|Step_Content=<translate><!--T:29-->
The activity consists in turning fruits into a keyboard to play music with.

<!--T:30-->
To get started, plug the makey makey (or DIY makey makey with Arduino Leonardo) to your computer and connect all bananas (or other conductive items) to the board via alligator clips.</translate>

|Step_Content=<translate><!--T:60-->
Each fruit is connected to makey makey arrows, space or click buttons.

<!--T:61-->
We will start by using these 5 keys.

<!--T:62-->
You can now launch scratch and start writing your code. To start with, go to “Events” (light brown) section.</translate>

Next pick the “when green flag clicked” and the “forever” block.

<!--T:64-->
In order to create an action, choose the “if then” block from the Control category.</translate>

“If then”, is the most common function used in coding and is used to create an interaction between your code and the outside world.

<!--T:66-->
Since the activity consists in creating a piano we would like that sounds were triggered when a certain key were pressed.Under the sensing section, you will find the “Key _ pressed?” block.

<!--T:67-->
Click on the small black arrow and select the key you need.

<!--T:68-->
We have a condition (If then), we have chosen a key, we only need to add a sound.</translate>

|Step_Content=<translate><!--T:72-->
You now need to add extra keys in order to have more piano notes altogether.

<!--T:73-->
Right click on the “If then” block and a small menu will pop up. Click on “duplicate” and paste it below the first conditional. Repeat the operation for each key.</translate>

|Step_Content=<translate><!--T:74--> Your piano is now ready, you just need to tune it ! You need to determine the exact sound of each note. By clicking on each note, a small keyboard will pop up, which will enable you to select the note that you are looking for.</translate>

The Piano sounds funny? It’s perfectly normal! some chords played together sound well and some other don’t… So it’s time for a little bit of music theory, don’t be scared it will be fast and fun.

<!--T:76-->
Here is an example of how different cords can produce different feelings depending on the order in which they are played: [https://en.wikipedia.org/wiki/I%E2%80%93V%E2%80%93vi%E2%80%93IV_progression https://en.wikipedia.org/wiki/I%E2%80%93V%E2%80%9...]

Other happy chords?

<!--T:79-->
Do you want to change instrument?

<!--T:80-->
It’s easy in Scratch. You can find plenty of instruments available in a list located in the Sound (purple) section.</translate>

Example of a finished code:

<!--T:82-->
To go further...This code is using 4 chords and one key for change instrument. The same like a piano use pedal for change the tuning, if one key (space in this case) is pressed the code play the sound of a ‘guitar’ and when the key is released the sound is the one of ‘lead synth’.

<!--T:83-->
Now you have the possibility to create a more interesting instrument. In the next lessons you will discover the Operator (light green) section, and add more possibilities and effects.

<!--T:84-->
Stay tuned ;-)</translate>
