I think it's asking a bit much to expect us all to agree on what "hybrid" means in this context given that there isn't a foolproof workable definition of "concertina" that we can all agree on either.
That's a part of what I've been trying to say.
I remember when I first heard (or read) the word "hybrid" to describe the new breed of concertinas and being unhappy with the term, although I don't remember why.
Maybe because it was too vague?
In any case, one important (to my way of seeing it) characteristic of the instruments we call hybrids that I don't see mentioned here is price intermediate between the cheapies and the real deals.
Earlier in this thread, I wrote:
...These "hybrids" we talk about are also commonly referred to as "accordion-reeded" or as "mid-range" (in price, and possibly in quality)....
It might be said that if we call it a concertina and it costs between $1200 and $3000 new then it's a hybrid, no matter how it's made.
. It's not a "hybrid", it's a "macaroon"! I'm sure that the fact that the word "macaroon" represents particular dollar amounts is obvious to a newcomer here -- or even an old timer, -- while the arbitrary convention that a noun meaning "mixture" designates a particular price range is not
OK, sarcasm aside, I think that a term used to denote a particular class should be somehow descriptive of that class, and certainly not
a word that denotes a completely different characteristic, even if the two happen to be loosely correlated at the present moment.
David, if it's price range you want to denote, then "mid-range" is a perfectly good term, and one that has been in common use here on C.net in the past. I still use it. "Mid-priced" might be even clearer.
