Beat Placement Principles

Root-Based Approach (Beginner)

For any chord, start with:

Beat 2: Passing tone
Beat 3: 5th (or root)
Beat 4: Approach note to next chord

Approach Notes (Chromatic & Diatonic)

Leading into the next chord root:

Essential Patterns for ii-V-I

Pattern 1: Root-3rd-5th-Approach

Dm7:     D - F - A - Ab (chromatic approach to G)
G7:      G - B - D - C# (chromatic approach to C)
Cmaj7:   C - E - G - (next chord approach)

Pattern 2: Root-5th-3rd-Approach

Dm7:     D - A - F - F# (chromatic approach)
G7:      G - D - B - B (leading tone to C)
Cmaj7:   C - G - E - (continue)

Pattern 3: Descending

Dm7:     D - C - B - A
G7:      G - F - E - D#
Cmaj7:   C - B - A - G

Chord Movement Patterns

Movement by 4th (Most Common)

When chord moves up a 4th (e.g., Cm7 to F7):

Ascending: C - D - Eb - E (to F)
or:        C - D - E - E (to F)

Movement by 5th

When chord moves down a 5th:

Descending: G - F - E - Eb (to D)

Static Chord (One chord for 2+ bars)

Create melodic interest:

Bar 1: Root - 3rd - 5th - 6th
Bar 2: Root - 2nd - 3rd - approach

Practice Exercises

Exercise 1: Root Movement

Play only roots in quarter notes through a tune's changes.

Exercise 2: Root-5th Pattern

Alternate root and 5th for each chord.

Exercise 3: Scale-Based Walking

Use chord scales to create stepwise motion.

Exercise 4: Approach Notes

Focus on smooth voice leading into chord changes.

Common Mistakes to Avoid

  1. Playing too loud - bass should support, not dominate
  2. Inconsistent time - use metronome practice
  3. Ignoring the drummer - lock with hi-hat on 2 & 4
  4. Too many notes - keep it simple and groovy
  5. Random note choices - outline the harmony clearly

Song-Specific Application

For any song:

  1. Identify the chord progression
  2. Map out root movement
  3. Add 5ths and 3rds on strong beats
  4. Connect with chromatic/diatonic approach notes
  5. Practice at slow tempo (60-80 BPM)
  6. Gradually increase to performance tempo
