Defining Pulse and Beat

The pulse is a steady, repeating timing level we can feel or tap in a piece of music. Pulse is neutral and constant — it does not yet tell us how the music is grouped or accented.

When we listen, we often notice several possible timing levels: a faster one, a slower one, and sometimes something in between. These layers form a hierarchy of timing levels.

The beat is the pulse level (or organization of pulse into hierarchical levels) that becomes metrically important - the level we most naturally move or tap along with. It emerges when pulse is organized into a hierarchical pattern of strong and weak positions, typically reinforced by accents, patterns, or the way the music is performed. In symmetric meters, the beat often directly corresponds to one pulse level; in asymmetric meters, the beat may group pulses of unequal duration (e.g., in 7/8, one beat might span three eighth notes while others span two).

In conducted music, the conductor shows the beat level to the ensemble. The conducting pattern tells performers which pulse layer should function as the beat.

Listening for Beat Level

Identify the beat level by determining the primary hierarchical layer of temporal organization.

Example 1: The Beatles, "Back in the USSR"

Example 2: The Duke Ellington Orchestra, "Ko-Ko"

Metrical Hierarchy

Once we feel the beat, we can often sense other steady layers. These may feel like smaller or larger durations, but they are all connected to the same pulse.

The metrical hierarchy comprises multiple timing levels, including the beat, divisions of the beat, and larger cycles (measures).

A metrical hierarchy consists of several timing levels: the beat, smaller durations within it, and larger durations formed by several beats.

The beat level can be broken down into smaller durations called the division level.

Try It: Detecting Multiple Levels

Listen: Joni Mitchell, "Help Me"

Identify the beat, then observe how smaller divisions articulate within it and how longer spans combine multiple beats into broader metrical cycles.

Simple Meter

Now that we understand the beat and its smaller durations (division level), we can describe how the music groups these beats into a repeating pattern. This pattern is the meter.

When the division level occurs in groups of 2, we call that a simple meter.

Important: A simple meter can have any number of beats. The term "simple" describes that the beat level divides into two division level parts.

Compound Meter

Not all beat levels divide into groups of two.

When the division level occurs in groups of 3, we call that a compound meter.

Important: A compound meter can have any number of beats. The term "compound" describes that the beat level divides into three division level parts.

Try It: Hearing Compound Meter

Listen: Horace Silver Quintet, "Señor Blues"

Tap the beat level, then determine the division level. Is it in groups of 2 or 3?

Pattern of Accents

In Week 1, we grouped pulses. Now, we listen for groupings at the beat level, because this is what defines the meter.

Along with the division level, we must also determine the grouping of beats in music in order to determine the meter.

Listen for the pattern of accented and unaccented beats.

Types of Accents

There are three types of accents: phenomenal, structural, and metrical.

A phenomenal accent can occur in many ways:

  • Written accent (>)
  • Extreme in register (very high or very low note)
  • Extreme in note length (very short or very long)
  • Change in instrumentation (added instrument)

Duple Meter

In much jazz and popular music, we hear a regularly occurring phenomenal accent every other beat.

This series of accents (accented-unaccented) illustrates that the meter is duple.

Listening Tip

In jazz and popular idioms, percussion patterns—specifically the placement of the snare and hi-hat—frequently delineate the metrical structure.

There is often a cymbal (hi-hat) or snare drum hit every other beat in a duple meter.

Example: Duple Meter

Listen: Count Basie Orchestra, "That Warm Feeling"

Can you hear the snare/cymbal accenting every other beat?

Triple Meter

Some music accents the beat level every third beat.

We describe this meter as triple.

Triple Meter Pattern

Example: Triple Meter

Listen: Jazz at Lincoln Center Orchestra, "Basque Song"

Can you feel the pattern of 3?

Summary

Consequently, a meter signature represents the intersection of a division structure (simple or compound) and a metrical structure (duple or triple).

Meter Signatures

In Simple Meters

Simple meter signature diagram showing 2/4 and 3/4 with explanation

Top number: indicates the number of beats per measure.

Bottom number: describes the duration of note that is at the beat level

In Compound Meters

Compound meter signature diagram showing 6/8 and 6/4 with explanation

Top number: describes the number of division level attacks present in each measure

Bottom number: describes the duration of note at the division level

Quick Reference

Simple meter: Top number = how many beats | Bottom number = what note gets the beat

Compound meter: Top number = how many divisions | Bottom number = what note is one division

Meter signatures summarize both the division structure and the metrical structure we just explored.
