Diatonic Scales Vs. The Chromatic Scale - Breaking The Intervals Down

Diatonic Scales

Music scales can seem quite complicated, especially when you're just delving into the world of music theory as a newbie. I'd like to offer an easy breakdown for budding musicians who want to get a firm grasp on the possibilities with scales they can use for their performances and songwriting. 

Diatonic scales are musical scales that consist of seven distinct pitch classes (notes), including five whole steps (whole tones) and two half steps (semitones) in each octave. These scales form the basis of much of Western music, particularly in the classical, folk, and popular genres.

The arrangement of whole and half steps is what defines the specific type of diatonic scale. The most commonly known diatonic scales are the major scale and the natural minor scale, each with its own specific pattern of whole and half steps.

Major Scale: The pattern for the major scale is Whole-Whole-Half-Whole-Whole-Whole-Half (W-W-H-W-W-W-H). For example, the C major scale, which consists of the white keys on a piano starting from C, follows this pattern: C-D-E-F-G-A-B-C.

Minor Scale: The (natural) minor scale has a different pattern: Whole-Half-Whole-Whole-Half-Whole-Whole (W-H-W-W-H-W-W). An example is the A minor scale, which also consists of the white keys on a piano but starts from A: A-B-C-D-E-F-G-A.

Besides these, the term "diatonic scale" can also refer to modes derived from these scales. The modes are scales created by starting the major scale from a different note but using the same sequence of whole and half steps. The modes are:

Ionian: The same as the major scale (W-W-H-W-W-W-H).

Dorian: Starts on the second degree of the major scale (W-H-W-W-W-H-W).

Phrygian: Starts on the third degree of the major scale (H-W-W-W-H-W-W).

Lydian: Starts on the fourth degree of the major scale (W-W-W-H-W-W-H).

Mixolydian: Starts on the fifth degree of the major scale (W-W-H-W-W-H-W).

Aeolian: The same as the natural minor scale (W-H-W-W-H-W-W).

Locrian: Starts on the seventh degree of the major scale (H-W-W-H-W-W-W).

Each mode has its own unique feel and tonal center, despite being composed of the same set of pitches as the major scale it is derived from. The concept of diatonic scales is central to understanding and analyzing Western music, as these scales and their modes provide a foundational structure for melody and harmony.

The Chromatic Scale 

The chromatic scale is a musical scale with twelve pitches, each a semitone apart. In other words, it includes all the notes of the octave within a twelve-note scale.

This scale is non-diatonic, meaning it does not adhere to the specific whole and half step arrangements of the diatonic scales (like major and minor scales). Instead, it encompasses all the notes available in the Western music system, including all the sharps and flats.

In a chromatic scale, each note is a half step (or semitone) away from the next, both ascending and descending. On a piano, this would mean playing every key in sequence, including both the white and black keys, from any starting note to the same note in the next octave.

For example, starting on C, the ascending chromatic scale would be:

C, C♯/D♭, D, D♯/E♭, E, F, F♯/G♭, G, G♯/A♭, A, A♯/B♭, B, C (octave higher)

And descending from C, it would simply be the reverse, going down in semitones:

C, B, B♭/A♯, A, G♯/A♭, G, F♯/G♭, F, E, E♭/D♯, D, C♯/D♭, C (octave lower)

The chromatic scale is often used for things like:

Warm-ups: Musicians might play chromatic scales as part of their practice routine to improve their technique and finger dexterity.

Improvisation: It provides a comprehensive set of notes that can be used for improvising over various harmonic contexts.

Composition: Composers/songwriters might use the chromatic scale to create tension, transition between keys, or introduce chromaticism into their music for color and variety.

Understanding the Mood and Color

Major Scale (Ionian Mode): Conveys happiness, brightness, and stability. Use it to write uplifting or joyful sections of your music.

Natural Minor Scale (Aeolian Mode): Imparts a sense of sadness, melancholy, or introspection. Ideal for more somber or reflective parts.

Dorian Mode: Offers a slightly jazzy or soulful feel, less sad than natural minor but more complex than major. Works well for creating a groove or a slightly moody vibe.

Mixolydian Mode: Brings a bluesy or slightly unresolved quality, perfect for rock, blues, and folk music.

Lydian Mode: Provides a dreamy, ethereal, or even somewhat 'magical' sound, great for creating a sense of wonder or uplift.

Phrygian Mode: Delivers a dark, exotic, or even tense atmosphere, fitting for dramatic or mysterious sections.

Locrian Mode: Though less commonly used due to its diminished fifth, it can impart a feeling of unease or dissonance, useful for very specific, tension-filled moments.

Chromatic Scale: Adds tension, color, or a sense of movement. It can be used to create interesting melodies or harmonies that stand out or to transition between sections or keys in your song.

Scale Tips for Songwriting 

Start with a Melodic or Harmonic Hook: Use a scale to create a catchy melody or chord progression that serves as the central theme of your song. Experiment with modes for unique sounds.

Use Chromaticism for Flavor: Chromatic notes can add interest or tension to your melodies and harmonies. Consider using them as passing tones (notes that lead from one scale tone to another) or to modulate to a different key.

Modulation and Variety: Change the mood or intensity of your song by modulating (changing the key) using diatonic or chromatic approaches. This can keep the listener engaged.

Combine Scales and Modes: Don't be afraid to mix scales and modes within a song or even a section for more complex emotional effects. For example, switching between major and minor modes can dramatically alter the song's mood.

Experiment with Instrumentation: Different instruments can bring out different qualities of the scales. For example, a lydian melody might sound ethereal on a synthesizer but mysterious on a string section.

Lyrics and Scales: The mood of the scale can complement your lyrics. A happy, major key melody can enhance uplifting lyrics, while a minor key can deepen the impact of sorrowful or introspective lyrics.

Ultimately, the best way to understand and utilize these scales in your songwriting is through continuous practice and experimentation. Analyze songs you enjoy to see how they use these scales, and try incorporating similar techniques into your own music.

Remember, there are no strict rules in music, so feel free to explore and express your creativity in the way that best suits your artistic vision!
