What if… this 10 foot guitar sculpture existed, and you could walk up to it, slide the points hold up the strings to change the pitch?
With six strings you could make chords.
You then bang or twang on the strings to make sounds.
You can also slide the points up and down to vary the pitch while you twang.
The red knobs would make sliding the bridges comfortable.
Many questions linger:
What material to make the top and back?
What material to build the sides?
What will it sound like?
