Music has been a cornerstone of World of Warcraft since the MMORPG launched 22 years ago, but in 2026, the approach to Azeroth’s soundscape is shifting. As the game moves through the Worldsoul Saga—the first connected trilogy of expansions—the audio team is tasked with balancing a three-decade legacy with the needs of a modern, story-driven experience.
I recently spoke with lead composer Leo Kaliski, Music Director Derek Duke, and Principal Producer Charlotte Pyle about the pressures of maintaining that history. "WoW has such a long history of music and so many themes—that was probably one of the most daunting things when I came on as the lead," Kaliski says. The team must navigate the expectations of a fanbase that is quick to notice if new music doesn't feel faithful to established cultural themes, such as specific variations of Troll or Night Elf musical identities.
A Collaborative Melting Pot
The scale of the game is reflected in the team's composition process. For the Midnight expansion, nine composers are contributing to the score. According to Kaliski, this "melting pot" of voices helps the world feel as large as it is. "It’s not one person’s voice, it’s a lot of different voices," he notes.
This variety is a departure from the game’s early days, which relied heavily on ambient tracks to support a community-focused experience. As the story has become more cinematic, the music has followed suit, demanding bolder and more defined themes. However, the team remains committed to the game's ambient roots. Kaliski emphasizes that they avoid playing heavy, cinematic music for players simply engaged in casual activities like leveling Herbalism.
The Worldsoul Throughline
The connected nature of The War Within, Midnight, and The Last Titan has fundamentally changed how the team approaches composition. Rather than being confined to a single theme per expansion, they now have the ability to weave an audio narrative across years.
For the Worldsoul theme, the team built a base foundation and then developed multiple variations—sad, action-oriented, uplifting, and evil versions—to suit different gameplay contexts. This allows the music to evolve alongside the story, with the team finding more space for these themes to live within the game as the saga progresses into Midnight and beyond.
Managing Player Fatigue
One of the biggest challenges for an MMO is ensuring that music doesn't become repetitive during long play sessions. Pyle explains that the team creates a "hero" version of a track, then separates the recordings by instrument—strings, wind, brass, and percussion—to create distinct variations. For Midnight, this process turned three hours of hero music into 15 hours of implemented audio.
"Fatigue is a big thing we look for in music," Kaliski explains. "As soon as someone is getting bored of the music and it's starting to wear on them, that's when they're going to turn it off." In Midnight's Voidstorm zone, the team actively adjusted the music to include more ambient, less driving versions to provide a kinder, long-term experience for players.
These efforts extend to experimentation, such as the widely praised Goblin Jazz album, and more complex boss encounters. Kaliski points to the boss track for Dimensius in the Manaforge Omega raid as a highlight of this new, narrative-focused approach. Because the community responded positively to that level of detail, the team plans to continue investing in high-quality, cinematic boss music in future updates.
"We are always looking to level up," Duke says. "We never rest on our laurels, we are always trying to keep moving forward."
