Final answer:
The phrase 'A consonant rhythm' doesn't make sense because consonance typically refers to harmony, not rhythm. In music, consonance and dissonance usually refer to intervals and chords rather than rhythmic patterns.
Step-by-step explanation:
The phrase that doesn't make any sense is A) A consonant rhythm. Music terminology includes phrases like fast melody, open texture, and dissonant harmony which are all coherent within the context of music theory. However, the term consonant rhythm is not typically used and doesn't align with standard musical terminology. Consonance refers to agreement in music, typically dealing with harmony rather than rhythm. Rhythm, referenced as the "heartbeat" of language or music, relates to the time aspect of music and doesn't inherently possess a consonance or dissonance. Dissonance generally applies to harmonies or intervals that sound unresolved or create a sense of tension.
When discussing music, elements like amplitude might refer to the loudness, which is similarly described by terms like intensity level or decibel. Frequency affects the perceived pitch of a sound, and the differences in frequency between two notes played together will determine the beat frequencies produced.
