Scales

Lesson 7 of 8 · ~7 min · Interactive

A scale is a ladder of notes climbing from a starting note to its octave. Almost every melody you know lives inside one. And here’s the secret most beginners never hear: a scale isn’t a set of notes - it’s a pattern of steps you can start anywhere.

1.What is a scale?

Play the white keys from C up to C and you get the C major scale - do, re, mi, fa, sol, la, ti, do. The starting note is called the tonic; it’s “home base,” the note where melodies feel finished.

2.The major pattern: W-W-H-W-W-W-H

Look closely at the steps between those notes. From C to D is a whole step (W). D to E: whole. E to F: half (H) - remember, no black key between them. The full climb is:

WWHWWWH

That sequence - whole, whole, half, whole, whole, whole, half - is the major scale. It’s what makes major sound like major.

3.Starting somewhere else

Start the same W-W-H-W-W-W-H pattern on G, and count carefully: you’ll need F♯ instead of F to keep the pattern intact. Start on D and you need two sharps. This is exactly why accidentals exist - and it leads straight to key signatures in the next lesson.

4.The minor scale

Change the step pattern to W-H-W-W-H-W-W and the ladder turns melancholy - the natural minor scale. Play the white keys from A to A and you’ll hear it: same seven notes as C major, but with A as home base, the mood transforms. Major and minor scales that share notes like this are called relatives.

5.Practice: build the scales

Build two scales key by key, in order. First C major (easy - all white), then G major - watch out for that F♯! Correct keys stay lit.
