APP BUILDER: TEACHING APP WITH PLAYABLE QB (9X9) KEYBOARD.
PR PERSON: I AM THE ONLY PLAYER OF THE ONLY QB IN THE WORLD.
There are lots of people who play the piano–there are lots more who would like to be able to play the piano. The QB offers a 2-D keyboard that is capable of performing piano music (look at the QQ website) with several learning advantages.
There are billions of people in the world. I need at least one more QB player. No joke–the QB offers many marketing and performing possibilities.
