Doodles are the fun, surprising and sometimes spontaneous changes that are made to the Google logo to celebrate holidays, anniversaries and the lives of famous artists, pioneers and scientists.
Today's doodle is related to Bartoloemo Cristofori, an Italian musical instrument maker credited with inventing the pianoforte, or: the piano. One of his biggest innovations was creating a hammer mechanism that
struck the strings on a keyboard to create sound. The use of a hammer
made it possible to produce softer or louder sounds depending upon how
light or hard a player pressed on the keys. In fact, that’s how
Cristofori’s new instrument got its name -- in Italian, piano means
soft, while forte means loud. Being able to change the volume was a
major breakthrough. And that’s exactly what Doodler Leon Hong wanted to
highlight in his interactive Doodle.
By the way, the melody is from Johann Sebastian Bach's Jesu, Joy of Man's Desiring.
