At least the new avoids the homophonic inconvenience.
"Society for Pure English Tract 4" by John Sargeaunt
Folk melodies are, without exception, homophonous.
"Critical & Historical Essays" by Edward MacDowell
For an exhaustive explanation of phrase-extension, with all the technical details, the student is referred to my HOMOPHONIC FORMS, Chapter III.
"Lessons in Music Form" by Percy Goetschius
Homophonous: words differently written but indistinguishable in sound, applied to different conceptions.
"Explanation of Terms Used in Entomology" by John. B. Smith
The essential difference between homophonic and polyphonic style is implied by the terms themselves.
"Music: An Art and a Language" by Walter Raymond Spalding
Opposed to it is homophonic, or single-voiced, music, in which one melody or part is supported by an accompaniment.

In science:

The possibility of achieving greater secrecy by introducing additional randomness into the plaintext of a cipher before encryption was known, according to , already to Gauss, in the form of the so-called ‘homophonic substitution’.
Quantum Noise Randomized Ciphers
Because of the additional randomness in the ciphertext, it typically happens that the ciphertext alphabet Y needs to be larger than the plaintext alphabet X (or else, Y is a longer sequence than X, as in homophonic substitution).
Quantum Noise Randomized Ciphers
For the case of STA on the key when the plaintext Xn has nonuniform but i.i.d. statistics, the so-called homophonic substitution method provides complete information-theoretic security, i.e. H (K |Yn) = H (K ) .
Quantum Noise Randomized Ciphers
The original form of homophonic substitution involves assigning to each plaintext symbol a number of possible sequences of length l proportional to its a priori probability in such a way that all possible l-sequences are covered.
Quantum Noise Randomized Ciphers
To put it another way, a statistical attack has been converted to a ciphertext-only attack. A generalized homophonic substitution that allows each symbol to be coded into sequences of variable length is discussed in , for which it is shown that sometimes data compression instead of data expansion results.
