Geometry Dash is a game deeply intertwined with music. Many players focus solely on the visuals, overlooking the significant advantage gained by sensing the rhythm.
The music often provides crucial cues regarding the appearance of obstacles or shifts in gameplay mechanics. Familiarity with the track allows players to anticipate what comes next, even before the full level is visible.
This is why many gamers can drastically improve their performance simply by repeatedly listening to the music of the level they are practicing.
