Before we can improvise using the chord
tones of various seventh, we must know those chord tones. My previously
posted video entitled Learning
Music With Ray: Seventh Chords, helps to explain the various types (qualities) of seventh
chords, how they are formed and how to derive their pitches. To improvise
using these pitches, we must obtain the ability to rapidly recall and perform
these pitches at will. The following exercises are designed to help
achieve that ability.
In this first exercise, the pitches of
each seventh chord are arpeggiated up and back down by starting on the
root. Every key is covered by ascending through the keys in half-step
increments. The exercise is illustrated with major seventh chords, but it
can be applied to any type of seventh chord.
In this exercise, the pitches of each
seventh chord are arpeggiated down and back up by starting on the root.
Every key is covered by descending through the keys in half-step
increments. The exercise is illustrated with major seventh chords, but it
can be applied to any type of seventh chord.
In this exercise, the pitches of each
seventh chord are arpeggiated down and back up by starting on the root.
Every key is covered by descending through the circle of fifths. The
exercise is illustrated with major seventh chords, but it can be applied to any
type of seventh chord.
In this exercise, the pitches of each
seventh chord are arpeggiated up and back down by starting on the root.
Every key is covered by ascending through the circle of fifths. The
exercise is illustrated with seventh chords, but it can be applied to any type
of seventh chord.
In this exercise, the pitches of each
seventh chord are arpeggiated up and back down by starting on the third.
Every key is covered by descending through the keys in half-step
increments. The exercise is illustrated with major seventh chords, but it
can be applied to any type of seventh chord.
In this exercise, the pitches of each
seventh chord are arpeggiated up and back down by starting on whichever pitch
exist in the lowest part of the instrument’s range (demonstration written for
saxophone). The point is to challenge the player with random seventh
chord inversions. Every key is covered by descending through the circle
of fifths. The exercise is illustrated with major seventh chords, but it
can be applied to any type of seventh chord.
In this exercise, the pitches of each
seventh chord are arpeggiated down and back up by starting on whichever pitch
exist in the highest part of the instrument’s range (demonstration written for
saxophone). The point is to challenge the player with random triad
inversions. Every key is covered by descending through the circle of
fifths. The exercise is illustrated with major seventh chords, but it can
be applied to any type of seventh chord.
In this exercise, the pitches of each
seventh chord are arpeggiated up and down in straight paths that extend through
the full range of the instrument (demonstration written for saxophone).
The direction of the arpeggio remains constant (through multiple chords) until
the end of the instrument’s range is reached. The point is to create
fluid lines across multiple triads, using the full range of the
instrument. Every key is covered by descending through the circle of
fifths. The exercise is illustrated with major seventh chords, but it can
be applied to any type of seventh chord.
In this exercise, a simple pattern is
created by arpeggiating through the 2-5-1 progression. The exercise arpeggiates up the ii7 chord,
starting on the root. It then arpegiates
down the V7 chord starting on the 3rd (the closest pitch coming down
from the last pitch of the ii7 chord).
Finally, it arpeggiates back up the Imaj7 chord starting on the root. This exercises cycles through all the keys by
converting the root of the I chord at the end of the progression into a ii7
chord for the next progression. This
pattern will cycle through 6 of the 12 possible keys.
The cycle can be repeated with a starting key
that is half a step higher in order to cover the other 6 possible keys.
The musician should start with a simple
applications like this, and then create more complex arpeggiated patterns. The ultimate application is to create a free
form musical improvisation that only utilizes the pitches of each seventh
chord, and outlines the chord changes of the progression.
The final way to practice chord tone based
musical improvisation with the use of seventh chords is to apply the above
exercises to the chord structure of an actual song that contains seventh
chords. For example, we could arpeggiate
each seventh chord of the song up and then down starting on the root. Instead of applying a half step or circle of
5ths progression to change chords, we merely apply the exercise to the chord
changes of the song. When the beat
duration of a given chord limits the amount of material that can be played, we
modify the arpeggio pattern (example: only go up the arpeggio instead of going
up and down).
