Play 3D

The 3D mode shows the same chart, notes, and scoring as Play 2D, but renders a 3D harmonica model in front of the camera with notes flying toward it — a more immersive, “you are holding this harmonica” view of the same gameplay.

• The harmonica model matches your selected note theme/harmonica model (Options), and reacts live to what you actually play.
• Optional hole-number labels (Options → Note labels) show as small dark pills near each incoming note, the 3D equivalent of 2D’s on-note labels.
• Chromatic harmonicas don’t yet have a dedicated 3D model — a diatonic model is shown in its place if you’re playing a chromatic chart in 3D.

Scoring, the HUD, pausing, A–B looping, Wait for Note, Practice Speed, and Adaptive Difficulty all work exactly as described in Playing a Song — 2D and 3D are purely a visual choice made once, at Select Mode.
