Scribbler Music Web Design
Notes • 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

Simply list the 2 notes on the line.
Songs… • 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…
