People tend to associate accents with peoples or regions they do or don't like. The sound of the accent isn't the culprit. A crying baby usually needs something. A grating sound gets our attention. Helping the baby may cease its crying.
Musicians distinguish between noise and a tone.
A tone stands by itself. A noise depends on what makes the noise. Water dripping into a quiet pool soothes us but from a leaky faucet does not. An instrument yields a musical sound if it produces periodic vibrations . The strings of a violin or the lips of a trumpet player can make noise or music depending upon whether the sound is periodic.
