What can be inferred about sound frequencies related to music?

Sound frequencies in music encompass a wide range that includes both low and high frequencies. Music is created by vibrations that produce sound waves, which are characterized by their frequency, measured in hertz (Hz). Low frequencies correspond to bass sounds, which provide depth and richness, while high frequencies relate to treble sounds, which contribute brightness and clarity to the music.

The inclusion of both low and high frequencies is essential for a complete musical experience, as different instruments and vocal ranges produce sounds across this spectrum. For instance, a piano can produce a wide range of notes, with bass notes in the lower frequencies and treble notes in the higher frequencies. This diversity in frequency enhances the texture and complexity of musical compositions, making option B the most accurate reflection of sound frequencies in music.

Other choices do not accurately represent the nature of sound frequencies. High frequencies alone do not encompass the full array necessary for musical richness, nor is frequency solely dependent on instrument types, since within any given instrument, a variety of frequencies can occur. Additionally, sound frequencies can vary widely across music genres, instrumentation, and individual compositions, contradicting the idea that they cannot vary greatly.
