Harmonica Quesiton?????

Question

What Holes do I blow to get a blues sound on my C harmonica

Answer 1

the ones that make it sound like a C
use your ear holes

Answer 2

Blues harp is usually played in what is referred to as "cross-harp" meaning your key of C harp will actually be playing in G. Also, you'll do way more draw notes than blow notes. Try drawing on holes 1-4 with a few blows thrown in to get a good bluesy sound. Also, you need to learn the skill of note bending to really sound bluesy. Practice on the 2 hole by drawing in and saying "yaw". It takes a lot of practice.
