The structure of music is called “musical grammar” or “musical theory.”
Learning by listening is easier than learning by reading, but it is still possible.
This page is designed for people who have no knowledge of what musical theory is about. You can learn at your own pace.
If you have figured out the “QactusCore-Method”, you will be able to learn and enjoy music differently.
However, sometimes it may be difficult.
Try to enjoy and study without becoming frustrated.
