Scribbler Music

1. Scribbler Music Web Design

2. Notes • Your robot can play music by “beeping” the correct notes. • 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

3. Scribbler Music • Programming music by frequency is difficult! • 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

5. Songs… • Once you have the notes you need to add the timing. Easiest is to default a whole note to 1 and the .5 for half note, etc. • Now you create a song!
