Perl Jam

Perl Jam

• Music In The Key Of Perl

2
What I wanted To Do

• Create a computer program that would create an
  audio file (midi, wav, etc) of randomly generated
  Jazz music
• Essentially pick instruments and have the program
  select random notes with random durations for the
  different instruments
• Have it work on my Mac Mini with little or no
  extra hardware

My Inspiration

• Some computer science professor at RIT, who was
  also a Jazz trumpet player
• He created a program to serve as his band
• He was able to trade solos with the computer

• Q Why Jazz? Isnt that for old people?!
• A NO!!!

Why Jazz?!

• I like it
• Improvisation plays a large part
• A major component of Jazz is the jam session

Creating Music With Perl

• Modules
• MIDIPerl (read, compose, modify, and write MIDI
  files)
• MIDISimple (interface for MIDI composition)
• MIDIMusic (Perl interface to /dev/music)
• MIDIRealtime (Writes MIDI data to
  /dev/sequencer in real time)

Creating Music With Perl

• I ran across an article from Perl.com on someone
  who was creating and performing live music with
  Perl
