There are no hard and fast rules with respect to choice of key.
For a triple row, the 1st choice is F-Bb-Eb. This is the most common nowadays. In the past, G-C-F was more common than it is now.
For single rows, Bb is typically regarded as a better choice than C if you play to play zydeco, while C is regarded as better for Cajun.
Having said that, a huge factor in the choice of key is to get an accordion that will fit your vocal range. There is not much point in buying an accordion which requires a tenor range voice, if you happen to be a baritone. This is my situation. There is just no way that I can hope to hit a high G when I am singing; even a high F can be a challenge if I don't do everything just right. If I was to use a C accordion, I would be playing a lot in G, and I would not be able to hit that note. So, I use a Bb box. Same thing with the triple row: F-Bb-Eb is more accomodating to my voice.
A real cajun accordion is a 10 diatonic (maybe 9)button accordion (works like a mouth harp/ harmonica). Just look at the pictures on the web. If you decided to go for one, buy a good one or a used second hand (good) one. It will make you happy and it will keep its price. members on this form will advice you. I myself own 2 LA handmades of two different brands (and different keys, C and D)and am very satisfied with them.
When I first got the desire to play back in 1985, my dad gave me what I thought was some sound advise. He said unless I absolutely knew for a fact that I would be committed to playing it made no sense to invest in an expensive accordion. So, I bought an el cheapo for 200 bucks and practiced on it. After about 6 months the desire was still there only stronger.
I then invested in an ACADIAN, and WOW, I thought I'd died and gone to heaven. What a difference!
Thats more like 3 cents. Anyway, good luck with whatever you decide and with your playing.
Do NOT get a Chinese box! I am a newbie, purchased a Hohner Ariette in January of this year from Ebay $269. Big mistake and waste of money. Too hard to play, sounded awful, extremely poor quality. I purchased a slightly used Bon Cajun in June that I found through this site and have been happily playing every day since then. Even though I am only a living room 'musician' at this time, it was well worth the money. My advice, spend a little extra and get an LA or TX handmade(I have been paying attention), you will not regret it. And the best thing you have done is find this site. I thank all of you for the great information I get from reading your posts.
Wow, what a lot of great responses. Thanks to all of you!
I tend to agree with Carol. As I mentioned, I play other instruments, and I know that a cheap, poorly-made instruement is much more difficult to play than a quality piece, not to mention that quality also will sound a whole lot better. I think that maybe a lot of aspiring young musicians may be discouraged from continuing in their musical endeavor when they find out how difficult it is to learn one. Making it more difficult with a cheap instrument is not a good thing.
As said on here, I think a good box is a good "investment", both monetarily and musically.
I'll keep reading here, keep looking in the pawnshops and ebay, and keep my eyes open for a nice LA or TX box. Is there a particular website anyone recommends to go to and read up on specifically what to look for, how to recognize them, etc.
Finally, one more question: How about a piano accordion? I don't know enough about this genre of music to know if you can get a good cajun or zydeco sound from a piano accordion. Can it be done?
would it be much more difficult to do (play the notes) on a piano than on a diatonic? (I already play the piano, so fingering would not be an issue).
The piano accordion once ruled the roost in zydeco. It's still a rockin' instrument though!
Check out CDs by Corey Ledet, Lil' Nathan, Curley Taylor, and Lil' Brian & The Zydeco Travelers for some new school mastery. In the old school, you probably already know about Clifton Chenier! But there's also C.J. Chenier, Buckwheat Zydeco, Nathan Williams, Wilfred Chevis, Leon Sam, and Lynn August just to name a few.
