One little comment about the popular 10 key diatonic and key. The key of the diatonic scale of the harmonica is indeed stamped on the the harp. However if you are playing "blues", the common technique, called "cross harp" compels you to play a harp tuned for a perfect forth above the key in which you are playing. So if you are playing the blues in C, use an "F" harp. With this method the natural notes of the blues scale are more abundant and the bendable notes are the right notes to bend for the blues. Good luck.
