Scale Degrees are Named Numerically in Ascending Pitch Order

Modes are named in ascending pitch order

Each note in a scale represents a scale degree and they are named numerically in ascending pitch order using roman numerals. The number of degrees in a scale is equal to the number of notes in that scale. For example, the scale above has five notes, and thus has five scale degrees. A 7-tone scale will have seven scale degrees and so on.
