+Control images with variables. 
+
+Have you ever tried to making beat box sounds? Let's try making a beatbox with code!
+
+Let's start by adding a variable where you can store data. Then rename the variable to "sound". Then set the value of the variable to the note block `A` from the Music drawer. Modify your code so that your code looks like this.
+
+```blocks
+let sound = music.noteFrequency(Note.A);
+```
+
+We want to play music on pin pressed in order to register an event handler that will execute whenever when you run a script and click pin 1 on the simulator. We must start by opening the Input drawer and adding `on pin pressed` P1. Modify your code so that your code looks like this.
+
+```blocks
+let sound = music.noteFrequency(Note.A);
+input.onPinPressed(TouchPin.P1, () => {
+
+})
+```
+
+We want to code the notes that will be played `on pin pressed`. We click on the Input drawer then insert a `for loop` that will increment by *i*. Click on the Variables drawer. Add `set item` block. Rename the variable block to "sound." Then add a Maths block to increase the variable sound from the note frequency of block `A` to `A` plus 25.Modify your code so that your code looks like this
+
+```blocks
+let sound = music.noteFrequency(Note.A);
+input.onPinPressed(TouchPin.P1, () => {
+    for (let i = 0; i < 4; i++) {
+        sound = sound + 25
+    }
+})
+```
+
+Include a play block with the variable called "sound" and insert a music note block `1/16`. Modify your code so that your code looks like this
+
+```blocks
+let sound = music.noteFrequency(Note.A);
+input.onPinPressed(TouchPin.P1, () => {
+    for (let i = 0; i < 5; i++) {
+        sound = sound + 25
+        music.playTone(music.noteFrequency(sound), music.beat(BeatFraction.Sixteenth));
+    }
+
+})
+
+```
+
+
+* click *run* to see if the code works as expected.

+# beatbox challenges
+
+Create sounds with variables.
+
+## Before we get started
+
+Complete the [beatbox](/lessons/classic-beatbox/activity) activity and your code will look like this:
+
+
+```blocks
+let sound = music.noteFrequency(Note.A);
+input.onPinPressed(TouchPin.P1, () => {
+    for (let i = 0; i < 4; i++) {
+        sound = sound + 25
+         music.playTone(music.noteFrequency(sound), music.beat(BeatFraction.Sixteenth));
+    }
+})
+```
+
+### Challenge 1
+
+Let's include a second sound `on pin pressed` *P2*. To do this, you need to add the same blocks as the banana keyboard activity. However, you must change alter `on pin pressed` from P1 to P2. Additionally, you must *decrease* the frequency of the variable "sound" by 25. Modify your code so that your code looks like this
+
+
+```blocks
+let sound = music.noteFrequency(Note.A);
+input.onPinPressed(TouchPin.P1, () => {
+    for (let i = 0; i < 5; i++) {
+        sound = sound + 25
+        music.playTone(music.noteFrequency(sound), music.beat(BeatFraction.Sixteenth));
+    }
+
+})
+input.onPinPressed(TouchPin.P2, () => {
+    for (let i = 0; i < 5; i++) {
+        sound = sound - 25
+        music.playTone(music.noteFrequency(sound), music.beat(BeatFraction.Sixteenth));
+    }
+
+})
+```
+
+* click *run* to see if the code works as expected.
+
+### Challenge 2
+
+Finally, we want images to be displayed with sounds `on pin pressed`. Add `show LEDs` blocks under `on pin pressed` P1 and P2.
