* Guitars typically have six strings, while banjos typically have five strings. The guitar's strings are typically tuned E, A, D, G, B, and E, while the banjo's strings are typically tuned G, D, G, B, and D.
* Guitars are fretted instruments, meaning that the notes are determined by where you press your fingers on the strings. Banjos are not fretted instruments, so the notes are determined by where you place your fingers on the strings without actually pressing down.
* Guitars are typically plucked with a pick, while banjos are typically plucked with the fingers.
* Guitars typically have a wider range of tones and sounds, while banjos have a more limited range. However, banjos do produce a unique, twangy sound that complements acoustic guitars quite well.
Ultimately, the choice of which instrument to learn first is a personal one. Some people may find it easier to learn guitar first, while others may find it easier to learn banjo first. The best way to decide which instrument is right for you is to try both of them out and see which one you enjoy playing more.
