I have myself, and believe many other members too, often noticed a general misconception as to concertina being a "proper" instrument ( to the layman) or treated with seriousness of say a violin, guitar, flute etc...
There can be the tendancy to dismiss it's many merits!
I have seen people claiming to know about musical subjects, attempt to play one, make a dreadful noise with it! And announce it being " no more than a toy"!
Educating the less informed to see the wonderful diversity of free reed family of instruments, by performing, encouraging, and enthusing them with curiosity has got to be a good thing to aim for; at least I believe.
