Handout 4: Compound Time Signatures

What You’ll Learn:

• The difference between simple time (beats divide into 2) and compound time (beats divide into 3)
• How to count, feel, and play in 6/8, 9/8, and 12/8
• Why a dotted quarter note becomes “one beat” in compound time

Building On: Beginner Handout 04 (Rhythm & Time) — you learned about time signatures (4/4, 3/4, 2/4), note values, and how beats are organized. Those were all simple time signatures. Now we explore compound time, where beats have a completely different internal feel.

Simple vs. Compound: The Core Difference

In the beginner course, every beat naturally divided into two equal parts. A quarter note splits into two eighth notes. Tap your foot on the beat, and the subdivision is “1-and, 2-and, 3-and, 4-and.” This is simple time.

In compound time, each beat naturally divides into three equal parts. The subdivision is “1-and-a, 2-and-a.” This creates a “lilting” or “rocking” feel — like a waltz inside each beat, or the gentle sway of a boat.

Feature	Simple Time	Compound Time
Beat subdivides into	2 equal parts	3 equal parts
Basic beat unit	Quarter note	Dotted quarter note
Feel	Straight, march-like	Lilting, rocking, flowing
Counting	”1-and, 2-and"	"1-and-a, 2-and-a”
Common signatures	2/4, 3/4, 4/4	6/8, 9/8, 12/8

Why 6/8 Is NOT the Same as 3/4

This is the single most important concept in this handout. Both 6/8 and 3/4 have six eighth notes per bar, but they GROUP those notes differently:

3/4 = THREE groups of TWO (simple time, 3 beats)

• Count: 1-2, 3-4, 5-6
• Emphasis: ONE-two, THREE-four, FIVE-six
• Feel: waltz (oom-pah-pah)

6/8 = TWO groups of THREE (compound time, 2 beats)

• Count: 1-2-3, 4-5-6
• Emphasis: ONE-and-a, TWO-and-a
• Feel: jig, lullaby, rocking

Try this on your CT-X9000IN. Play six C notes as eighth notes. First, accent notes 1, 3, and 5 (3/4 feel). Then accent notes 1 and 4 (6/8 feel). Same notes, completely different character.

3/4 feel:  >  .  >  .  >  .     (three strong beats)
           C  C  C  C  C  C

6/8 feel:  >  .  .  >  .  .     (two strong beats)
           C  C  C  C  C  C

The Three Compound Time Signatures

6/8 — Two Beats Per Bar

6/8 means 6 eighth notes per bar, grouped as 2 beats of 3 eighth notes each.

Each “beat” is a dotted quarter note (a quarter note + an eighth note = 3 eighth notes).

How to count: “1-and-a, 2-and-a” or “1-2-3, 4-5-6”

Conducting pattern: Down-up (like 2/4, because there are 2 main beats)

Musical character: Lilting, swaying, dancing. Think of “Row, Row, Row Your Boat” or “Greensleeves” — both in 6/8.

9/8 — Three Beats Per Bar

9/8 means 9 eighth notes per bar, grouped as 3 beats of 3 eighth notes each.

How to count: “1-and-a, 2-and-a, 3-and-a” or “1-2-3, 4-5-6, 7-8-9”

Conducting pattern: Down-right-up (like 3/4, because there are 3 main beats)

Musical character: Expansive, flowing. Less common than 6/8 or 12/8, but creates a wonderful sense of space. Tchaikovsky’s waltz-like themes sometimes use 9/8.

12/8 — Four Beats Per Bar

12/8 means 12 eighth notes per bar, grouped as 4 beats of 3 eighth notes each.

How to count: “1-and-a, 2-and-a, 3-and-a, 4-and-a”

Conducting pattern: Down-left-right-up (like 4/4, because there are 4 main beats)

Musical character: Slow blues, soul ballads, “triplet feel” rock. Many blues ballads and slow rock songs are in 12/8. When someone says a song has a “triplet feel” or “shuffle,” they often mean 12/8.

Summary Table

Signature	Eighth Notes Per Bar	Main Beats	Feel
6/8	6	2 (dotted quarter)	Lilting, dance-like
9/8	9	3 (dotted quarter)	Expansive, flowing
12/8	12	4 (dotted quarter)	Blues ballad, slow shuffle

Reading Compound Time Notation

In compound time, the dotted quarter note equals one beat. This changes how you read note values:

Note	Value in 4/4 (Simple)	Value in 6/8 (Compound)
Eighth note	Half a beat	One-third of a beat
Quarter note	One beat	Two-thirds of a beat
Dotted quarter note	One and a half beats	ONE BEAT
Dotted half note	Three beats	TWO BEATS (one full bar of 6/8)

The key insight: in compound time, the “natural” beat is dotted. If you see 6/8 and tap your foot on each main beat, you are tapping dotted quarter notes.

How to Count and Feel Compound Time

Step 1: Clap the Subdivision

Set your CT-X9000IN metronome to a comfortable tempo. For 6/8, clap six even eighth notes per bar:

Clap: x x x x x x | x x x x x x |

Count: 1 2 3 4 5 6 | 1 2 3 4 5 6 |

Step 2: Add Accents

Now accent beats 1 and 4:

Clap: X x x X x x | X x x X x x |

Count: 1 2 3 4 5 6 | 1 2 3 4 5 6 |

> > | > > |

Feel the “rock” between the two accented beats. That rocking feel IS 6/8.

