Aural Skills — Intervals, Chords, Progressions and Rhythm

Aural skills appear in the aural and written examinations for VCE Music studies. Regular short practice builds them faster than anything else.

Learning objective: Recognise intervals, chord qualities, cadences, common progressions and rhythmic patterns by ear, and transcribe short melodic and rhythmic fragments.

By the end of this lesson you can:

• I can identify common intervals and major, minor, diminished and dominant 7th chords.
• I can recognise cadences and common progressions such as I–IV–V and the 12-bar blues.
• I can transcribe short rhythms and melodies.

Your ear is a muscle. Ten minutes a day of interval and chord drills builds aural strength the way daily exercise builds fitness.

Intervals and chords

INTERVALS (in semitones) with reference songs you can use:
• minor 2nd (1) — tense, close
• major 2nd (2) — first two notes of a major scale
• minor 3rd (3) — sad, minor colour
• major 3rd (4) — bright
• perfect 4th (5) — strong, open
• tritone (6) — unstable
• perfect 5th (7) — open, hollow
• octave (12) — same note, higher

CHORDS
• Major: root + major 3rd + perfect 5th — bright.
• Minor: root + minor 3rd + perfect 5th — darker.
• Diminished: root + minor 3rd + diminished 5th — tense.
• Dominant 7th: major chord + minor 7th — wants to resolve.

Cadences and progressions

CADENCES (phrase endings):
• PERFECT V–I — finished, strong.
• PLAGAL IV–I — softer "Amen" ending.
• IMPERFECT (ends on V) — unfinished, like a comma.
• INTERRUPTED V–vi — surprise.

COMMON PROGRESSIONS:
• I–IV–V–I — the foundation of much folk and rock.
• I–V–vi–IV — heard in countless pop songs.
• ii–V–I — the core of jazz harmony.
• 12-BAR BLUES: I I I I | IV IV I I | V IV I I.

RHYTHM: count subdivisions aloud ("1 e & a"), notice syncopation (accents off the beat) and compound metres (6/8 feels in two big beats of three).

Worked example (Medium)

A phrase ends on chord V and feels unfinished. Which cadence is it, and how would you describe its effect?

1. Identify. Ending on V without resolving → imperfect cadence.
2. Effect. Creates expectation that the music will continue.

Answer: An imperfect cadence, creating suspense and the expectation of an answering phrase.

Common mistakes

• Guessing chord quality from mood alone Context can make major chords sound sad. Fix: Listen for the third: major 3rd = major, minor 3rd = minor.
• Writing rhythms without checking the bar total Beats per bar must match the time signature. Fix: Count every bar after transcribing.

Practice questions

1. Which cadence is V–I?

   1. Plagal
   2. Perfect
   3. Imperfect
   4. Interrupted

Summary

• Learn intervals by semitone count and sound.
• Recognise major, minor, diminished and dominant 7th chords.
• Know perfect, plagal, imperfect and interrupted cadences.
• Practise daily; transcribe rhythm before pitch.
