◆ Like the piano, it is up from the left in ascending order, and One chord is composed of 12 notes. Demonstrate the expressive power that makes the best use of the wide range of 5 octaves. With just one finger, you can play the glissando of only One chord, which is difficult with a normal keyboard. You can also adjust the length of the keyboard from the menu, making it suitable for people with large fingers.
◆ [Chord-Tambourine] → While it is a simple performance that you just hit a big button at a constant tempo, the composition sound of the sound is automatically changed by the number of fingers you touch, and you can also play "chord glissando ↗" by swiping.

◆ Personal development story ◆
One of my family who loved music got dementia.
I saw her hobby instruments and singing lost at the facility where she moved in.
I thought that if there was an instrument that anyone could easily play anytime, anywhere, it would be a movement of the fingers and training her brain, and dementia could be alleviated.
I wasn't in time for the family, but music has the power to heal people mind, so I hope many people will find it useful for same or other purposes.
