  • Your robot can play a note by “beeping”

  • Every note in music has a “frequency”

    • Physics of Frequencies:

      (http://www.phy.mtu.edu/~suits/notefreqs.html)

  • Notes can be controlled by beeping the correct frequency.

    • beep(1, 440) -- Beep note A4 (That’s an “A” in the 4th octave)

Scribbler Music

  • Programming music by frequency is difficult!

    • It’s a lot of numbers!

  • Scribbler has set of functions that help go from notes to frequencies.

  • Scribbler has a range of 8 octaves (same as a piano)

  • Scribbler has all the notes. They are denoted:

    C C#/Db D D#/Eb E F F#/Gb G G#/Ab A A#/Bb B

Scribbler Robots can play 2 notes simultaneously. Simply list the 2 notes on the line.

  • Once you have the notes you need to add the timing. A whole note is 1 and half note is .5, etc.

  • Normally a whole note is about .5 secs. You can change the tempo but sending a parameter in playSong() function.

  • Now take the notes and the timing and you create a song!

  • Listen…
