27 Nonharmonic Tones

John Peterson

Key Takeaways

Overview

One of the tools that composers use to make music more interesting is the nonharmonic tone. Nonharmonic tones are pitches that are added to a composition that are not part of the surrounding chord. The nonharmonic tone creates dissonance which in turn creates momentary musical tension – a really cool effect. In this chapter you will learn about the various different kinds of nonharmonic tones and how they work, and learn how to identify them within a musical context.

How to Spot a Nonharmonic Tone

One of the most important skills to develop when working with nonharmonic tones is learning how to identify them. Once you have located a nonharmonic tone, it becomes much easier to determine its type, as the possibilities are fairly limited. The tutorial embedded below, Desperately Seeking Nonharmonic Tones, gives you an opportunity to practice finding nonharmonic tones in a musical selection with simple harmony.

Types of Nonharmonic Tones

In this next section we will explore the various types of nonharmonic tones, sometimes called “embellishing tones” or “non-chord tones”. These terms all mean the same thing.

Passing tones, neighbor tones: Nonharmonic tones that move by step

Example 1 showed the two kinds of embellishing tones that move by step: passing tones (PTs) and neighbor tones (NTs). Passing tones are approached by step and left by step in the same direction, either ascending or descending (Example 1). Neighbor tones are approached by step and left by step in the opposite direction, producing either an upper neighbor or a lower neighbor (Example 2).

Neighbor Tones by openmusictheory

Example 2. (a) Upper neighbor and (b) lower neighbor tones in a two-voice texture.

Double Neighbor Tones or Changing Tones

Double neighbor tones (DNT) (sometimes called “neighbor group” or changing tones (CT)) are made of two nonharmonic tones in a row. The first moves by step away from a chord tone, then skips to another nonharmonic tone, then moves by step to another chord tone, frequently the same chord tone.

Appoggiaturas and escape tones: Nonharmonic tones that involve a skip or leap

Appoggiaturas (APPs) and escape tones (ETs) involve either a skip or a leap. Appoggiaturas are approached by skip or leap and left by step in the opposite direction (Example 3). The appoggiatura typically occurs on a stronger part of the beat than its surrounding notes. Escape tones are approached by step and left by skip or leap in the opposite direction (Example 4). The escape tone typically occurs on a weaker part of the beat than its surrounding notes. It is more common for appoggiaturas and escape tones to be left by motion downward (Examples 3a and 4a) than upward (3b and 4b).

Examples 5 and 6 show the two kinds of embellishing tones that involve a leap: appoggiaturas and escape tones.

Suspensions, retardations, anticipations, and pedal tones: Nonharmonic tones involving static notes

There are four kinds of embellishing tones that involve static notes (i.e., notes that don’t move): suspensions (SUS), retardations (RET), pedal tones (PED) and anticipations (ANT)

Suspensions and Retardations

Suspensions are approached by a static note and left by step down, while retardations are approached by a static note and left by step up. They follow a similar pattern:

Preparation–>Suspension (or retardation)–>Resolution

Suspensions are indicated in Roman numeral analysis not only by their abbreviations, but by the simplified intervals of the suspension and the resolution above the bass note. Retardations do not need to be labeled with the intervals above the bass note.​

  • 9-8. 7-6 and 4-3 suspensions are above the bass voice.
  • 2-3 suspensions are in the bass voice.
  • Both suspensions and retardations are always on a stronger part of the beat than the surrounding notes.

Why are all suspensions in the bass voice called 2-3 suspensions? 

There is a pattern to the numbers used when the suspension is in an upper voice – the second number is always one less than the first number – 9-8, 7-6, 4-3. This is because the intervallic relationship between the upper notes and the bass voice gets smaller as the suspension resolves down by step (and closer to the bass). However, when the suspension is in the bass, the suspended note must still move down, making the resolution note farther away from all of the upper voices. This means the suspended note is closer to the upper notes, and the resolution is farther away, meaning that the intervallic relationship gets bigger. We use the numbers 2-3 because there will always be a 2-3 relationship between the suspension and resolution in the bass and one of the upper voices.

The fourth suspension in Example 7 demonstrates a 2-3 suspension. In this case the 2-3 relationship is between the bass and the “A” in the soprano voice.

Example 7 below illustrates how the melodic pattern of Preparation–>Suspension–>Resolution works, and the intervallic relationships of the various suspensions and resolutions to the bass voice.

Example 8 provides a few examples of retardations.

Pedal Tones

Pedal tones are often found in the bass. They consist of a series of static notes below chord changes that do not include the bass. We typically label them using the scale degree number of the pedal note, as in Example 9.

Example 9: Josephine Lang, Dem Konigs-Sohn, mm. 16-18 by openmusictheory

Anticipations

Like the suspension, retardation, and pedal tone, anticipations also involve static notes. But anticipations are a two-note (rather than three-note) gesture, in which a chord tone is heard early as a non-chord tone (Example 10). In other words, it “anticipates” its upcoming membership in a chord.

Summary

The table in Example 11 provides a summary of the embellishing tones covered in this chapter.

Embellishing Tone Approached by Left by Direction Additional Detail Example
Passing Tone (PT) Step Step Same May ascend or descend         Passing tone - a pattern of F-G-A in treble clef, the G is the passing tone
Neighbor Tone (NT) Step Step Opposite Both upper and lower exist Neighbor tones - a pattern of f-g-f in treble clef, the g is the neighbor tone.
Double Neighbor or Changing Tone (CT) Step then Skip Step Varies Chord tone to nonchord tone, to nonchord tone to chord tone Double neighbor tones or changing tones - in treble clef, a g, followed by an f, followed by an "a", followed by a g. The f and the "a" are the double neighbor tones.
Appoggiatura (APP) Leap Step Opposite Appoggiatura is usually on a strong part of the beat appoggiatura - a treble clef d followed by leap up to a g, resolving down to an F. The g is the appoggiatura.
Escape Tone (ET) Step Leap Opposite Escape tone is usually on a weaker part of the beat escape tone - in treble clef - an "a", followed by a g, which is the appoggiatura, followed by a leap up to a C.
Suspension (SUS) Static note Step Down Suspension is always on a stronger part of the beat suspension - a chord tone G, followed by the suspended G, resolving down to F, in treble clef
Retardation (RET) Static note Step Up Retardation is always on a stronger part of the beat retardation - in treble clef, e-e-f. The second e is circled, and this is the retardation
Pedal Tone (PED) Static note Static note N/A Stays on the same pitch Pedal tones - in bass clef, three g's in a row. The middle is circled, indicating that it is not part of whatever chord is being implied.
Anticipation (ANT) N/A Static note N/A The anticipation is usually on a weaker part of the beat anticipation - a chord tone e, followed by a non-chord tone f, which becomes the chord tone f. The first f is the anticipation.
