This is an amplified resonating box of extra strings, like on a viola d'amore, but that stands alone, so that you can tune it differently and put it closer or further away from other instrucments to see how it rings in accordance with them.
The strings could be tuned to keys going up the scale in thirds, alternating major and minor third intervals, and with doubled strings, so that 24 strings could be used, two for each key.
So the strings would be tuned to the 12 notes of the scale, two strings for each note, so you could tune one to a low note and the other to the octave up and then control the volume of each, and optimize so that the box is as resonant as possible. Hopefully all of the major and minor triads for each of the keys will be represented in there, if you go up the scale in major and minor thirds you would get for instance, cmaj7, emin7, gmaj7, bmin7 etc eventually covering all of the major and minor triads.
So if all the notes are resonating equally, it would be like a blank state that the effects of really subtle things could be written on.-- JesusHChrist, Oct 23 2016 Resonance frequency-retuned quartz tuning fork as a force sensor for noncontact atomic force microscopy http://scitation.ai...4/10.1063/1.4891882 [beanangel, Oct 24 2016] There are way more than 12 notes.-- pocmloc, Oct 23 2016 Actually, there are only 12 notes. but they put on false moustaches and so on to give the illusion that there are more than 12.-- not_morrison_rm, Oct 23 2016 the fan in the refrigerator tunes everything-- JesusHChrist, Oct 23 2016 If you say so <starts edging towards the Esc button>-- not_morrison_rm, Oct 23 2016 are there resonance tuned AFM tips yet?
