I worked from a couple of different book/tape combinations, the Klutz set "Blues Harmonica for the Musically Hopeless" by Jon Gindick, and "Country and Blues Harmonica" by David Harp. But I didn't really go anyplace with it until I started playing with records in the 4th key harmonica for the key the number was in: C for G, G for D, D for A, A for E, and so on (the Bb and the F mentioned above are for F and C--although you can get another couple of keys out of each harp, these combinations give you the most musical flexibility. So sit down with your C harp, play along with your friend on a tune in G, emphasize the draw notesx (starting with 1,2,3,4 holes) for the G chord, the blow notes for the C chord, and the 4 and 5 draw notes for the D7 chord. You can also, of course, play along with your favorite CDs if you can work out the keys the songs are played in. This is especially good--just set your player to repeat and you can drive your family crazy by playing the same song over and over for a couple of hours. After you've got the basic harmonic structurew down you can start trying to bend notes (moving your tongue to increase the volume of air in your mouth) and pick up other techniques, such as tongueing, using your hands for a wah-wah sound, etc.Just listen to yourself a while and it'll all make sense--but if you need additional help, try one of the above courses (both John Sebastian and David Harp have lessons on video as well as tape)(and what is it about harmonica teachers and CDs, anyway--I bought Charley McCoy's Blues and Country Harmonica course and it was the same thing, no track stops.
