How can harmonica play the vicissitudes of cowboy style in the west? Mine is a 10-hole harmonica in C, and music is better.

Usually, the feeling of vicissitudes is often low. The piano sound in C major is a little high, but if you switch to the second one, this is the sound in G major you play. The second position of the ten-hole harmonica is mainly due to the inspiratory sound of the two holes, and then it is arranged in the major scale. The blues are very vicissitudes. You can try to practice this music, and of course you can improvise. The general rule of improvisational blues in C major is to use the second position. The broken chord of G7 chord is used as the main chord, and then its subordinate chord is used to advance the process of music. After the subordinate chord is solved, it returns to the main chord, which is generally three segments of 12, and the rhythm of 4/4 and 8/ 12 is commonly used.
