The answer for stage 3 are:

The Helmholtz Resonance of the 2019 Æther is tuned to: 
E2

Why is it important that the Helmholtz Resonance is tuned?
So that the entire instrument and vessel are in harmony and that the center notes fundamental frequency sits an octave above the chamber's fundamental and when played, it activates the Helmholtz Resonance creating a stacking of octaves.

The 2019 Æther has shoulder tones that are:
Tuned above the triple octave of the center notes fundamental and typically tuned to the scale.

Why is it important to have the shoulder tones tuned?
So that any frequency that can be generated from the instrument and material is intentionally intune adding to an overall clean, non-tanky sound.

The 2019 Æther is 21.5" in diameter because:
21.5” shifted the internal interference from Bb4 to Bb4-50cents, also shifting the secondary impedance from F#5 to F#5-50cents, leading to an overall cleaner sounding instrument. This is also why there are no scales that offer A4 and Bb4.
