i recently got a harmonica. its in the key of E. already i find it frustrating that i am winded so quickly and i was told about circular breathing. now in theory it works great an all but when i place my mouth on the harmonica, its not a tight seal so i am unable to pack air in my mouth for use during air intake. i have never played a wind instrument before so these are my first steps with this. any suggestions would be great on proper usage would be awesome and or where i can find some good pointers/tips. i dont want to start out playing the harmonica all wrong and have to unlearn what ive learned cause thats never fun.
