Watch the Holding the Harmonica online guitar lesson by Annie Raines from Blues Harmonica Blueprint
There is more than one way to hold a harp. I hold it in my left hand (with the numbers on the top) to create a cup around the low notes where most of the shaping goes on. Many of my left-handed students prefer to hold the harp in their right hand, freeing their dominant left to move and create the "speechifying" effects. In order to maintain a cup shape around the low notes, some of the great left-handed players also played the harp upside-down with the numbers on the bottom.
