You can definitely teach yourself ʻukulele, especially during this age of information! Free resources abound, including user-submitted chord charts/tabs, YouTube videos, diagrams, courses, apps, and more! As for paid sources, there are books, online courses, communities, etc. There has never been a time when learning a musical instrument has been this accessible, and there isn't (pretty much) another instrument as accessible as our beloved ʻukulele!
