Welcome to Music Blocks! The first thing you need to know about Music Blocks is the mouse at the center of the screen is the performer, Mr. Mouse. Mr. Mouse performs whatever is in the Start block. You can think of the Start block as a kind of performance script (or sheet music).
You can have Mr. Mouse perform the script by clicking on the Start Block. You can also have Mr. Mouse perform the script by clicking the run arrow at the top-left of the screen.
Go ahead and click on the run button and listen to Mr. Mouse perform his script. What do you hear?
