A chord is a group of notes with the same start time. Closely spaced chord events create chordjack-like structure. Some pairs in this diagram repeat, and later pairs move to other columns.

Open the diagram to view the full-size image. These are original timelines, not screenshots of a real map. Column numbers are not keyboard bindings. The example is illustrative rather than a test of the entire-chart classifier.

The analyzer looks for consecutive multi-key events close together, the share of chord events, and chordjack runs. It does not require every chord to use identical columns.

Use either form as an active player. The shared room’s future selections use the preference; already visible queue entries stay in place. Use .style or .map to inspect the current Mania chart and .pool for active filters.

A single isolated chord is not a repeated chord sequence. A chart can also contain single-note streams, jacks, or long notes; style scores are not exclusive categories.

When strict fresh choices run out, style fallback can broaden the selection while keeping the active eligibility boundaries. Expanded spelling aliases are supported in the confirmed live v6.6.17 release.

See the visual pattern atlas, the command reference, practical style examples, and style selection.
