It wasn't me that said that, but to answer your question anyway, I think what was meant was that during the course of the dance a switch was made from one accordion to another, not during a particular song (e.g., play 10 songs with a C accordion, then play the next 10 on a D).
However, I know of cases where a key change was made in the middle of a song. One scenario involves a quick accordion switch, perhaps while another instrument is soloing. Another scenario is when a dual key accordion is being used - i.e., a Randy Falcon accordion, in the hands of Wayne Toups: push down the 3 stops for one key, and pull up the 3 stops for the other key and off you go.
Re: Re: Characteristics of certain keys - from a classical music perspective.
I have heard the same thing from classical performers. However don't forget
Hank William's "Kawliga" did the same thing in that it changed from a minor to a major key and really has an effect. It really gives a lift to the music.
Re: Re: Re: Characteristics of certain keys - from a classical music perspective.
Also .. an additional observation ..
The thing with Kawliga is that it did not change
to a relative minor key, such as going from
"C" to "Am", but instead just changed to a minor
key (such as going from "C" to "Cm")
which is probably impossible to do on a
i play in many keys, in the band repertoire
on the c accordion they would be
A [really A7 - the band plays in A
but of course my 3rd and 7th are flatted,
a very bluesy key]
and most of them on both C and Bflat accordion
and some on G, Bflat or F rows of my 3 rows
so it makes for a lot of key variation
then i'm playing zydeco, it;s not quite
as stuck on the first and second positions
