Last night, I was startled by a sudden explosion sound.

A wonderful sound flowed from his piano.

He is good at playing the piano, and has a very good sense of sound.

Devon is my best friend.

His range is very wide.

He practices every day to learn the correct Chinese pronunciation of characters.

His piano performance was skillfully woven with mordents.

He is an expert in musicology.

In phonetics, a phone represents a single sound.

The transcription of this movie is very excellent.
