18. Listen & Sing: Learn Major And Perfect Intervals By Singing 

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.

Learning To Sing Intervals

Interval names are based on scale notes. 

If we can sing, hum or imagine the sound of a scale, we can teach ourselves the character and name of various intervals by ear. We can count how many scale notes there are from the lower note of the interval to the higher note.

The easiest scale to sing, at least in Western culture, is the major scale. If you can’t sing a major scale straight away, please have a look at 17. Listen And Sing: How To Sing The Major Scale before reading on.

Major scale intervals

In 16. Intervals 1: Major, Minor And Perfect Intervals we saw that intervals are always counted from the lower note to the higher note, regardless of the order in which they’re played. The lower note of the interval becomes the root note of a major scale. We count scale notes to find the higher note and name the interval.

Counting up from the root note, the major scale contains the major 2nd, major 3rd, perfect 4th, perfect 5th, major 6th, major 7th, and, of course, the octave.

  • Treat the root note of the scale as the lower note of an interval.
  • Now sing from the root note to the 2nd note. This is a major 2nd.
  • To sing a major 3rd, sing the first 3 scale notes in a row but sing the 2nd note quieter or shorter than the first and third notes (see below). After a few times, leave the second note out altogether.
  • Repeat this exercise from the root note to each of the other notes in the scale.

Tip: the most useful intervals to become really good at are the major 3rd, perfect 5th and the octave. They are the notes of a major triad, a sound which will feel familiar to the ear and provide a shortcut for larger intervals (more on triads in Part 2 of my course).

Try These…

Below are the intervals of C major. Most voices can find a comfortable way to sing a C in the lower part of their range. The note number/scale degree is indicated below the notes.

  • In the first line, sing along to the first bar, then sing the same notes again in the second bar while you hear the interval played together. Feel your voice hit the lower and higher notes of the interval at the start and end of the bar.
  • In the second line the in-between scale notes are left out. Again, keep singing the first bar while you hear the interval played together in the second bar.
  • Practice each interval long enough until you don’t need to listen to the example while you sing.

Major 2nd

Major 3rd

Perfect 4th

Perfect 5th

Major 6th

Major 7th

Octave (perfect 8th)

Once you build a little confidence, choose a slightly lower or higher note for your intervals.

The more you do exercises like these, the easier it will be to recognise the interval between two notes, whether you hear them as a melodic interval (consecutive notes) or as a harmonic interval (both notes sounding together).

How To Sing An Interval Above A Note

This is just like how we learnt the intervals starting on C

  • Choose a major or perfect interval by name, such as a perfect 4th.
  • Play a note towards the bottom of your range.
  • Sing that note, then sing a note that’s the chosen interval above it 
  • If you need to, you can quietly sing the in-between scale notes like in the first exercise.

How To Name An Interval You’re Hearing

You can use the same method to name an interval that you hear.

  • First, identify both notes of the interval by singing them. They are a little harder to pick when played together.
  • Sing the lower note, then sing the notes of the major scale until you hear your note match the higher note, counting notes as you sing (the starting note counts as the first note). 
  • 2 notes is a 2nd, 3 notes is a 3rd, etc. The 2nd, 3rd, 6th and 7th are major intervals, the 4th and 5th are perfect. (Technically the octave is also perfect, we just don’t need to say so. An octave is just called an octave.)

Try These…

Below are audio files of a few harmonic intervals. Remember to sing both notes of each interval before singing (or thinking) scale notes. To make it a little easier, the two notes are quickly played as a melodic interval before hearing the two notes together.

Name each interval using the steps outlined above:
