Ok reason for this... these are all 1 octave apart.
hope this sheds some light for you
Ok, yes thanks. That's what I thought.
Just wondering why they didn't go on from their 33Hz start. That would have made it very simple visually: each vertical line would correspond to one of the C notes of the piano.
Since they started like this, I was wondering why they didn't keep going up.
