Branded music or sonic identity refers to a broader strategy that includes the brand’s overall sound palette—such as background scores, theme music, and audio environments, crafted to reflect the brand’s personality and values across different touchpoints.
In this music exploration, we focus on the melody—the main tune you hear—which is crafted to follow the intonation and syllabic emphasis of “Hamkaran System.” The rises and falls in the melody align with how the name is spoken, creating a catchy and recognizable motif. This makes the sound logo instantly relatable and helps embed the SG brand name in the listener’s memory. “Hamkaran System” is the Persian brand name of System Group (SG).
This main melody is also developed further through musical variations and colorful orchestration, tailored to align with each of SG’s sub-brands and their specific functionalities and market targets.

Sepidar covers accounting, finance, payments, inventory, and sales, and includes solutions for manufacturing, contracting, and service businesses. It features a more serene, serenade-like coloring, composed for a large group of string instruments.
Rahkaran is reflected through a full orchestra, including strings and wind instruments, especially brass, highlighting its comprehensive and large-scale nature.
Rahkaran Omoomi and Rahkaran Abri are composed to represent their very different audiences:
Rahkaran Omoomi, SG’s integrated ERP for the public sector—managing finance, administration, HR, and operations in government and public institutions—has a large-scale orchestration that speaks to governmental bodies and large enterprises.
Rahkaran Abri, SG’s cloud-based ERP solution aligned with modern technologies, aims to musically illustrate the concept of the cloud—as a secure, data-storage platform—with light, airy instrumentation.
Dasht, software designed for retail businesses, is represented with wind instruments, reinforcing its image as a highly reliable brand.
