Dissonant

Contemporary classical music is often very dissonant.

"Their music is strident and grating." "The word is 'dissonant.'"

The music was filled with dissonant chords.

Alaudinov's framing of himself, and by extension of the Chechen forces under his command, as a capable defensive body is also dissonant with the widespread perception of the efficacy of Chechen forces within the wider Russian information space.
