IPA: /ˌdaɪəˈpeɪsən/
KK: /daɪəˈpeɪsən/
A full and rich sound, often used to describe music or the range of notes an instrument can produce.
The choir's performance was filled with a beautiful diapason that resonated throughout the hall.
Diapason → It is formed from "dia-" (meaning through or across) and "paso" (from Greek "paso", meaning step or measure). The term originally referred to the full range of musical pitches, as it encompasses all steps or measures across an octave.
Think of 'across' ('dia-') and 'steps' ('paso') to remember that 'diapason' refers to the full range of musical notes.
