Scales and keys

A major scale follows a fixed pattern of tones and semitones, giving each key its own set of sharps or flats shown in the key signature. Minor scales use a different pattern and are usually described as darker. The tonic is the home note: music tends to sound resolved when it returns there.

Triads and chord numbering

A triad stacks the first, third and fifth notes of a scale. Building a triad on each degree gives the chords of the key, numbered with Roman numerals: in a major key, chords I, IV and V are major and ii, iii and vi are minor. Numbering rather than naming lets you transpose a progression into any key.

Cadences and expectation

A cadence is how a phrase closes. V to I sounds finished; IV to I sounds gentler; ending on V leaves the phrase open, which is why verses often hang before a chorus. Composers use expectation deliberately: an interrupted cadence substitutes an unexpected chord and surprises the listener.

Harmony across styles

Blues uses dominant-seventh chords on I, IV and V, giving its characteristic edge. Pop frequently loops I-V-vi-IV. Jazz extends chords with sevenths and ninths and substitutes freely. Modal folk avoids the strong pull of V to I, and much non-Western music organises pitch through mode and drone rather than functional harmony.

Common mix-ups

Things people often get wrong

  • People often think minor simply means sad. It is a different scale pattern, used expressively in many ways.
  • People often think a key signature only shows sharps or flats. It identifies the key and its home note.

How a song builds

Most popular songs are built from a small number of sections: an intro, a verse that tells the story, a pre-chorus that raises tension, a chorus that lands the main idea, and a bridge that changes direction before the last chorus.

Writers control energy with texture and range, not just volume. Stripping the drums out for four bars makes the next chorus feel twice as big. Lifting the vocal melody a few notes higher makes the chorus feel like the roof coming off.

Listen for what disappears, not only for what arrives. The quietest bar is often the one doing the most work.

Written for Good Learning Co.

Reading questions

  1. Listen to a song and write down its sections in order, with rough timings.
  2. Describe two moments where the texture changes and what effect each has.
  3. Plan your own 16-bar section, saying which instruments enter and where.

  • Listening notes

    Writing
