To make a loud, harsh sound, especially of horns, sirens, or music. Can also mean to proclaim loudly and harshly.
From Middle English blaren, possibly imitative of loud sound. Related to Middle Low German blāren meaning 'to bleat or cry.' The word evolved from animal sounds to describe any loud, unpleasant noise.
The word 'blare' is beautifully onomatopoeic - it actually sounds like what it describes! When you say it forcefully, your mouth naturally opens wide and projects sound forward, mimicking the very action of blaring.
