// Using Material and Lighting to produce a creative scene

// My scene will be the start of my final project. 

// For the project I want to
// create a jazz club, with an audience sitting at candlelit tables and 
// sipping wine while watching a jazz band play. The jazz band will be onstage,
// a pianist, sax and bass players,and a diva singing.

// My scene now will be a table with the saxophone on it.
