O = one, T = two, T = three, F = four (or five), S = six, S = seven, E = eight, N = nine, T = ten.
E
T-ty E .
"t-h-e s-o-u-n-d o-f s-t-a-t-i-c"
T is next because the letters o, t, t, f, f, s, s, e, and n all stand for the beginning letters in the numbers one, two, three, four, five, six, seven, eight, and nine. To explain further: o=one, t=two, t=three, f=four, f=five, s=six, s=seven, e=eight, and n=nine. Therefore, T would be next because ten is after nine numerically.
