MusicGrid approached the project as a full sonic branding system rather than a one-off composition. The process centered on translating Trolley’s brand values into sound across multiple touchpoints, ensuring consistency and emotional resonance.
At the core of the identity is a simple three-note motif. This motif serves as the foundation for all sonic expressions, allowing the sound to evolve across formats, tempos, and contexts without losing recognition.

Trolley needed a sound that felt joyful, energetic, and modern while remaining distinctive and ownable. The challenge was to strike a balance between simplicity and depth, ensuring the Sonic Identity could work across both digital experiences and larger brand expressions.
The system also needed to feel timeless rather than trend-driven, and adaptable rather than fixed

MusicGrid developed a complete Sonic Identity system built around a modular Sonic DNA. This system allows Trolley’s sound to adapt across different use cases while maintaining a consistent emotional core.
The scope of work included:
Each asset was designed to work independently while reinforcing a unified brand sound.

To mark the launch of Trolley’s first-ever Sonic Identity, MusicGrid created a special orchestral interpretation of the Sonic DNA in collaboration with the Macedonian Philharmonic Orchestra.
This orchestral version translated the core motif into a cinematic expression of movement, energy, and optimism, demonstrating how the Sonic Identity can scale beyond digital touchpoints into larger brand moments.
The result is a cohesive sonic system that supports Trolley across digital experiences and future campaigns, providing consistency, emotional resonance, and long-term flexibility while maintaining a clear and recognizable sound.
