troubách

Troubách is the locative plural form of the Czech feminine noun trouba, which denotes a trumpet or, in brass sections, a trumpet-like instrument. In Czech grammar, feminine nouns ending in -a often form the locative plural with the ending -ách; troubách is used after prepositions that govern the locative, such as v (in), o (about), or na (on/about). As such, troubách functions as a grammatical form rather than a standalone lexical item.

Usage notes: The form appears mainly in musical or formal texts—orchestra programs, musicology, or descriptive passages about brass sections. It is uncommon in casual conversation, except when specifically discussing trumpets or orchestral arrangement. The word should be distinguished from singular and plural nominatives trouba and trouby, which refer to the instrument or to a trumpet group in their respective cases.

Examples: In Czech, one might encounter phrases such as “V troubách zněla výrazná melodie.” or “O troubách se psalo v soupisu nástrojů.” These illustrate how troubách marks location or topic with a clear reference to trumpets within a discourse on orchestration.
