[Tooltips]

If you are on a PC, hover over each chord progression to see additional notes in a tooltip.
Some of the comments are fairly tongue-in-cheek, but feel free to use them as reference.

[Quick-Switch Menu]

After scrolling down a bit, a quick-switch menu appears at the bottom right of the screen.

The left and right arrow buttons switch the key in semitone steps.
* When switching keys with these buttons, enharmonic keys are skipped.
Pressing the key-signature button in the middle toggles between chord-name display and degree-name display.

If you are on a PC, simple playback controls (BPM, pattern, pattern tempo, loop) are also shown above it.

The menu follows the scroll, so you should not have to go back to the top of the page every time you switch keys.

[Before You Use These]

The chord progressions listed here are presented in as plain a form as possible.

You do not have to use them exactly as they are. Feel free to experiment.

- Example 1: F-G-Em-Am-F-G-C-E (combining the "Royal Road" and "Emo" progressions)
- Example 2: Dm9-Eaug-Em7/A-C9 (the "Marusa progression" with tensions added and some chords replaced by substitutes)

(Of course, you may also use them exactly as they are.)

[Names / Notes]

The "names" and "notes" are written according to the developer's own judgment and biases.
Everyone feels music differently, so you can use these progressions even outside the situations described.

[How Chords Are Categorized]

On this page, degree names are interpreted from a fixed major-key perspective.
(For example, the "Am" chord is written as "Ⅵm" in both the C major key and the A minor key.)

Some consider this approach "not appropriate".
However, we adopt it because it conveniently lets you think about multiple modes sharing the same key signature using common degree names.

---

[Tendencies of Chord Progressions]

Following the approach above, most chord progressions start on the key's Ⅰ, Ⅳ, or Ⅵm.*
* This is a rule of thumb; there is no statistical data behind it.

It is generally said that progressions starting on Ⅰ give a bright impression, while progressions starting on Ⅵm give a dark impression.