Step 3: Tap the Main Beats

Now just tap the two main beats (1 and 4) and feel the three subdivisions between them:

Tap: X . . X . . | X . . X . . |

Count: 1-and-a 2-and-a | 1-and-a 2-and-a |

Step 4: Play on the Keyboard

Play a simple melody in 6/8 on your CT-X9000IN. Use the lower notes for beats 1 and 4, and upper notes for the subdivisions:

  RH plays:  C  E  G  C  E  G  |  C  E  G  C  E  G  |
  Counting:  1  2  3  4  5  6  |  1  2  3  4  5  6  |

This is a broken chord pattern (arpeggio) in 6/8 — one of the most natural ways to play in compound time.

Compound Time in Music You Know

”Greensleeves” (6/8)

This famous melody is one of the best examples of 6/8 feel. The melody lilts between two main beats per bar, with the “and-a” subdivisions creating the characteristic Renaissance dance feel.

Blues Ballads (12/8)

Slow blues songs like “Stormy Monday” or “The Thrill Is Gone” use 12/8. Each beat has a triplet subdivision that gives the music its characteristic “swing” at a slow tempo. On your CT-X9000IN, try selecting a slow blues rhythm pattern — it will be in 12/8 or have a triplet feel.

Barcarolles (6/8)

A barcarolle is a type of piece inspired by Venetian gondolier songs. The 6/8 time mimics the rocking of a boat on water. Offenbach’s famous “Barcarolle” from The Tales of Hoffmann is a perfect example.

Some Bollywood Songs

Several Bollywood songs use compound time. “Tere Bina” (from Guru) has a lilting 6/8-like feel. The compound subdivisions give these songs a flowing, emotional quality that differs from the straight-beat feel of most pop music.

Bridge to Indian Music: The Taal System

Indian classical music organizes rhythm through the taal (also spelled “tala”) system. A taal is a repeating rhythmic cycle made up of beats (matras) grouped into sections (vibhags).

Two common taals have strong parallels to compound time:

Dadra Taal (6 Beats)

Dadra has 6 matras (beats) grouped as 3 + 3:

Dha  Dhi  Na  |  Dha  Tu   Na
1    2    3   |  4    5    6
[--- vibhag 1 ---|--- vibhag 2 ---]

This grouping parallels 6/8 in Western music (two groups of three). The feel is lilting and used for light classical (thumri, dadra) and many Bollywood songs.

Keherwa Taal (8 Beats)

Keherwa has 8 matras grouped as 4 + 4:

Dha  Ge  Na  Ti  |  Na  Ka  Dhi  Na
1    2   3   4   |  5   6   7    8
[--- vibhag 1 ---|--- vibhag 2 ------]

While Keherwa is technically 8 beats (not compound time), its internal feel often has a lilting, uneven quality (emphasising beats 1 and 5) that is rhythmically akin to compound time’s “grouped in threes” feel when played at certain tempos.

The key parallel: both Western compound time and Indian taal organize rhythm into hierarchical groups where some beats are stronger than others, creating a “shape” that musicians feel in their bodies.

Try on your CT-X9000IN: Select one of the Indian rhythm patterns (the CT-X9000IN has 39 Indian rhythms). Listen for the grouping of beats — you will hear the taal structure creating a feel very similar to how compound time signatures create feel in Western music.

Exercises

1. Clap and count in 6/8. Set your metronome to 60 BPM for the dotted quarter note (each click = one main beat). Clap the subdivisions: “1-and-a, 2-and-a.” Do this for 2 minutes until the triple feel becomes natural.

2. Clap and count in 12/8. Same metronome setting, but now count four main beats: “1-and-a, 2-and-a, 3-and-a, 4-and-a.” This is the slow blues feel.

3. Play a 6/8 arpeggio pattern. In C major, play C-E-G (LH) then C-E-G (RH) as six eighth notes in 6/8. Accent the first note of each group. Then try the same in A minor: A-C-E, A-C-E.

4. 3/4 vs 6/8 comparison. Play six notes (C-C-C-C-C-C) accenting 1-3-5 (3/4), then play the same notes accenting 1-4 (6/8). Feel the difference in your body. 3/4 is a waltz; 6/8 is a lullaby.

5. Simple melody in 6/8. Play “Greensleeves” or any melody in 6/8 from your sheet music collection. Focus on feeling TWO main beats per bar, not six individual beats. Let the subdivisions flow naturally.

Quick Quiz

1. What is the main difference between simple and compound time? — Answer: In simple time, beats divide into 2 equal parts; in compound time, beats divide into 3 equal parts

2. How many main beats does 6/8 have per bar? — Answer: 2 main beats (each is a dotted quarter note)

3. Why is 6/8 different from 3/4 even though both have six eighth notes per bar? — Answer: 3/4 groups them as 3 groups of 2 (three beats); 6/8 groups them as 2 groups of 3 (two beats). The accents fall in different places

4. What note value equals one beat in compound time? — Answer: The dotted quarter note

5. What is the name for the Indian rhythmic cycle system that parallels Western time signatures? — Answer: Taal (tala) — a repeating cycle of beats organized into groups

Key Takeaway

Compound time is not a different counting system — it is a different FEEL. Where simple time marches (1-and, 2-and), compound time dances (1-and-a, 2-and-a). Once you feel the triple subdivision in your body, 6/8, 9/8, and 12/8 become as natural as 4/4.
