=== Trills ===
[[Trill (music)|Trills]], though generally simple with valves, are difficult on the slide trombone. Trills tend to be easiest and most effective higher in the harmonic series because the distance between notes is much smaller and slide movement is minimal. For example, a trill on B{{music|b}}<sub>3</sub>/C<sub>4</sub> is virtually impossible as the slide must move two positions (either 1st-to-3rd or 5th-to-3rd), however at an octave higher (B{{music|b}}<sub>4</sub>/C<sub>5</sub>) the notes can both be achieved in 1st position as a lip trill. Thus, the most convincing trills tend to be above the first octave and a half of the tenor's [[range (music)|range]].{{sfn|Herbert|2006|p=43}} Trills are most commonly found in early Baroque and Classical music for the trombone as a means of ornamentation, however, some more modern pieces will call for trills as well.
