The birth of the blues harmonica is still unclear (just like the birth of blues music). Ryuga Note: It is generally believed that the musician RIGHTER invented the first diatonic harmonica in the19th century. . Perhaps I accidentally discovered the fact that the harmonica can bend, and then modified it into today's appearance (blues harmonica) to imitate the groans and shouts of Fieldhall. After World War II, black Americans flooded into Chicago, and many blues musicians were born. It is for this reason that Chicago was established as the harmonica capital.

1924, in the first recording of American folk harmonica, unknown musicians played blues music in an improved way. He played the dominant seventh chord as the tonic, such as playing G (that is, the second position, the cross harp) eyuga on the harmonica in C, and most importantly, he found that by changing the mouth shape and the air pressure in the mouth, the sound could be lowered, which is now called bendingRyuga. It has been found that bending is achieved by changing the angle at which air flows through the reed. , thus greatly improving the expressive force of harmonica in music. You can hear the effect of imitating the train in this recording. Ryuga note: the biggest function of bending is to play semitone on the diatonic harmonica, not to imitate the train. Fox chase and other typical blues music.

There is a musician named Howard Levy in America. When he was studying at 1970 Northwest University, he happened to find that the sound of blowing can be blown over, and then the sound of inhaling can also be blown over. This is a big surprise. It took him about three years to finally be able to play three semitones within 8 degrees on the blues harmonica, and he can also play 12 on the harmonica. This makes the musical expression of harmonica more affinity.
