What is the number assigned to each note of a scale?

In Music Theory, each note of a scale is assigned a number based on its position within the scale, typically referred to as scale degrees. For example, in a major scale, the first note is assigned the number 1 (tonic), the second note is 2 (supertonic), the third is 3 (mediant), and so on, up to the seventh note, which is 7 (leading tone). This numbering helps musicians understand relationships between notes, chords, and harmonies within the scale.
