Concept

The concept behind the abacus guitar would be to demonstrate to a child the links between  math and music. By observing numbers change on a screen on the child-size guitar, the child must move abacus rings up and down the strings of the guitars to certain frets. Each string could be a multiple of 10 (1, 10, 100, 1000), and the frets could be numbers 0-9. The child would have to make the number by adding up the strings. Strumming would commit their answers to the guitar. The numbers could add up to make chords, and by playing numbers, the child could learn simple songs.

This idea was a combination between  my general interest in math, as well as I started learning guitar recently.
