cybele desires little oulipo, cast further spellspells

the text/sound is created from combining nine letters.  [t, h, e, n, s, c, y, b, l]
frequencies were determined by their number place in the alphabet
times a factor of ten & modulated by a factor of 100.
for instance other possible spellspells:
net yet bent she sent best set these chests then seen bench test
so: each sentence spells out the possible sounds that can be
played when they appear in the sequence.
