Select the yellow x sprite.

Tempo is the speed or pace of a piece of music, changing tempo of the music of your art piece plays, using the change tempo by block.

Drag out a change tempo by block, and place it in the conditional of your co stack, beneath the play note block.

Now, when this sprite touches the color green, it will play note 52 for .5 beats, then change tempo by 20.

The speed or pace of the note being played should increase, test it out and see what happens.

if you wanna slow down the pace of your music, you can always change the value 20 to a negative number, like -20.

Tinker with the values to make your program change the tempo of the music being played.

You can also change the instrument that is playing the note in your project, to do that use the set instrument to block.

Drag out a set instrument to block, and place it in the second conditional in your code stack, above the play note block.

Click on the drop down main to see the different instruments included in scratch.

There are about 21 different instruments to choose from.

To play around an instrument each time the sprite touches a particular color, for example orange you need a pick random block.

Go to the operators menu, drag out a pick random one to 10 block, and place it inside the value bubble of the set instrument to block.

Since there are 21 instruments in scratch, change the values in the pick random block to pick from one to 21, so that each time the block runs, it chooses a different or random instrument, test out your code to see what happens.

When the sprite touches orange, the instrument playing the note changes, cool.

Now it's your turn, use the change tempo by block to change the tempo of the music.

Use the set instrument to and pick random blocks to make the instrument change when the sprite touches a particular color.

And lastly, tinker with the values and placement of these blocks, until you find something you like.
