Same things that they both have:
1. Guitar and ukulele both have a neck.
2. They both have tuning pegs.
3. They both have a sound hole.
What are some things that are not the same on ukulele and guitar:
1. Guitar sounds louder.
2. Ukulele has 4 strings but on a guitar it has 6.
3. Ukulele is smaller than a guitar.
I fine ukuleles more easy to play because they are smaller and are much more easy to play.
