Here are a few thoughts when playing a song like Perrodin 2 step.
Of course, start with a full bellows (bellows open) because you're going
to need lots of air!
Note that the chord pattern for the first phrase is |C|C|G|C|.
So, you'll be pushing the bellows closed for the first 2 measures,
then opening it for 1 measure, then closing again for 1 measure.
When you come to that "G" chord, and you're on-the-pull, open your
air regulator button as you pull to get the bellows all the way opened again.
Also, the slower the song is played, the longer the notes are sustained
and therefore, more air is used up more quickly. It requires less air as
you learn to play at a more rapid tempo.
Be sure you have no bellows leaks that will rob you of reserve bellows power.
And, if you have a lower priced accordion, the reeds may not be efficient,
and require even more air to make them "sound'.
Lastly, a lower key accordion such as "A" will have larger reeds than a
high pitched accordion like an "F" and will require more air to sound.
Hello Big,
I have a Cajun accordion manufactured by G. Miller in C. When I push the bellows without pressing any key, it will fall almost without resistance so for me it leaks.
I worked with your Perrodin two step method 3, I saw the work the bellows and with my accordion I not complete the measures do from lack of air.
thank you for your answer
