This is very true. To initially open the bellows a bit to play in the dominent key of the accordion....d,c,bflat, whatever, is important.

although, i find that starting a song on the pull position, or second position at the very start of the song, the air regulator is not needed.

I mean, AT FIRST, I STRESS AT FIRST (but the air button is needed more-so throughout the rest song on the pull position than if it is a song based inititally in the push key or first position).

The air regulator is needed even more so but again, slightly used correctly, in the third position

jim p,

you make it sound as if using the air
regulator can harm the accordion.

please advise..

i don;t see how it could..

wle.

I'm not sure i know what you mean. the air regulator does not hurt the accordion. Are you joking with me?

ok, i may have misunderstood when
you advised 'only slight tapping of the regulator'.

i thought you were saying, "never keep it press for a
long time"

wle.

Sorry for the misunderstanding. I meant never press it for a long period of time for it will hinder your ability to play. It's like having a huge leak in your accordion
