Who Composed the Windows XP Startup Sound?

The iconic Windows XP startup sound, known officially as "Windows XP Startup," is one of the most widely recognized audio signatures in modern digital history. This article explores the creative origin of the beloved chime, detailing the work of composer Bill Brown and sound designer Tom Ozanich, who collaborated with Microsoft to create the audio identity for the operating system launched in 2001.

Bill Brown, an accomplished American composer best known for his work in video games, television, and film, was commissioned by Microsoft in the early 2000s to compose the audio identity for Windows XP. Prior to this project, Brown had established a reputation in the interactive entertainment industry, scoring titles for major franchises such as Tom Clancy's Rainbow Six, Ghost Recon, and Lineage II.

For Windows XP, Microsoft sought a sound that felt warm, welcoming, and optimistic, moving away from the more mechanical or synthesized tones of earlier computing eras. Working alongside sound designer and mixer Tom Ozanich, Brown crafted a lush, orchestral harmonic progression that resolved cleanly to signify that the computer was ready for use.

The composition relied on rich orchestral layering and spatial acoustic design rather than purely electronic synthesis. Brown utilized live orchestral instrumentation blended with subtle ambient pads to achieve the uplifting, acoustic quality that defines the final track. Tom Ozanich then mixed the piece to ensure it would translate clearly across a wide spectrum of consumer audio hardware, from high-end desktop speakers to low-fidelity built-in monitor speakers.

The creation of the XP startup chime placed Brown in an exclusive group of composers chosen to define Microsoft’s operating systems. This tradition began when ambient music pioneer Brian Eno created the startup chime for Windows 95, and continued later when King Crimson guitarist Robert Fripp contributed sounds for Windows Vista.

Because Windows XP remained one of the most widely used operating systems for well over a decade, Bill Brown's brief composition was heard billions of times worldwide, cementing its status as an enduring artifact of early 2000s technology and pop culture.
