The 19 steps of the bearing plan in detail:
1 | c1-c0 | Descending octave from middle c |
2 | c1-f0 | Descending pure fifth from middle c. Verify pure fourth c0-f0 |
3 | f0-Bb | Descending pure fifth |
4 | Bb-bb0 | Transposition by ascending octave. Verify pure fourth f0-bb0 |
5 | bb0-eb0 | Descending pure fifth. Verify pure fourth Bb-eb0 |
6 | eb0-eb1 | Transposition by ascending octave. Verify pure fourth bb0-eb1 |
7 | eb1-ab0 | Descending pure fifth. Verify pure fourth eb0-ab0 |
8 | g#0-c#0 | Descending pure fifth |
9 | c#0-c#1 | Transposition by ascending octave. Verify pure fourth g#0-c#1 |
10 | c#1-f#0 | Descending pure fifth, Verify pure fourth c#0-f#0 |
11 | f#0-B | Well-tempered fifth. Within the B-major triad the third B-d#0 must beat six times faster than the fifth B-f#0 |
12 | B-b0 | Transposition by ascending octave |
13 | b0-e0 | Descending pure fifth. Check enlarged basic third c0-e0: must beat very slightly indeed from above. Verify pure fourth B-e0 |
14 | e0-e1 | Transposition by ascending octave |
15 | c0-g0 | Well-tempered fifth, flattened. Must beat from below at the same rate as the third c0-e0 beats from above within the C-major triad. Beats slightly faster - virtually at the same pace - as the well-tempered fifth B-f#0 a semitone below |
16 | g0-d1 | Well-tempered fifth. Flattened to beat 3/2-times faster than c0-g0 |
17 | d1-d0 | Transposition by descending octave |
18 | d0-a0 | Well-tempered fifth. Beats hardly faster - virtually at the same rate - as c0-g0, a whole tone below |
19 | a0-e1 | Check: This must be a well-tempered fifth; e1 must not be changed. Compare beat-rate with g0-d1 a whole tone below. Play c-e-g and listen to this well-tempered C-major triad which opens the door to performing music in all 24 keys, both major and minor. |
