Final answer:
In a homophonic texture, the focus is on the melody, which is the dominant musical line over the harmonious accompaniment. The loudness of sound is described by intensity level or decibel. Sound is produced by objects like tuning forks and violin strings because of their vibration.
Step-by-step explanation:
In a homophonic texture, the attention is focused on the melody. This is the dominant musical line that stands out over the accompanying parts. Homophonic texture often features harmony, where the accompanying parts support the melody by providing chords or chordal accompaniment. Despite the presence of harmony, it is not the focal point; rather, it enhances the primary melody.
Answering the related questions, the word or phrase used to describe the loudness of sound is intensity level or decibel (b). Loudness is determined by the amplitude of the sound waves, and decibels are the units of measurement. As for the second question, a tuning fork, a violin string, and a loudspeaker are all producing sounds because they are in a state of vibration (A).
