The name of this American composer and at the same time
pianist is George Gershwin. He wrote the orchestral compositions like Rhapsody
in Blue in 1924 and An American in Paris in 1928. In 1935, he also made the
Porgy and Bess which was an opera piece. At first he was well known as a song
plugger but later he began composing for Broadway theatrical works with Ira
Gershwin, his brother, and Buddy DeSylva. His works were performed by many singers and
artists. His compositions have been used and adapted in numerous films and for
television too. His works became jazz standards and were also recorded in many
variations.
It is the interaction between different notes played together that gives music its richness and color. Playing more than one note at the same time is called harmony. The difference in the pitch between two notes is called their interval, a word we used earlier to describe the separation of notes in the Major scale.
