When you reply or start a new message, right above the message box is a little link in the parenthesis is says (bb code allowed and html allowed) click the "bb code" link. At the bottom is has a youtube embed code. Copy and paste that into the message then copy and replace the youtube address they have in that with the youtube address of the video you want to embed. Simple as that.
I don't play much CA nowadays, but I remember the Bosco Stomp,(version Savoy-Doucet) - was a hard nut to crack, especially the turn. It's a "crooked" tune, with no regular structure, and that makes it extra hard to learn.
This was before I learned from Chris Miller and Dirk Powell, and before there was any method of slowing down. I had to listen over and over again, I wrote down the notes, hummed the tune all day and somehow more or less managed to make something of it on my little 114. I don't think I could play it now!
For you cats dead set on learning the Parlar Trick Perrodin Two Step. Let's take away all the distraction and learn it the same way Steve Riley probably learned it. Let Tony "The Dewey" Balfa play it for you and you can follow on your "D" accordion 1st pozish pushing mostly.
After you get that down, switch to your "C" accordion 1st pozish pushing mostly, and play along with Austin Pitre. Let that loud base beat in the back ground keep you on track and in rhythm. Spend about 2-3 hours with both videos for good muscle memory.
Remember, the Perrodin can be played using only buttons 5,6,7,8. Then you just search for their sister buttons and play doubles whenever you are able or when doubles obviously apply. Persistence pays off. It also helps if there's no one in the same house with you when you begin to learn this song, for they will grow to hate it pretty badly, while you grow to love the way it makes you feel when you play it. Like a great big beautiful PEACOCK! hehehehe.
Just messing around...Tony was that not so famous Balfa that was usually seen beating on Dewey's fiddle with those sticks. Very obscure fellow don't you think? I wonder why?
