There are songs that entertain, songs that inspire—and then there are songs that quietly unravel the human heart. “What’ll I Do,” immortalized by Johnny Mathis, belongs firmly in the latter category. It is not simply a melody or a lyric—it is a question, a fragile emotional thread that stretches across generations, binding listeners through a shared understanding of love and loss.
Originally written by the legendary composer Irving Berlin for his 1923 Music Box Revue, “What’ll I Do” was already a poignant standard long before Mathis lent it his voice. But it was Mathis’s 1962 rendition, featured on his album Wonderful Wonderful, that gave the song a renewed emotional gravity. His interpretation didn’t just revisit the classic—it redefined it for a modern audience, transforming a nostalgic tune into a deeply personal lament.
A Voice That Carries the Weight of Absence
Listening to Johnny Mathis sing “What’ll I Do” feels like stepping into a quiet room filled with memories. His voice—smooth, controlled, and hauntingly tender—doesn’t overpower the listener. Instead, it draws you in, gently but persistently, until you find yourself confronting the same aching question posed in the song’s title.
Mathis had a rare gift: the ability to sound both technically flawless and emotionally vulnerable at the same time. In “What’ll I Do,” that gift is on full display. Every note feels intentional, every pause heavy with meaning. He doesn’t just sing about loss—he embodies it.
The arrangement is deceptively simple. Soft piano chords and subtle string accompaniments create a sonic landscape that feels almost suspended in time. There is no urgency here, no dramatic crescendo. Instead, the music lingers, mirroring the way grief often does—quiet, persistent, and inescapable.
The Universal Language of Heartbreak
At its core, “What’ll I Do” is about absence—the kind that reshapes your world. The lyrics don’t rely on elaborate metaphors or poetic complexity. They are straightforward, almost conversational. And yet, that simplicity is precisely what makes them so powerful.
The question “What’ll I do?” is one that transcends context. It could be asked after the end of a romance, the loss of a loved one, or even the fading of a once-meaningful connection. It captures that moment when the future feels uncertain, when identity itself seems tied to someone who is no longer there.
Mathis’s interpretation amplifies this universality. His delivery doesn’t specify the nature of the loss—it leaves space for the listener to fill in the blanks. That openness is what allows the song to resonate so deeply across different experiences and generations.
Reviving a Classic for a New Era
By the time Johnny Mathis recorded “What’ll I Do,” Irving Berlin had already secured his place as one of the most influential songwriters in American history. His compositions had become part of the cultural fabric, performed and reinterpreted by countless artists.
Yet Mathis managed to do something remarkable: he made the song feel new again.
Released during a period when popular music was beginning to shift toward more contemporary sounds, Mathis’s version stood out for its elegance and emotional sincerity. It reached number 23 on the Billboard Hot 100—a notable achievement for a song rooted in a much earlier era. The album Wonderful Wonderful also enjoyed commercial success, climbing to number 11 on the Billboard Top LP’s chart.
But beyond chart positions, the true impact of Mathis’s rendition lies in its emotional staying power. It introduced a new generation to Berlin’s songwriting while simultaneously reinforcing Mathis’s reputation as one of the most expressive vocalists of his time.
The Art of Emotional Restraint
One of the most striking aspects of “What’ll I Do” is its restraint. In an age where emotional expression in music can often be loud and overt, this song takes the opposite approach. It whispers instead of shouting.
Johnny Mathis understood that sometimes, less is more. He resists the temptation to over-sing or dramatize the lyrics. Instead, he allows the natural melancholy of the melody to guide his performance. The result is something profoundly intimate—almost as if the listener is overhearing a private moment of reflection.
This restraint is what makes the song endure. It doesn’t tie itself to a specific time or trend. It exists outside of them, grounded in emotions that remain constant regardless of era.
Why It Still Resonates Today
Decades after its release, “What’ll I Do” continues to find new audiences. In a world that often feels fast-paced and overwhelming, the song offers a rare moment of stillness—a chance to sit with one’s emotions rather than escape them.
Its relevance hasn’t diminished because the experiences it speaks to—love, loss, uncertainty—are timeless. If anything, its quiet introspection feels even more valuable in today’s noisy digital landscape.
For listeners who have experienced heartbreak, the song serves as a mirror. For those who haven’t, it offers a glimpse into a deeply human vulnerability. Either way, it leaves an impression.
A Legacy Carried in a Single Question
“What’ll I Do” is more than just a song in Johnny Mathis’s extensive catalog—it is a defining moment. It showcases not only his vocal ability but also his emotional intelligence as an artist. He understood the power of subtlety, the importance of connection, and the enduring appeal of sincerity.
In revisiting a classic by Irving Berlin, Mathis didn’t simply pay tribute—he expanded its legacy. He transformed it into something that could speak to the 1960s and beyond, ensuring that its central question would continue to echo in the hearts of listeners for generations.
And perhaps that is the true beauty of “What’ll I Do.” It doesn’t offer answers. It doesn’t resolve the pain it expresses. Instead, it sits with the question, allowing it to linger.
Because sometimes, the question itself is the most honest expression of all.
