If you think YOU'VE got problems of the changing of one string throwing other strings out of tune, try the banjo! Because the banjo head is thin and flexible, and its tension is what keeps the un-fastened bridge in place beneath the strings, every change in tension of the strings firms up or slacks off the firmness of the head, and affects the tension of the strings.What's more, with a five-string, when you capo you will usually need to retune the fifth string, leading to the problem in the first paragraph.
The bottom line is the well-known observation that YOU CAN'T TUNE A BANJO!
