Holding a harmonica correctly is essential for playing it effectively. The most common way to hold a harmonica is cupped in both hands, with the left hand supporting the lower end and the right hand covering the upper end.
The left hand should be cupped around the harmonica, with the thumb resting on the bottom edge and the fingers curled around the back. The right hand should be placed over the top of the harmonica, with the thumb resting on the top edge and the fingers curled around the front.
