# happy birthday blocks challenges

Coding challenges for finishing the song, happy birthday.

## Before we get started

Complete the [happy birthday](/lessons/happy-birthday/activity) activity and your code will look like this:


```blocks
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.D), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.E), music.beat(BeatFraction.Quater));
basic.pause(100);
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.D), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.G), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
basic.pause(100);


```

### Challenge 1

Let's code the third part of Happy Birthday!

To do this, you need to add blocks after the last line of the `play` blocks. We want to continue to adding musical chords with the `play` block. Then insert the appropriate chord blocks `G`, `E`, `C`, `B`, `A` to complete the third part of the song. Modify your code so that your code looks like this.

``` blocks

music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.D), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.E), music.beat(BeatFraction.Quater));
basic.pause(100);
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.D), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.G), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
basic.pause(100);
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.A), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.E), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.D), music.beat(BeatFraction.Quater));
basic.pause(100);

```

### Challenge 2

Finally, we continue to adding the appropriate `play` block and fit the following chords blocks `F`, `E`, `C`, `D` to complete the third part of the song. Modify your code so that your code looks like this.


```blocks
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.D), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.E), music.beat(BeatFraction.Quater));
basic.pause(100);
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.D), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.G), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
basic.pause(100);
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.A), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.E), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.D), music.beat(BeatFraction.Quater));
basic.pause(100);
music.playTone(music.noteFrequency(Note.A), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.A), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.B), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.G), music.beat(BeatFraction.Quater));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
```
