Learn to recognize chart structures, then follow a pattern’s link for its command, analyzer evidence, and limitations.

Open any diagram to view the full-size image. Columns run left to right. The earliest event is at the top, and time increases downward. Purple short bars are taps; teal extended bars are holds ending at their bottom edge. This is a timeline layout, not a gameplay screenshot. Read the descriptions alongside the images; the text also explains them without images.

The 4K diagrams keep the comparison compact. The Stream article also shows a 7K example. Column numbers are not prescribed keyboard bindings, and the times shown are illustrative.

A jack repeats note starts in the same column at short intervals. In the diagram, every tap returns to column 2.

See the full pattern guide and .jack.

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.

See the full pattern guide and .chordjack.

A stream-like passage is a dense run of single-note starts. This example moves between columns at regular intervals.

See the full pattern guide and .stream.

A long note begins at its head and lasts until its end. The teal bars show hold durations; short purple bars show separate taps.

See the full pattern guide and .ln.

This illustration combines irregular spacing and changing chord sizes across different columns. It shows some of the kinds of variation measured by the technical proxy.

See the full pattern guide and .technical.

The analyzer summarizes a whole chart, not just the passage drawn here. Jacks may also form dense single-note event runs; a chord-heavy chart can have technical timing variation or long notes. One visible label is not an exclusive description of everything in the map.

The current source snapshot uses the descriptive mania_patterns_v1 analyzer. Its scores are selection evidence, not official skill ratings or PP estimates. Style exhaustion fallback can also produce a map outside the strongest requested matches.

Farm is an experimental efficiency-evidence preference rather than a visible pattern shape. Variety includes all eligible structural styles and unclassified charts, with vetted converts where enabled. Neither needs its own misleading note-pattern diagram.

If you recognize repeated chord events and want more of them, use .style chordjack as an active player. Check .queue before judging the next map: previously selected maps stay in place. A different fresh style may reflect exhausted strict choices rather than a rejected preference.
