B16. Listen And Sing: Learn To Sing Major And Minor Triads

This post is one of a 2-part series of free basic music theory lessons on my blog, musictheoryde-mystified.com. You can see the complete list here. Please feel welcome to make a comment or ask a question.

How To Sing A Major Triad

To get started, sing a major scale with the chord notes long and strong and the notes in between quick and quiet.

The scale notes between the notes of the triad are called passing notes. Gradually weaken the passing notes until you’re just singing the chord notes as a triad in root position.

Inversions Of Major Triads

Now practise singing major triads in each inversion. As you sing, try to hear and feel the root note when you sing it. To help, you can accent the root note slightly as you sing.

The examples below include passing notes in the first bar, as a listening cue. Sing the second bar while you listen to the first bar.

Root position

1st inversion

2nd inversion

Once you’re familiar with these, try them in different keys (starting on different notes).

A Quick Way To Find the Root Note of a Major or Minor Triad

  • In 1st and 2nd inversion there is a perfect 4th between two of the notes. The root note is the higher of these two notes.
  • If there is no perfect 4th the triad is in root position (the root note is the lowest note of the triad).

Minor Triads

Now let’s learn minor triads. Here are three methods you can choose from:

  1. Sing a natural minor scale as above, emphasising the triad notes.
  1. The melodic minor ascending might be easier to sing than the natural minor. Since we’re only after the 1st, 3rd and 5th notes, it’s your choice: sing the minor you’re most familiar with.

For both methods, gradually weaken the passing notes until you’re just singing the triad.

  1. You can skip the minor scale altogether and go straight for the triad. The only difference between a major and a minor triad is the 3rd, which is flattened compared to the major 3rd (1 semitone lower than the major 3rd).

Whichever method you use, once you can sing the triad in root position, practice singing each inversion.

The examples below include the passing notes in the first bar, as a listening cue. Sing the second bar while you listen to the first bar.

Root position

For 1st and 2nd inversion I have included passing notes for both natural and melodic minor. Choose your preference.

Ist inversion

2nd inversion

Once you’re familiar with these, try them in different keys.

B15. Chord Voicing: Inversions Of Triads

This post is one of a 2-part series of free basic music theory lessons on my blog, musictheoryde-mystified.com. You can see the complete list here. Please feel welcome to make a comment or ask a question.

Voicing

The notes of a chord can be used more than once, at different octaves or in unison. They can also be played in any pitch order, not just as listed in the content.

The following are all a C major chord:

Arranging the notes of chords into a specific pitch order is called voicing.

There are many possible ways to voice a chord but the difference in character is often minimal. It’s not uncommon for chord parts to leave much of that detail up to the player, rather than write down the exact order of the notes. Chord charts are a good example of this approach.

However, there is one aspect of voicing that has an obvious impact on how the chord sounds, and that is the lowest note. It’s one detail that we should be able to describe, even in a chord chart.

Inversions Of Triads

The most significant note in how a chord is voiced is the lowest note. The lowest note in a chord is called the bass note, even if it’s not particularly low.

The bass note has more influence in the character of the chord than the higher notes. 

  • When the root note is lowest, we say the chord is in root position
  • When the 3rd is lowest, the chord is in 1st inversion 
  • When the 5th is lowest, the chord is in 2nd inversion

Note: More complex chords also have a 3rd inversion. We’ll look at 3rd inversion chords in B21. Dominant 7th Chords/inversions.

Inversions of Major Triads

The easiest way to change the inversion of a triad is to take the lowest note and put it up an octave.

Let’s look at a major triad, C major. 

You can spot which inversion a triad is in by looking at the intervals from note to note.

  • in root position we have a Major 3rd, then a minor 3rd
  • In 1st inversion we have a minor 3rd, then a perfect 4th
  • In 2nd inversion we have a perfect 4th then a major 3rd

Inversions of Minor Triads

Now let’s look at a minor triad, for example C minor.

The degrees are the same as the inversions of a major triad. Only the quality of the 3rds is different.

  • in root position we have a minor 3rd, then a Major 3rd
  • In 1st inversion we have a Major 3rd, then a perfect 4th
  • In 2nd inversion we have a perfect 4th then a minor 3rd

If the notes are written on a stave, you can spot the inversion for both major and minor triads by just counting scale notes (degrees).

Here are the same inversions as notes on a stave.

In the above examples the notes were written in their default pitch order, as consecutive notes in the triad. Often, the notes will be in a different order: the notes of a chord can be in any pitch order. Notes can be in different octaves, even multiple octaves. 

For inversions, we ignore all of that detail. The only thing that affects the inversion is the bass note. If the bass note is the same then the chord is in the same inversion.

The bass note determines the inversion, regardless of the order of the higher notes. 

The following C major chords are all in 1st inversion:

How To Name A Chord And Its Inversion 

You can work out the name and inversion of a triad by its content. That is, by removing any extra octaves and listing the notes in triad order. Once the content is listed in order, the inversion is easily seen by looking at the intervals from note to note.

Method:

  1. Name each note in the chord, excluding octaves
  2. Write the content in triad order, lowest note first
  3. Name the intervals between consecutive notes in the content
  4. Match the order of the intervals to a chord inversion; either root position, 1st inversion or 2nd inversion
  5. Name the root note, based on the pattern of intervals in the previous step
  6. Name the chord and it’s inversion

Example:

The notes in the example and exercises below are played slightly arpeggiated so you can hear the individual notes more clearly.

  1. From low to high, the notes are E C# A E A
  2. The content, from the lowest note up and in triad order, is E A C#
  3. E-A = perfect 4th, A-C# = Major 3rd
  4. perfect 4th + Major 3rd is the pattern of a major chord in 2nd inversion
  5. In 2nd inversion, the root note is the middle note (the upper note of the perfect 4th) = A
  6. A major 2nd inversion

The following chords are major or minor triads. There are no key signatures so you can’t assume they’re C major or A minor chords…

Name each chord and state its inversion (root position, 1st inversion or 2nd inversion).

TIP: Shortcut For Finding the Root Note of a Triad

  • If you see two chord notes that are a perfect 5th apart, the lower note is the root note.
  • If you see two chord notes a perfect 4th apart, the upper note is the root note.

Inversions and Chord Symbols: Slash Notation

For chord charts, there’s an easy, concise way to describe the inversion of a chord in a chord symbol, called slash notation.

In slash notation, we write the chord name, then a forward slash followed by the name of the bass note. 

For example, a C minor chord in 1st inversion has an Eb bass.
This would be written as Cm/Eb

In a chord chart, it’s like having a bass line as well as the chords rolled into one part.

Note: When the chord is in root position we don’t use a slash note, as the bass note is already in the chord name.

Try These… 2

Write the following chords in slash notation:

  • Work out the name of the bass note
  • Write the chord symbol, then a forward slash, then the name of the bass note
  1. A major chord in 1st inversion 
  2. E minor chord in 1st inversion 
  3. D major chord in 2nd inversion
  4. F minor chord in 2nd inversion
