ordinary places suddenly feel unfamiliar?
How do you rebuild a future when someone who once defined it is no longer there?
These are universal experiences, and Johnny Mathis communicates them with remarkable compassion.
His performance never attempts to provide solutions or optimistic conclusions. Instead, it simply acknowledges the reality of heartbreak with grace and dignity.
Sometimes that quiet understanding is exactly what listeners need.
The Lasting Legacy of Johnny Mathis’ Interpretation
