A mordent is a single note trill. It is indicated by a zig-zig over a note. The trumpeter should play the indicated note, raise it one step, and then return to the first pitch and hold it.All of this takes place very quickly.
Ornamentation of a melodic note by playing the melodic note and adding a single rapid note a minor second below for a lower mordent and the note a minor second above for an upper mordent.
A musical ornament in two forms (lower and upper). The name comes from the Italian mordere meaning "to bite". An extra initial (lower or higher) note is played almost simultaneously before the main note.
'Biting.' An ornament consisting of an alteration (once or twice) of the written note by playing the one immediately below it (lower mordent), or above it (upper, or inverted, mordent) and then playing the note again.
