Polytonalitet

**Polytonalitet** er bruken av flere tonearter samtidig innen musikk. Når det er snakk om akkurat to tonearter samtidig, benytter en ofte betegnelsen **bitonalitet**. Et velkjent eksempel på dette finnes i balletten Petrusjka av Igor Stravinskij. I den andre delen blir det spilt en fanfare der førsteklarinetten spiller en melodi på tonene i en C-durakkord, mens andreklarinetten spiller den samme melodien på tonene i en F#-durakkord. Her låter det dissonerende, men polytonalitet kan i andre tilfelle også konsonere.
