scale steps repeat in both directions
f = base frequency
(f * 2) and (f/2) sound so much like f that it is necessary to number the steps between f and f*2 only
| step | frequency | |
|---|---|---|
| 7 | 1500 | octave 3 |
| 6 | 1333 | |
| 5 | 1200 | |
| 4 | 1066 | |
| 3 | 1000 | |
| 2 | 900 | |
| 1 | 800 | |
| 7 | 750 | octave 2 |
| 6 | 666 | |
| 5 | 600 | |
| 4 | 533 | |
| 3 | 500 | |
| 2 | 450 | |
| 1 | 400 | |
| 7 | 375 | octave 1 |
| 6 | 333 | |
| 5 | 300 | |
| 4 | 266 | |
| 3 | 250 | |
| 2 | 225 | |
| 1 | 200 |
octave = 7 scale steps
f sounds so much like f * 2 because it is mathematically so similar (put image of two sine waves here - f and f * 2)
