happy birthday blocks activity

Play sounds with music blocks.

Have you ever tried to play a song on an instrument? Let's try coding the song "Happy Birthday" on the @boardname@ !

Let's start by adding the code in the music drawer that includes a single musical chord (or pitched sound) with the play block. Then insert the chord "C". Once you are done coding, don't forget to run your code in the simulator or the @boardname@.

music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quarter));
  • click run to see if the code works as expected.

We want to continue to adding musical chords with the play block. So insert the appropriate chord blocks: D, F, G to complete the first part of the song. Modify your code so that your code looks like this.

music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quarter));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quarter));
music.playTone(music.noteFrequency(Note.D), music.beat(BeatFraction.Quarter));
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quarter));
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quarter));
music.playTone(music.noteFrequency(Note.E), music.beat(BeatFraction.Quarter));
basic.pause(100);
  • click run to see if the code works as expected.
