The term word music includes all of the following devices except -a) rhythm and meter b) rhyme and repetition c) simile and metaphor d)...

The term word music refers to words, either by themselves or read together that make  sounds similar to those heard in music.

a) Rhythm and meter have the same meaning in words as they do in music: the variations of stressed and unstressed beats. here's an example of word rhythm/meter from Poe's "The Raven" showing stressed and unstressed syllables:

ONCE u PON a MID night DREAR y, WHILE i POND ered WEAK and WEARy

b) Rhyme is the repetition of certain sounds of the words, again from the same line of "The Raven," the rhymes are shown bold:

Once upon a midnight dreary, while I pondered, weak and weary

Repetition is repeating of word phrases or single words:

As of some one gently rapping, rapping at my chamber door...

d) Alliteration is the repition of consonant sounds:

Once upon a midnight dreary, while I pondered, weak and weary,

Assonance is repition of vowel sounds:

But the silence was unbrOken, and stillness gave nO tOken,

and the Only word there spoken was the whispered word,

LenOre:

And so the devices that are not word music are: c) simile and metaphor. Neither of these devices relies on sound. They rely on comparisons of meaning. "His hair was like steel wool" is a simile. "The old ship was a was a bucket of rust" is a metaphor. No music is needed for them.
