The Specific Rhythms in Mike Longo’s “Rhythmic Nature of Jazz”

Overview of Jazz Rhythmic Concepts

Mike Longo’s approach to rhythm in jazz is deeply rooted in polyrhythms, polymetric time, and the “melodization of rhythm.” His studies reveal how African rhythmic principles shape jazz and how bebop’s rhythmic behavior creates deeper swing and feel. Below are the core rhythmic elements extracted from his teachings.

---

I. The Concept of Polymetric Time

• • Jazz time is polymetric, meaning multiple meters exist simultaneously.
  • Longo demonstrates how a 6/8 pattern can be felt in different meters (3/4, 4/4, 12/8, 5/4) depending on accent placement and phrasing.  I also present the interrelationship of each of these meters in this video.
  • Example: A musician can play a groove in 6/8 but mentally shift their perception to different meters, altering their phrasing and accents accordingly.
  • Key Exercise: Play a steady groove in 6/8 while consciously shifting your frame of reference to feel it in:
    • 3/4: Shift from 123456 to 1&2&3&
    • 12/8: Maintain a triplet subdivision and hear the groove as 1&a2&a3&a4&a
    • 4/4: Shift from 12/8 (123456123456) to 1–2–3–4–
    • 5/4: To feel 5/4 within 6/8, subdivide the pulse into a 3+3+2+2 grouping. Start by tapping quarter notes in 6/8, then emphasize the downbeats of the 3+3+2+2 structure. Once comfortable, try clapping the 5/4 rhythm while keeping a steady foot tap in 6/8. Another approach is to count cycles of 10 eighth notes (spanning five beats in 5/4) over a two-bar phrase of 6/8.  This can be tricky so check out my YouTube video on the subject.
  • Practicing this exercise trains rhythmic flexibility and strengthens the ability to hear and feel multiple time signatures at once.

II. Bebop and the “Hidden Five”

• • Dizzy Gillespie’s “perfect offbeat” concept: The offbeat in jazz is not simply “&” but a new “1” when a note event occurs.
  • 5/4 as a rhythmic foundation in bebop cymbal beats:
    • Longo suggests that bebop ride cymbal phrasing evolved from 5/4, specifically using a 3+3+2+2 subdivision.
    • He maps 5/4 (as 10 eighth-note triplets) into 6/8 and then into 4/4:
      • 5/4: |1–&–4-5-| (10 eighth-note triplets)
      • 6/8 interpretation: |—chip-a|ching–chip-a|
      • 4/4 transformation: |———–ba| oo ba da oo ba da oo ba da oo ba da| where the ‘da’ accents the 3rd part of the triplet of each beat as in – – a – – a – – a – – a
    • While this claim may be somewhat speculative, practicing it can deepen one’s awareness of the interrelationship between 5/4, 6/8, and 4/4.
  • The “Hidden Five” Concept:
    • The “hidden five” is derived from playing a 5/4 rhythmic cycle within 4/4 time.
    • The core 5/4 rhythm is expressed as x-x-xx-x-x, structured as two sets of ta-ge-ka:
      • Ta-ge-ka, ta-ge-ka (two triplets per measure, making 10 eighth notes in total).
    • To integrate this into 4/4, start the phrase on the “a” of beat 1 in 4/4:
      • |–a-&-3&-4-a|1
    • Key Exercise:
      • Count in 1–2–3–4– or 1&a2&a3&a4&a, then scat the rhythm:
        • |–a-&-3&-4-a|1 or |–ta-ge-kata-ge-ka|ta
      • This primes the ear to hear the 16th-note triplet that follows:
        • |——-&-4-a|-&a2-a3-a4-a|

  Practicing this rhythmic transformation helps musicians develop a deeper internalized sense of swing and cross-rhythm phrasing.

III. Additive Rhythm, Hearing Swung 4/4 Lines in 6/8, and Continuities

Additive Rhythm

Jazz rhythms are often structured in additive groupings rather than conventional subdivisions. This approach, drawn from African rhythmic traditions, helps musicians internalize syncopation and polyrhythms more naturally.

• Example: Manteca Bass Line
  • Standard counting: |1 2 (3) & &| (1 2 3) & &|
  • Additive rhythm approach: 2 + 3 + 2 + 4 + 2 + 3
  • Breaking it into smaller groupings helps keep the groove without losing precision.
• Key Exercise: Practice counting using additive groupings rather than strict subdivisions. For instance:
  • Count “taka taka takida takida takida takida” instead of 1&2&3&4& to internalize the feel of syncopation.
  • Use syllables like “takida” (3) and “takadimi” (4) to feel rhythmic flow naturally.

Swingifying Standard Melodies in 4/4 Using 6/8 Feel

Traditional 4/4 swing notation can be misleading because it fails to capture the triplet-based feel of jazz. A better approach is to reframe swing phrases in 6/8 or 12/8, making the rhythmic placement clearer.

