Elements of Music (instruments/chords) How to Listen (song forms & performance routines: blues/A-A-B-A form)


Topics we will discuss and learn:
  • Foundational elements of music: Harmony, Melody
  • Song Forms
  • Performance routines

Foundational elements of music: Harmony, Melody

Harmony is the second element of music.
            The rhythm lays the foundation for which harmony and melody are
laid.  Rhythm is the bones, harmony is the muscle, and melody is the skin.
Harmony sets the structure for the melody and guides the jazz musician on how to approach his improvisation.
Some tunes have a complex harmonic structure
Bebop tried to “separate the men from the boys” and piled on numerous chord changes for musicians to navigate through
Playing tunes with many “changes” requires a sense of comfortability with harmony in order to create interesting rhythms while soloing. 
Soloists may get bogged down in trying to play the changes and neglect developing rhythmic variety.
Some tunes have simple harmonic chord structures so musicians can create their own during their improvisations.
Modal jazz has very few chord changes and musicians are able to play more with their own harmonic ideas.
A sound rhythmic approach is necessary in playing modal jazz in order to keep the music flowing since the emphasis is not on melody or harmony.
            Melody is the third element of music.
Musicians must know numerous melodies along with the chord changes to songs in order play with other musicians anywhere in the world.
They must also be able to interpret the melody so it doesn’t sound contrived
Many musicians take a melodic approach to improvising by creating melodies during their solos.  By playing patterns and scales a musician is outlining the harmonic elements of a song and showing his/her mastery of the tune, but by playing melodically a musician is showing their ability to transcend the original melody of the song and create their own tune on top of the existing one.
Blue notes are the notes that Africans heard in their own music and thus African-Americans adapted the western music they learned such as hymns and folk songs to fit their musical ear.
            The Blue notes are the b3, the b5, and the b7
There is a Blues scale that contains these notes and it is the 1, b3, 4, b5, 5, b7
These notes an the successive scale are used extensively in gospel, blues, R&B, and jazz music.

Song Forms

The most widely used and well-known jazz song form is the blues.
The blues can take several forms but the most familiar form is the 12-bar blues form
            A three bar phrase with four measures each
A statement, a repetition of the statement and then a closing remark
                        My man don’t love me he treats me awful mean
                        My man don’t love me he treats me awful mean
                                    He’s the lowest man I’ve ever seen
           
                                    C7 / F7 / C7 / C7 /
                                    F7 / F7 / C7 / C7 /
                                    G7 / F7 / C7 / C7 /

            The other very popular song form is the AABA form.
One of the most widely used harmonic structures of this form are what are known as “rhythm changes” after the song “I Got Rhythm.”

            A         / Bb   Gmin7 / Cmin7   F7 / Bb   Gmin7 / Cmin7   F7 /
                        Fmin7   C7 / Eb   C#min7 / Dmin7   G7 / Cmin7   F7 /

A         / Bb   Gmin7 / Cmin7   F7 / Bb   Gmin7 / Cmin7   F7 /
                        / Fmin7   C7 / Eb   C#min7 / Dmin7   G7 / Cmin7   F7 /

            B         /  D7    /          /  G7    /           /  C7    /          /  F7    /           /

Performance routines

            During the course of performance there are many events that take place.  Each song is not simply played from top to bottom, there are personalized embellishments that each musician will do
            Intro – the added beginning of song usually 4 to 8 measures in length
Outro or Coda – the added ending of a song usually 4 to 8 measures in length
Shout Chorus – a melody superimposed over the original changes wen the song is played for the last time going to the ending
Trading fours or eights – where musicians alternate soloing for four or eight measures at the end of the solo section
            Stop Time – where the rhythm section breaks behind the soloist
The turnaround or drive – a looped ending of a tune the just keeps on going until the soloist ends it
Turnaround – a two bar section of “dead space” in a tune where musicians add chord changes to fill up the space
Half time – where musicians will slow down the rate of notes they play but the tempo will stay the same.

Double time where musicians will double the rate of notes they play but the tempo will stay the same.
