So far you have learned about playing in first position, and second position (cross harp). It is also possible to play in another key in what is known as third position. This sound is often associated with minor keys. On the C harmonica, third position can be used to play in the key of D minor. The key note for third position can be found at holes 1, 4 and 8 (a D note). It is important to memorize where these notes are as soon as possible. The following example demonstrates a chordal riff played in third position.
