Since I guess it's impossible to hijack your own thread, let me add a couple of accordion tidbits for you guys. dadt mentions Cajun music. They most of the time use button or diatonic accordions, which don't have the piano keyboard. Same goes for the Norteno music of northern Mexico and the other genres of Mexican music that use accordion. Those guys use little diatonic (built specifically in a music key) accordions. When you push in on the bellows, it's one note, and when you draw on the bellows, it's another note, much like a harmonica, if you guys have ever experimented with those. Mexican players usually remove the bass reeds entirely from their instruments, as they don't play the bass part most of the time anyway. The accordion model you see here is a Stradella bass accordion, which means you have single notes and various chords, like major, minor, dominant 7th and diminished chords you can play in the bass, so there are lots of things you can do to accompany a melody in the right hand. Pretty cool, really. The accordion model you see also plays the same note for a given key or button whether you are drawing or pushing the bellows. My accordion sounds like a large organ when all the reeds are sounding at once. Those little accordions in Cajun and Mexican music often has what's called a "musette" sound, and they like that specific quality in their music. It doesn't sound like an organ, and some reeds are purposely tuned offkey a bit to create sort of a vibrato sound. Pretty stuff, kind of like a French cafe. Your dose of trivia for the day. More on the model this afternoon. Thanks for all the input.
