avoiding buzzy "dinky" strings ,

ok to avoid the "dink"
make sure the fingers press the strings with the tips so the fingernail is looking up at you .
keep the finger as close behind the fret barre (the metal strips on the neck ) as possible without touching it .
thumb at the back of the neck quite far down for notes which are extra "dinky "
don't "over grip" find the right amount of pressure for the string to make contact with the fret barre by pressing the finger and the thumb towards each other then rest .