• Example: Charlie Parker’s “Confirmation”
  • Standard 4/4 notation: |1&-&3&4&a|1&2&3&-&|-& |
  • More accurate rhythmic representation in 6/8:
    • 6/8: |1-3–61-3456|1-34-61-3–6|–3 |
    • 12/8: |1-a–a3-a4&a|1-a2-a3-a–a|–a |
  • Once musicians begin hearing swung eighth notes in this framework, it fundamentally changes their perception of jazz phrasing.
• Key Exercise:
  • Take a simple swing melody and rewrite it in 6/8 or 12/8.
  • Sing or play it using triplet-based phrasing rather than strict eighth notes.

Continuities

Longo emphasizes the concept of rhythmic “continuities,” where rhythmic ideas develop naturally through displacement and overlapping pulses. This leads to a deeper sense of swing and time.

• Example: Quarter Note Triplet Displacements
  • A quarter note triplet starting one eighth note into a measure
  • Another starting one sixteenth note into a measure
  • These slight shifts in rhythmic phrasing create deeper swing and groove.
• Key Listening Examples:
  • Chick Webb playing Benny Goodman’s “Stompin’ at the Savoy” (Fletcher Henderson arrangement)
  • Mike Longo’s album with Lewis Nash & Bob Cranshaw
  • Longo’s composition “Checked Bags”
• Exercise:
  • Play quarter note triplets starting at different points in a measure.
  • Experiment with how they affect swing feel by shifting their placement forward or backward slightly.
  • Try: |- x -|x – x|- x x|x x x |

Mastering these rhythmic elements expands a musician’s ability to manipulate time freely, making jazz phrasing feel more organic and fluid.

IV. The “Dizzy Triplet” and Displaced Time

Ray Brown Triplet

Ray Brown introduced the concept of half-note triplets that begin after an eighth note or eighth-note rest. These triplets shift the rhythmic placement of phrases, allowing musicians to enter a steady flow of time rather than consciously trying to keep time.

• Key Insight:
  • A student noted that once he started playing this triplet, his accents “chose themselves”—meaning he was no longer forcing the rhythm but instead experiencing the natural flow of time.
  • This highlights the importance of understanding the source of a musical phenomenon rather than simply imitating its effect. Charlie Parker’s lines, for instance, came from a specific rhythmic process—so learning how he played is more valuable than merely replicating his notes.

---

Dizzy’s 8th Note Triplet

Longo’s rhythmic approach involves thinking of quarter notes in 4/4 as dotted quarter notes due to their connection to 6/8. This changes how rests and subdivisions function within a phrase.

• Key Concept:
  • A dotted eighth note is half of a dotted quarter note.
  • To play the Dizzy triplet accurately, musicians should visualize 3 against 4, shifting the triplet’s placement.
• Step-by-Step Exercise:
• 

Practicing this approach trains the ear to recognize displaced rhythmic phrasing, a key element of bebop time-feel.

---

Dizzy’s 16th Note Triplet

Dizzy also applied this rhythmic displacement concept to 16th-note triplets, taking the same concept further.

• Key Exercise:
  1. Start by playing the triplet as an 8th-note figure.
  2. Gradually increase speed until it transitions into a 16th-note triplet feel.
  3. Maintain continuity—once the triplet starts on an 8th note, the second beat lands between the 2nd and 3rd triplet divisions.
• Visualization:
• Application:
  • When applied to bass playing, it enhances the rhythmic “pocket.”
  • A bassist noted that playing the triplet resulted in a strong backbeat on 2 and 4, reinforcing swing feel naturally.

Mastering the Dizzy triplet enables musicians to access a more fluid, swinging time-feel, allowing rhythms to breathe and evolve within phrases.

V. Ultra-Advanced Exercises

• Con Alma and Displaced Half-Note Triplets

  Longo’s most advanced exercises incorporate displaced half-note triplets, shifting the time feel while maintaining a strong rhythmic foundation.

  • Key Concept:
    • This figure, based on Con Alma, features half-note triplets that are displaced by an eighth note.
    • The displacement creates a unique phrasing that floats over the pulse, requiring a strong internal sense of time.
  • 
  • Exercise:
    1. Play standard half-note triplets over a 4/4 groove.
    2. Displace the triplet figure by an eighth note, shifting its rhythmic placement.
    3. Improvise while maintaining the displacement, ensuring the groove remains steady.

  ---

  Final Exercises: Polymetric Variations

  A further variation on the same Con Alma chord changes introduces a more complex rhythm.

  • Key Rhythmic Structure:
    • On beat 3, play three 16th-note triplets tied to an eighth note.
    • On beat 4, play a quarter note tied to beat 1 of the next bar.
    • This creates a flowing, continuous phrasing that challenges traditional barline perception.
  • 
  • Exercise:
    1. Practice the triplet grouping on beat 3 separately to internalize its feel.
    2. Connect the final quarter note into the next bar, ensuring seamless phrasing.
    3. Improvise over a steady pulse while incorporating this rhythmic idea.

  These advanced exercises develop a deep sense of polymetric awareness, allowing musicians to improvise freely while maintaining rhythmic displacement.

   

Final Thoughts

Longo’s rhythmic concepts transcend simple counting or metronomic precision. Instead, they activate a new behavior in rhythm, allowing jazz musicians to feel time at a deeper level. By internalizing these rhythmic shifts, musicians develop a natural swing and an instinctive sense of groove that goes beyond technical execution.
