Students who want to play ukulele at home may want to buy a ukulele of their own!
There are 2 main types of ukulele: soprano ukulele and concert ukulele.

Soprano is smaller and usually cheaper, unfortunately they are often lower quality.  (Buy soprano ukuleles - Thomann online)

Concert ukuleles are only a little larger but have a nicer sound and are usually better constructed.  (Buy concert ukuleles - Thomann online)

At EEB4 students learn ukulele in S1-3 in their music classes. Each year they learn to sing and play more difficult songs. Students who are keen to learn more at home can also buy a ukulele book that teaches songs or technique.
