Even AI knows that line can't go down. Line does not go down. Line must not go down. Line only go up.
I'm not joking I generated 20 different images with this exact prompt and not one of them had the line go down. Turns out the tankies were wrong after all, line can only go up
It would probably make more sense with a five string bass. Then you would tune the B down to A, the E down to D, the A down to F, the D down to A, and I guess the G string down to C so you could get a major triad on the high strings. That way you avoid any neck strain with tuning up.
