Texture
In music, we can talk about the texture of a piece of music.  If there are a lot of notes being played at once, we could call this a “thick” texture.  If there are just two or three notes being played so that every note can be heard clearly, we could call this a “thin” or “clear” texture.  Music may have a “polyphonic” texture or a “chordal” texture.  The word “texture”, this time, is being used to describe something we hear instead of something we feel.
