Keep in mind that this tablature serves only as a guide and that you must learn how to read music. There are many fingering methods for the Anglo concertina and it’s important that you come up with your own method the earlier the better. Unlike other instruments that need hours of practice like the flute and trumpets which needs breathing exercises and the guitars and banjo that needs to be tuned, the concertina is set to play as it is.
If the bellows are too compressed you will lose air through the chamber and if it’s too wide you will have difficulty controlling the instrument. Rest the instrument on one of your knees and move the bellows with both your arms.
