I would like to understand the music theory idea behind ChordJam:
I can choose a scale (C-B), a scale type (Minor, Major, …) and additionally a ChordType (Major Scale, Minor Scale, Minor9, …)
I have two questions:
- I don`t get how scale type and chord type get together. What is e.g. happening, when I choose scale type “Major” and Chord Type “Minor 9”? What is the logic behind this?
- When I choosed a scale type, I can play the fitting chords on the keys of my keyboard. Example: I choosed C Major and now I can play Cmaj, Dmin … but when I play C# on keyboard, it plays a Csus4. Why?
Is this question stupid? I do not find the answer, not in the docs neither in the overview video
Ok, and I forgot to add the category: @admins Could you add “Help & Support”?
The Chord Type adjusts the chord that is playing and does not make any changes in the selected scale. I will try to explain it with the example below:
Let’s say that your scale is C Major and your scale type is Major too. By pressing the C key, it plays the C-E-G chord as expected.
Now, let’s set the scale type to minor scale. By pressing C, it plays C-D-G.
Chordjam “tries” to play a minor chord, which typically would be C-E♭-G. However, E♭ does not belong to your selected scale which is C Major. For this reason, Chordjam brings E♭ to the closest lower note that exists in the selected scale (E♭ → D) and it plays C-D-G instead.
To make it play C-E♭-G, you have two options:
- Set the scale type to Chromatic: In this case, Chordjam would play its chords according to the chord types that you have selected.
- Or set the scale type to minor and the chord type to minor too.
