In short, It’s an open tuning, isn’t it?

Some people misunderstand that the state at the time of mounting Qactus is open tuning (an anomaly setting tuned so as to harmonize with a specific chord only by opening string), but it is different. Because open tuning collapses the position of regular tuning, even professional musicians often get confused. Qactus is “to bring all beginners safely to the next stage” and sticks to reducing the work burden without collapsing the original form position.
