<span>I do agree with the author for the simple fact that looking at a imagine can change your mood. Not everyone's opinion of what art truly is can be the same. We call come from different backgrounds, experiences, situations, etc, that can influence how we think of what art truly is. Picasso's piece for me is happiness but to someone else to could mean dark, messy. Everyone's brain are wired the same but the other things like experiences make to you what is really beautiful, sad, or even ugly.</span>
Answer: Cowell
Explanation:
The first one who experimented with piano strings and clusters is Henry Cowell.
He was the first one who asked the pianist to manipulate string and then when he discovered the sound.
Before that new sound, he discovered also <u>tone clusters</u>. Tone clusters were achieved by hitting the piano keys with elbows or fists.
