Answer:1.Mono is short for monophonic, meaning one sound. Mono sound is any sound – in most cases, music, that is recorded and or played back using one audio channel. For example, one microphone recording a guitar is a mono recording, because you're using one channel (with one mic) to pick up the sound of the guitar.
2.Homophonic music can also be called homophony. More informally, people who are describing homophonic music may mention chords, accompaniment, harmony or harmonies. Homophony has one clear melodic line; it's the line that naturally draws your attention. All other parts provide accompaniment or fill in the chords. Homophonic texture is the most common texture in Western music. ... So, a homophonic texture is where you can have multiple different notes playing, but they're all based around the same melody. A rock or pop star singing a song while playing guitar or piano at the same time is an example of homophonic texture.
3. Polyphony, in music, the simultaneous combination of two or more tones or melodic lines (the term derives from the Greek word for “many sounds”). Thus, even a single interval made up of two simultaneous tones or a chord of three simultaneous tones is rudimentarily polyphonic. Examples of Polyphony
Examples of PolyphonyRounds, canons, and fugues are all polyphonic. (Even if there is only one melody, if different people are singing or playing it at different times, the parts sound independent.) ... Music that is mostly homophonic can become temporarily polyphonic if an independent countermelody is added
