Comparison of blue harmonica and other harmonica
Mar 24, 2018

Compared to the chromatic harmonica, the blue-tone harmonica is arranged in a diatonic scale. Players can perform partial semitones through the technique of pressure. There are also some performers who can use the tone-raising technique of the blues harmonica to create more halftones and compensate for all the chromatic octaves within three octaves.

 

The reason why it is called a blue harmonica is because the most widely used genre of the instrument is the blues, which is one of the important traditional instruments in the blues. So how is it different from other harmonica? Below to understand the specific content.

 

First of all, there are obvious differences in the hardware structure design. For example, in the ten holes of the blue tone harmonica, each hole (each air chamber) has one blow and one suction reed. In the harmonica, copper corners, Bass and other harmonica, there is only one reed in the air chamber that blows or inhales. The chromatic harmonica is independent of each other due to the keys and the film. That is, there is only one reed in one air chamber.

 

For the blue harmonica, the blowing and sucking reeds in the same air chamber can have an interactive effect, so that the unique pressure effect can be played.

 

Secondly, blue tone harmonica and other harmonicas also have some differences in the arrangement of the scales and the notation of holes. It only has natural sounds in diatonic scales. There are three octaves in the range, and there is a lack of sound in both the bass and treble, but the lower part repeats inspiration 5 (Sol). In addition, a variety of different hole notation methods are widely used, and at times they are often marked with staves or notations to indicate time values.

 

In addition, the playing characteristics of the blue harmonica are also very prominent. This kind of harmonica has considerable imitative power in the process of playing. It has a melancholy gracefulness. At the same time, the unique sound pressure technique makes the blue tone harmonica distinctive, so it is suitable for blues, rock, country, folk, jazz and other styles.
