The difference between jazz and blues lies in their structure, scale, rhythm, harmony, melody and birth.
1. Structure.
Jazz is structurally more rigorous than blues. Jazz is somewhat similar to classical music. Each chapter and section follows certain creative rules. Blues, on the other hand, is more casual than jazz and involves a lot of improvisation. .
2. Scale.
Jazz has jazz scales, such as major bebop scale, dorain, etc. Some sounds are brought about by the introduction of other music fusions, such as flamenco, but the basis is still blues scales.
3. Rhythm.
Swing is commonly used in jazz (the first and second notes in the triplet are connected X-X), shuffle is commonly used in blues (the second note in the triplet on each beat is empty X0X), and swing is continuous. It has what is commonly known as swinging, and shuffle means bouncing and swaying.
4. Harmony.
Compared with the dominant seventh chord in blues, the use of harmony in jazz is much more extensive. Based on the three major chord families, sounds can be superimposed according to personal wishes.
5. Melody.
The unique mixed scale of blues is a mixture of minor blues scale and major blues scale. The three tones are called blues, which gives birth to blues. Compared with blues, jazz has to use thirty or fifty. A scale, or even more than one, these scales are called modal scales.
6. Birth.
Blues is an original music created by black people and originated from the black community. It is the most basic foundation of black pop music, and it is also the beginning of rhythm and blues. However, Sir Sir was born in the lower middle class, but served the upper class.

Although the lead singer is the focus in blues music, the improvisation of guitar-based instruments is also very exciting. Instrumental players can transcend the boundaries of chords and play as they please. In addition to the melancholy sound of the melody, it also includes the sounds of a knife being scraped and a slide being used, as well as a humming imitation of the lead singer.
Blues is a kind of vocal and instrumental music based on the pentatonic scale. Another feature of it is its special harmony. Blues is a singing form that emerged among black folk after the Civil War. It has a direct relationship with black plantation songs (a cappella songs sung by collectives during labor). Blues originated from the hymns, hymns, labor songs, shouts and chants of African American slaves in the past.
With the development of blues music today, it has been included in the ranks of mainstream music, and many of its elements are increasingly used in rock and pop music. But traditional blues music still has great strength.
