Polifonia fortepianu

W świecie akustycznym i powiedzmy klasycznym, polifonia ma zupełnie inne znaczenie. Nie jest bezpośrednio definiowana jako po prostu liczba jednocześnie zagranych nut. Po angielsku jest hasło "Polyphony and monophony in instruments" i tam jest fajny akapit, w ogóle fajnie opracowane hasło:

In classical music, a definition of polyphony does not only mean just playing multiple notes at once but an ability to make audiences perceive multiple lines of melodies. Playing multiple notes as a whole such a rhythm from a chord pattern is not polyphony but homophony. Therefore, polyphony in classical music is a technique to describe clavier ways of using a less number of sources to produce a more number of sounds rather than just increasing a new mechanical to produce notes in new instruments which is not efficient as a sound perception of human has its limitation to tracking multiple sources (auditory scene analysis and lossy compression such as mp3 might explain this phenomenon) and usually associated with counter point theory. Moreover, the sounds generate by instruments does not have only notes and dynamics but tone colors. Some instruments produce more tone colors via even a single note but some play multiples notes with less variations of the tone colors. Some instruments can give clear variations of articulations than others but some do not. Thus, classical polyphony cannot directly be considered by just a number of simultaneously playing notes.
