Chords Pad

This app can easily check the sound and the display on the keyboard of the chord tone of musical chords.
We have prepared various UI for checking the chords. Use the method that suits you from the items below.

- Pad Display - Chord List
- Pad Display - Custom Pad
- Chord Progress

[Chord List]
Displays all types of chord patterns in a list for each key. It supports chord reordering and toggling chord visibility.
The root position and inversions of the selected chord are displayed as chord buttons below the chord list. (Example: CM7, CM7/E, CM7/G, CM7/B)

[Custom pad]
Larger buttons than the chord list are arranged. You can freely set the chord and key for each button.

[Chord Progress]
Add common chord progressions from presets or create your own. You can also edit individual chords, transpose, reorder, and delete chord progressions.

In either case, when the chord button is tapped, the selected chord is played and the chord tone is displayed on the keyboard.
* If you'd like to display all the chord patterns including tension (b9, # 9, 11, # 11, b13, 13), You need In-App Purchase.

[Chord inversion area]
When you select a chord in "Chord List" or "Custom Pad," its root position and inversions appear below the chord button area.
Example:
- CM7 : C E G B (Root position)
- CM7/E : E G B C
- CM7/G : G B C E
- CM7/B : B C E G
The note after "/" indicates the bass note. Scroll horizontally through the inversions and tap a button to play it and display its notes on the keyboard.
The inversion area for "Custom Pad" can be shown or hidden with "Inversion display" in Settings.
