If you have the basic knowledge of electronic organ, I suggest you learn double-row keys. First of all, the double-row keys are similar to the electronic organ, which does not require high finger independence and hand shape. Unlike the piano, if you have been learning the electronic piano, it will definitely take several months to turn the piano, and it will take at least 1W for the corrector. Secondly, if you practice every day, you must adjust it once every six months. But a Yamaha also costs about1w. Finally, most people learn piano in China, and the competition is too great, but many people don't know about the double-row keys. Also depends on the purpose of learning musical instruments. If you want to take the exam, choose the double-row key. If it's just for fun or as an interest, then both can be PS: I'm learning piano, and now I'm also learning double-row keys. At first, I felt that the foot keyboard was a bit difficult, and my feet were always uncoordinated. I have always been afraid of stepping on the wrong foot, but I am familiar with the foot keyboard and can use it with my hands, so I step on it by feeling. In fact, double-row keys are still easy to learn, and the key is to practice more.
