How is a banjo different from a guitar?
Although the banjo and the guitar are related, the major differences between them are that the banjo uses a drum to move the air and make sound, whereas the guitar uses a wooden box with a hole in it. By far the most popular kind of banjo is the five-string, and it has a re-entrant tuning. What this means is that the strings go down in pitch and then go back up again. This causes the fingering system on a five-string banjo to be radically different than that of a guitar, mandolin, or any sensible instrument.
