Also known as, "America's classical music", characteristics of jazz include the following:
- Strong beats or rhythms (often syncopated);
- Sad tones or blue notes;
- A swing element (playing of triplets);
- A call and response element (a musical phrase is echoed by different instruments or human voice);
- Unique, individualized style of the musicians; and,
- Major emphasis upon spontaneous improvisation (using the harmonies of a composition then creating a spontaneous melody line).
History of Jazz
Where the actual name of jazz originated - who knows?
From the plantation fields of southern American slaves, work and misery produced the call and response element known to jazz. A leader during a work regime might call out a melodic line to be answered by the workers.
Additionally, the African-American spiritual, capturing the drudgery of the plantation fields and all of the agony experienced by a people once considered less than human, provided another root to the jazz genre.
Ragtime
Then emerged ragtime (highly syncopated) and the blues, two more foundational blocks to modern jazz. Scott Joplin (1867-1917), pianist/composer, famous for his rags which embodied not only the African-American elements but some European enhancement from Irish gigs, German waltzes, and French quadrilles.
His rag, The Entertainer, adapted by Marvin Hamlisch, provided the foundation for the musical score to the movie, The Sting, 1973 (Starring Robert Redford and Paul Newman).
The Blues - Blue Scale
The blues scale converts a major scale, for instance in the key of C Major, CDEFGABC, the E, lowered a half tone, becomes Eb, the G becomes Gb and the B, Bb. These lowered tones produce the "blue" sound characteristic of musical pieces known as the "Blues". Blues music not only uses the blue notes, but is generally 12 bars long in a 4/4 count.
Additional foundational jazz style blocks include, Dixieland, Big Band (swing), Bebop and Free Jazz.
What is Syncopation?
Music has beats. When there are four beats in a measure (like four quarters to a whole), there are strong and weak beats. For the measure containing four beats, the first and the third beats are the strongest.
Then there are the half beats, in between the whole beats. For instance, if counting the beats, one would count: one and two and three and four and. When the weaker beats (two and four) are emphasized, or, the note is played or held over on the "and" of the beat, there is syncopation.
What is Improvisation?
Musical compositions are written using harmonic progressions. Given the specific scale used, a chord is built from the root note. For instance, using C Major again, C is the first note. A chord can be built from that note which would include, CEG and B. Doing the same for each note of the C Major scale and then placing them in an harmonic progression, a new, spontaneous melody line is created. This takes practice. The more practice, the easier it becomes.
Improvisation refreshes old musical compositions. This technique keeps the piece new and vibrant as well as distinguishes the performing soloist.
Improvisation is not magical. The well practiced/trained jazz musician hears the chord progressions/musical phrasing and melody in his/her head. There's a great deal of skill involved.
In America, where so many cultures converge, the tentacles of music exist, binding us all together.
