Intervallic → It is formed from "inter-" (meaning between) and "vallis" (from Latin, meaning valley). The word describes something that occurs in the spaces or valleys between notes or sounds, particularly in music.
Think of things that happen 'between' ('inter-') 'valleys' ('vallis') — that's why intervallic refers to the spaces between musical notes.
