Quick answer
Music is one of the five confirmed lesson types. In a pre-release hands-on, it used a Guitar Hero-like rhythm activity, and a similar activity returned in a later preview mission. That makes Music the clearest class link for players investigating the Guitar mission.
What is confirmed and observed
Confirmed: Music is an official lesson. Observed: preview gameplay used rhythm input and the previewer felt its timing could be offbeat. Still verifying: final-build inputs, timing window, score thresholds, rewards, controller behavior, and whether any current update changes the experience.
Practical expectation
Use on-screen prompts as the evidence-safe starting point, rather than assuming a universal audio timing rule. The preview is useful context, not proof of a current bug or a mission-specific sequence.
FAQ
Is Music the same as the Guitar mission?
The preview observed a similar rhythm activity in both contexts. The final-build mission relationship, exact name, and requirements are still being checked.
