It'll be a fun introduction to a great folk instrument!

Honestly, if you're like me and you didn't know if the concertina was a good instrument for you, go ahead and buy one of these

and I would probably like to get a better instrument one day once I've learned on this one (it's my first concertina)

When I bought this, I started learning and quickly realized that in order to progress further in skill, I would need to upgrade to a better crafted instrument

The concertina is not exactly a cheap instrument, so I am thankful that low end models like this exist to help you decide if that investment will be worth it
