Pucker

Also known as lip block, this is another popular embouchure for playing harmonica. Simply think of blowing and sucking through a straw. Place your lips around the hole (or holes if you are playing chords) and blow or draw on the hole. Also the holes are not as small as they may seem as you have the divisions between the holes to place your lips around.

Pucker

Some people find pucker easier to use to begin with. Myself included. You can open it up to include more notes when playing chords or partial chords. As the tongue is free in the mouth some find this an easier method for learning how to control tone and bend notes down. However when it comes to using techniques beyond this, tongue block becomes more appropriate.

A side note from the Harp-L archives:

4/9/98:
>>Pucker - The lips are pursed and the harp is pushed
>>deep back into the mouth.

>But not as deep as for tongue blocking or U-blocking.  Notice
>the teeth. For pucker and lip-block, the harp is in front of the teeth.
>For [tongue block] and [U-block], it is loosely between the teeth, jaw
>open.
