Non-Diatonic Piano Scale Patterns

Here you will learn about interesting and useful piano scale patterns that are not major or minor, and how to easily find them on the piano keyboard. No note reading required!

5 Non Diatonic Piano Scale Patterns

Five common non-diatonic music scales can be bound easily on a piano keyboard. Spice up your playing by checking out and learning these easy picture scales!

1. The Pentatonic Scale

The pentatonic scale-pattern has no ½ steps and consists of five notes. This scale is easy to use for composing and improvisation since it can easily be found on the black keys:

It doesn't matter where you begin actually. Any of the black keys can be used as the "root" or tonal "center".  Sometimes you will hear that a pentatonic scale is in "major" or "minor". This depends on the color it gets from where the largest interval (1 1/2 steps) is positioned.

For example, starting on C# as above, the largest interval is between the 2nd and 3rd key. This is called "Major" pentatonic. If you start the scale on Bb, the largest interval will be between this 1st key and the second. This is called a "minor" pentatonic. This is the basic pattern of the Blues scale as well, as you will see below.

Even though the pentatonic scale pattern is easiest to see on the black keys, doesn't mean it has to be played there! Every scale can be moved (transposed) to any key on the piano, you just have to keep the same pattern of steps.

2. The Chromatic Scale

The name is from Greek [Chroma] which means "color". This refers to the chromatic changes of a note- a 1/2 step up or down etc, which was/is often used for embellishments or decoration of a melody- that's what the word "color" stands for!

The scale consists only of ½ steps, and gives you no sense of tonality, because the notes are exactly evenly apart, so it doesn't really matter from what note you start or end the chromatic scale.

3. The Whole Tone Scale

You guessed it- it consists of only whole tones/steps! It was used by Debussy for ex. in “La Mer” for a beautiful flowing sound in the style of "Impressionism". Again- since the notes are constantly a whole step or tone apart there is no sense of center or tonality, which gives it a freer more open sound than major and minor.

4. The Blues Scale

Even though it is basically a minor pentatonic scale, the blues scale pattern consists of 6 different pitches, and uses both ½, whole and 1 ½ steps. It is a modification of the original blues scale to at least try to imitate the "blue" notes, or "bent" pitches of the blues but still be able to play it on for example the piano.

5. The 12 Tone Series

This scale pattern was introduced by the Austrian composer Arnold Schoenberg in the early 20th century as a way to break away from the traditional sounds of major, minor and modal patterns.

A way to explore the borders of tonality- and a-tonality; by avoiding any association with tonality at all!

Twelve tone music is also called serialism, since it is made up of an organized row, or series, of the 12 chromatic tones. This series has then to be repeated in specific ways. All association with major and minor is in this way avoided, for a more "dissonant" sound color.

This type of "scale"is not common at all, but fun to know about!

12 tone series

Play the numbers in any order you like. But a number can not be repeated until all 12 have been played! This is your 12 tone series. Now play it backwards, that is called retrograde. (There is a whole philosophy behind this, what I showed you is just a teeny, weeny little beginner bit!)

Remember- Any piano scale pattern can start from whatever note you want! You just need to make sure to follow the exact pattern of whole and half steps, or more, for that particular mode- and there it is in a new key- transposed!
