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


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
