IPA: //ˈsɛmɪˌbriːv//
KK: /ˈsɛmɪˌbriv/
A whole note in music that lasts for four beats in common time.
In the piece, the composer used a semibreve to hold the note for a full measure.
**Semibreve** → It is formed from "semi-" (meaning half) and "brevis" (meaning short). The word "semibreve" refers to a musical note that is half the length of a breve, or a whole note, hence the name half short.
Think of 'semi-' meaning half and 'brevis' meaning short — a semibreve is a note that is half the length of a whole note.
