The collection begins with Wolfgang Amadeus Mozart and his masterpiece Symphony No. 40.  Mozart was designed to be the first aspect of this particular collection because he is probably the most famous name to come out of the Classical Period of music.  He is accompanied by a photograph of the composition of his famous Symphony No. 40 because that symphony meant so much to what Mozart brought to the Classical Period in terms of music.  Mozart may have been a master at his craft, but he was not the "Father," which brings me to my next point.

The middle section of the collection contains a painting of Franz Joseph Haydn who was one of the most influential names in music during the Classical Period as he had a lot to do with the transition into the Classical Period from the previous Baroque Period.  Haydn is accompanied by a photograph of one of his more famous piano trio composition as a composer.  Haydn was nicknamed the "Father of Symphony" and "Father of the String Quartet."  Symphony and string quartet are two of the few things Haydn brought to music during the time period, as well as chamber music and the piano trio.

The final section of the collection contains a painting of Ludwig van Beethoven who was one of, if not the very most famous composer (as well as being a pianist) from the Classical Period of Music.  Beethoven was the main driving force at the end of this musical era as he was such a pivotal aspect of the transition into the later Romantic Period.  Beethoven's portrait is accompanied with one of his most famous composition of Symphony No. 5.  If someone says they haven't heard Beethoven's 5th Symphony, throw it on your phone's playlist and let them listen, I'm sure they've heard it.  The symphony is wildly famous and so is the deaf man that wrote it.
