My new sound composition launched online as part of a project by Cities and Memory – exploring the sounds of the world’s most famous sites:

About the work

Machu Picchu Paces is a sound art composition based entirely on a field recording from a five-day trek along the Inca Trail. Inspired by my own journey in 2024, the piece explores walking as rhythm and ritual—using time scaling to adjust step rates and simulate group dynamics, from slow hikers to swift porters. Subtle variations and minimal processing reveal unexpected textures in the layered footfalls, evoking both exertion and abstraction. The piece reflects on tourism, physicality, and collective movement along this historic path. Machu Picchu Paces highlights the sonic heritage of a journey that connects travelers across centuries.

About the project

Sonic Heritage is the first collection of the sounds of the world’s most famous sights.

The project presents the sounds of 270 UNESCO World Heritage sites and items of intangible heritage – all reimagined by artists from around the world to create a brand new way of experiencing these spaces.

Fade (2017), detail from installation at 92Y Art Center

Trio is a multiscreen installation of abstract digital images, each a visual echo of a distinct three-note chord from a string trio score by first-generation minimalist composer Tom Johnson.

Opening reception: Tuesday, May 16th at 6:30pm

Hours: May 14–19th, 12–6pm

May 20-21 Sat/Sun (by appointment)

Subway: F/M/D/B Broadway/Lafayette, R to Prince, #6 to Bleecker

Presented on four large screens, the images were created with custom software based on 288 combinations of violin, viola, and violoncello notes.

Each of the 49 notes used in Trio’s musical scale is assigned a color and a simple rectangular shape with dimensions determined by the note number. These shapes — known mathematically as ‘straight polyominoes’ — were inspired by the combinatorics at the heart of the string trio score. A note, represented by the same shape repeated either vertically or horizontally on the screen, is stacked with the two other visually translated notes to form a composite visual abstraction. Appearing architectonic yet malleable, these emergent visual compositions operate in their own realm as a series of digital paintings, one gently flowing into the next.

Galbraith’s installation continues a body of work exploring alternative relationships between sound and image enabled by software designed to cross media boundaries and form a new audiovisual composition environment.
