The scale that hides inside your chords

You already play open chords / no theory needed / C major scale

You already play chords. A scale is the note palette those chords are made from, and the source of every melody you will ever sing or play. In this lesson you will learn the C major scale, the friendliest scale there is, and discover that it is already living inside the C, F, and G chords you play every day.

1. What is a scale?

A scale is a set of notes that sound good together, ordered from low to high. When you hum a melody you are picking scale notes one at a time; when you strum a chord you are playing several scale notes at once.

The C major scale is the best place to start because it is the only major scale built from natural notes: no sharps or flats at all. The major scale is also the cornerstone of western harmony, so it pays to meet it early.

2. The notes

Say them out loud, low to high:

C D E F G A B

Seven notes, then C repeats an octave higher. You already own most of these notes as pieces of your open chords: C, F, G, Am, Dm, and Em all live here.

3. Play the C major scale

This is the scale in open position, near the nut, using open strings. Red circles are the C notes, also called the root. Dark circles are the rest of the scale. Numbers below the strings are frets; a 0 means play the open string.

  1. Find the starting C at the 3rd fret of the A string. It is the red note at the bottom left.
  2. Play slowly upward, saying each note name as you go: C D E F G A B C.
  3. Come back down the same path to the low C.
  4. Repeat until it feels smooth, about two minutes. That is the whole scale.
Fingering

Let your fingers roughly match the frets: your 3rd finger takes fret 3, your 2nd takes fret 2, and so on. Start slow with all down-picks, then try alternating down up down up once you are steady.

Sing it

Say, or better, sing each note as you play it. Matching your voice to the guitar trains your ear, and your ear is the instrument that writes songs.

4. The click: your chords are already in the scale

A chord is made by taking notes from the scale and playing them together. Look what happens with the chords you already know:

  • C chord = C + E + G
  • F chord = F + A + C
  • G chord = G + B + D

Every note of all three chords is inside the scale. Now watch the C chord appear inside the scale. The amber notes are the C, E, and G that your C chord is made of:

That is why the C-F-G progression works: every chord draws from the same palette, so any scale note can sound right over those chords. C, F, and G are the I, IV, and V of the key of C, one of the most-used chord families in pop songwriting.

5. Try it now

Practice: 6 minutes
  1. Play the scale up and down twice, slowly, saying the notes.
  2. Strum a C chord, let it ring, then play just the amber notes C-E-G up the scale. That is your first mini-solo.
  3. Over a C-F-G strum, pick any four scale notes and make up a little melody. There are no wrong answers here; every note belongs. Keep that melody. The next lesson can build on it.

Check what stuck
