In music theory, a scale is a set of musical notes ordered by pitch. They can be acsending (increasing in pitch) or descending (decreasing in pitch).

Most scales are octave repeating, this means that the pattern of notes are the same at any octave.

There are many different types of scales, each defined by the number of notes per octave.

Chromatic

12 notes per octave

Also know as dodecatonic.

Octatonic

8 notes per octave

Mostly used in jazz and modern classical music.

Heptatonic

7 notes per octave

The most common modern western scale.

Hexatonic

6 notes per octave

Common in western folk music.

Pentatonic

5 notes per octave

Common in folk music, especially in Asian music. Also known as the "black note" scale.

Tetratonic &

4 notes per octave

Tritonic &

3 notes per octave

Diatonic

2 notes per octave

Are all generally limited to prehestoric primative music.

Monotonic

1 notes per octave

Limited use in religious worship and for effect in modern art music.

Aswell as having different types of scales, we can have different modes of scales. Each mode is defined by the rotation of intervals. Intervals are split into two types, whole steps and half steps.

A whole step is an increase in two notes i.e. C to D or E to F#. These are noted as a "w".

A half step is an increase in one note i.e. C to C# or E to F. These are noted as a "h".

The interval pattern of a major scale is WWHWWWH. The major scale is also refered to as the Ionian mode. We can rotate this mode to create the Dorian mode WHWWWHW.

As you can see by rotating this scale by 1 place we've gone from

WWHWWWH

to

WHWWWHW

Here are the all the modes:
