Many modern will often use pen and ink as their main medium. In history most used paint, like for the stunning Mona Lisa. However, in a long time ago, most artists did not use ink. Maybe because they thought ink would look sketchy. Back then, most people did not like sketchy art, be in the modern world, now we do.
Hope this helps!

A place where music is performed is: an <u><em>Auditorium.</em></u>
It starts slowly, with only a few instruments. Gradually speeds up the tempo, gradually gets louder, adding more instruments....but the same tune is repeated over and over again. The single the,e achieves unity. The tempo and dynamic changes (Loudness, speed) give is the variety.
