A scale is a set of notes in order. The major scale is the foundation of almost everything in Western music.

What is a Scale?

A or is a set of arranged in a specific order. Scales define the palette of notes used in a piece of music — the notes that sound 'in tune' with each other. Every melody, , and signature is built on top of a scale. Learning scales gives you a map of the keyboard and a vocabulary for understanding music.

The Major Scale — W-W-H-W-W-W-H

The is the most important scale in Western music. It's built from a formula of s (W) and s (H): W-W-H-W-W-W-H. The C major scale uses only the white keys — play from C to C and you've played a major scale. Its bright, happy sound comes from exactly where the two half steps land in the pattern.

Tip If you remember where the two half steps land (between E-F and B-C), the major scale rebuilds itself in any key.

C major scale — C D E F G A B

The Minor Scale — Darker and Moodier

The uses a different formula — W-H-W-W-H-W-W — which shifts where the s land and completely changes the mood. The A minor scale uses exactly the same notes as C major, but starting and ending on instead of . That single shift in starting note is why the two scales sound so different even though they share every note.

Tip Minor feels darker largely because its half steps arrive earlier in the pattern.

A minor scale — A B C D E F G

The Pentatonic Scale — Five Notes That Always Work

The removes the two 'unstable' notes from the major scale, leaving five notes that sound good together no matter what order you play them in. The C major pentatonic is , , , , . It's the most common scale for improvisation — in blues, rock, pop, and folk music — because every note sits comfortably over most s.

Tip Pentatonic is a great first improvisation scale. On a piano, the black keys form a pentatonic scale — try playing only the black keys to hear it.

C major pentatonic — C D E G A

Scale Degrees — Describing Patterns in Any Key

Scale degrees give each note in a scale a number: , , , , , , . The first note (the root) is always . Describing scales as formulas of degrees — rather than specific note names — means the same pattern works in every . When someone says 'the of the scale' in G major, they mean D. In F major, they mean C. The number stays the same, the note changes with the key.
