4 Ways to View A Scale’s Intervalic Formula using Tessitura Pro App for iOS and macOS

There are 4 ways you can represent a scale’s intervalic formula:

• Degrees
• Chord-Tones and Tensions
• Roman Numerals
• Melodic Intervals

Degrees

Here’s the major scale (Ionian) as degrees.
1 2 3 4 5 6 7 (all degrees al major)

Chord-Tones and Tensions

The major scale as chord tones (1 3 5 7) and tensions (9 11 13)

Roman Numerals

Viewing a scale over the circle of fifths you can see the Roman numerals for each degree in the scale. The Ionian (or major scale) is then IV I V II VI II VII

Melodic Intervals

The melodic intervalic formula for the major scale is: W W H W W W H
