Surprise! Those nice fractions make up the major scale. Starting with C produces the C major scale — the “natural” notes. Using ♯ to mean “one semitone up” and ♭ to mean “one semitone down”, we can name all of these notes.

0 1.000 = 1:1 C (unison)
1 1.059 C♯ or D♭ (semitone; minor second)
2 1.122 ≈ 1.125 = 9:8 D (whole tone; major second)
3 1.189 D♯ or E♭ (minor third)
4 1.260 ≈ 1.250 = 5:4 E (major third)
5 1.335 ≈ 1.333 = 4:3 F (perfect fourth)
6 1.414 F♯ or G♭
7 1.498 ≈ 1.500 = 3:2 G (perfect fifth)
8 1.587 G♯ or A♭ (minor sixth)
9 1.682 ≈ 1.667 = 5:3 A (major sixth)
10 1.782 A♯ or B♭ (minor seventh)
11 1.888 ≈ 1.889 = 17:9 B (major seventh)
12 2 = 2:1 C (octave)
