Final answer:
The relationship between melody and accompaniment in a piece of music can vary widely depending on the style and genre of the music.
Step-by-step explanation:
The relationship between melody and accompaniment in a piece of music can vary widely depending on the style and genre of the music. In some cases, the melody may be predominantly in the upper voice, while the accompaniment is in the lower voice. However, this is not always the case.
For example, in a classical symphony, the melody may be passed between different voices or instruments throughout the piece. In a jazz piece, the melody may be played by the trumpet while the accompaniment is played by a piano and bass.
Therefore, it is not accurate to say that the melody is always in the upper voice or that the accompaniment is always in the lower voice. The relationship between melody and accompaniment is determined by the specific composition and the artistic choices of the composer.
