What is the difference between guitar and ukulele?
Guitar and ukulele are similar instruments. But there are many differences between them:
- The biggest difference is that a ukulele is much smaller than a guitar.
- Second, the ukulele has four strings while the guitar has six strings. Ukulele is tuned to G-C-E-A, while the guitar is tuned differently as E-A-D-G-B-E.
- Next, the sound is different. The guitar sounds much fuller than the smaller-body ukulele.
- Ukulele usually comes with nylon string, while the acoustic guitar usually comes with steel ones.
- Scale length. The length from nut to the saddle is much longer in a guitar. 
- Difficult to play. The six strings make the guitar a little more difficult to play than a ukulele.
