1. Round songs and cannons produce polyphony, which is the interaction of two or more independent melodic lines. In polyphony, each voice or instrument has its own melody that contributes to the overall musical texture. This creates a rich and complex sound where different melodies intertwine harmoniously. Examples of polyphonic music include fugues by Johann Sebastian Bach and works by composers like Palestrina.
2. Solo voice does not help in identifying the texture in music as texture refers to how the melodic, rhythmic, and harmonic elements are combined in a piece of music. Whether a piece is monophonic, homophonic, or polyphonic depends on the interplay of these elements rather than the number of voices or instruments performing.
3. The simplest texture consisting of a melody typically sung by a singer accompanied by an instrument is known as monophonic texture. In monophony, there is a single melodic line without any harmony or accompaniment. This texture is often found in chants, folk songs, and early music where a solo voice carries the main musical material without additional layers of harmony.
