My harmonica lessons are all about you developing your ability to breathe.
I think my method is one of the best on the planet for helping people learn how to regulate air flow and to develop diaphragmatic breathing.
At this point it is common for hospitals to bring in harmonica programs to help people recover from these ailments. I believe in addition to helping you learn to breathe, the harmonica will bring an element of fun into your life and focus your mind on making the best out of a very challenging situation.
Please do check with your doctor / health care professional first.
