A subtle art form, jazz improvisation calls for a deep knowledge of harmony, melody, and rhythm. A great way to improve improvisation abilities is the employment of enclosures. With a thorough examination of enclosures and their relevance in jazz, this all-encompassing manual offers a set of drills to enable players to include this approach in their music.
Understanding Enclosures
An enclosure is, by jazz definition, a melodic device in which a target note is immediately approached by the environment of its neighboring pitches, whether chromatic or diatonic. The tension and subsequent release thereby created an aid that imparted a sense of motion and sophistication to the solos.
Types of Enclosures
Chromatic Enclosure: Chromatic enclosures are approached using chromatically adjacent pitches. Hence, targeting G means climbing to it via F#, G#, and G.
Diatonic enclosure: This uses notes from the key in order to approach its final target. So going into the note E in C major might mean playing D, F, and then E.
Double Enclosure: This includes any combination of either approach from above. For G, that might mean F, G#, F#, and then G.
The Importance of Enclosures in Jazz Improvisation
Enclosures have numerous functions in jazz improvisation:
Melodic Interest: They complexify, therefore keeping the surface interested, if not active, far past the simple scale runs.
Voice Leading: Enclosures extend the line between floor and ceiling, creating enhanced continuity in harmony.
Rhythmic Variation: They inject elements of syncopation or unexpected accents into the rhythmic content of the solo.
Exercises to Master Enclosures
Use practice for Enclosures incorporated into your playing. Here are exercises designed to develop proficiency in enclosures.
Exercise 1: Chromatic Enclosures Accessible to the Major Scale
Final Objectives: All chromatic approaches to each note in the major scale will be known.
- Select a major scale (for example, C major).
- For every note of the scale, play the half step below the note, a half step above the note, and finally the target note, for example:
Target: C | Play: B, C#, C
Target: D | Play: C#, D#, D
- The pattern continues along the scale.
- Ascending and descending the scale, practice this exercise.
Exercise 2: Diatonic Enclosures within the Major Scale
Objective: Apply each scale degree to diatonic notes.
- In the chosen major scale, for every note, play the diatonic note below, the note above the target, and then the target note. For instance, in C major:
Target: E | Play: D, F, E
Target: G | Play: F, A, G
- Continue this pattern through the scale, both ascending and descending.
Exercise 3: Enclosures Targeting Chord Tones in a II-V-I Progression
- In this lesson, we are going to regard Dm7 (II), G7 (V), and Cmaj7 (I) as jazz standard chords forming the most used of all progressions, namely, the II-V-I in C major.
- Identify those chord tones for each chord.
- Now take up some chromatic enclosures on each of those chordal tones. Here are a few examples:
Dm7: Target F | Play E, F# and F
G7: Targeting B | Play A#, C, B
Cmaj7: Targeting E | Play D#, F, E
- Practice this over the progression with emphasis on the smooth transitions from one chord to another.
Exercise 4: Enclosures in the Blues Scale
Aim: To apply enclosures in a blues setting.
Pick any blues scale (for example, C blues: C, Eb, F, F#, G, Bb).
- Apply chromatic enclosures to each pitch of the scale. For instance:
Target: C | Play: B, C#, C
Target: Eb | Play: D, E, Eb
- Use these enclosures for your improvisation over the 12-bar blues patterns to extend the depth for your solos.
Exercise 5: Bebop Scale Enclosures
Aims: To apply enclosures over the bebop scale to achieve Jazz’s perfect glow.
- Pick a bebop scale (such as C major bebop: C, D, E, F, G, A, Bb, B)
- Now apply chromatic enclosures along with some cleared chords on each note. For example:
Target: E | Play: D#, F, E
Target: G | Play: F#, G#, G
- Practice them over various rhythmic patterns to get into the bebop feel.
Advanced Application: Enclosures over Complex Chord Progressions
Since you have established the essential enclosures, strive now to work on super-stimulating musical progressions and tempos.
Choose a jazz standard with intricate chord progressions (such as “Giant Steps” by John Coltrane).
Pick out key chord notes in a progression.
Now, figure out the right kind of enclosures on these chords. Looking at both chromatics and diatonics would be helpful.
- Keep in slow, increasing tempo while you build ease.
- Integration of Enclosures in an Improvisation
- This is how the whole enclosure thing is made to be a seamless entity within a larger solo:
Transcription: Audition solos of jazz masters, with a note toward their use of enclosures. Transcribe and scrutinize those sections to fully grasp how they are applied.
Composition: Compose melodies and solos including enclosures, focusing each time on creating interesting harmonies and logic of melodic development.
Rhythmic Variation: An interesting rhythmic augmentation by using a variety of rhythm placement for enclosures, such as starting on the offbeats or involving triplets.
Conclusion
The art of enclosure master is much beloved as doing so for jazz improvisation opens up melodic lines with great depth, sophistication, and fluidity. Furthermore, with chromatic and diatonic enclosures combined, they can make solos more expressive, voice lead better, and achieve mastery over their harmonics.
What would help players in getting the method thoroughly internalized would be structured practice of some sort; beginning with literally scale-type-enclosures, including uses with chord tones before building up to the extent that they would include real jazz standards. These would include things like studying transcriptions, composing original phrases, and experimenting with rhythmic variations on the improvisational vocabulary.
Regularly practicing the exercises found within these pages, in conjunction with seeking out additional resources, can elevate musicians’ abilities toward creating solos in an even more appealing, authentic manner. First-timers with regards to phrasings and those who have gone very far in building articulation techniques would find that enclosures are critical in developing a more mature and vibrant jazz sound. Keep practicing, keep creative, and let enclosures release more territory in your improvisation!
