This is a pair-programming assignment (i.e., you may work with one partner). You may discuss the assignment only with your partner or the instructor.
This assignment focuses on:
- creating interesting music with jMusic
- MIDI melodies
- MIDI percussion
In class we worked through several programs that put all jMusic data structures into practice (see Ch2 of the jMusic book). We looked at:
- a program that creates a drum pattern consisting of kick, snare and hi-hat sounds;
- a program that creates a canon; and
- a program that creates a minimalist piece (Piano Phase by Steve Reich).
As mentioned earlier, MIDI has 16 channels (numbered 0 to 15). Of these, channel 9 is reserved for percussion. When adding notes to a part assigned to channel 9, the pitch of the notes determines which percussive instrument to use. Again, here are pitch numbers for some percussive instruments:
- 36 (C2) -- Bass Drum
- 38 (D2) -- Snare Drum
- 42 (FS2) -- Hi Hat (closed)
- 46 (AS2) -- Hi Hat (open)
- 49 (DF3) -- Crash Cymbal
Here are more pitch numbers for percussive instruments.
Write a Jython program that generates an interesting piece of music. You have two options:
- Find an interesting minimalist piece (e.g., by Philip Glass), and work with it in jMusic.
- Or, create your own song in jMusic. If so, the song needs to have both a melody and drums (all done in MIDI via jMusic).
Here is a quick overview of music notation for note pitches.
Here is a quick overview of music notation for note durations (rhythm values).
- jMusic defines the following note durations for convenience.
- It includes both American and British names. For example,
- whole note = semibreve
- half note = minim
- quarter note = crochet
- eighth note = quaver
jMusic provides the following MIDI Instruments.
Follow the Golden Rule of Style: "A program should be as easy for a human being to read and understand as it is for a computer to execute." 
In general, you should comment any variable, obscure statement, block of code, etc. you create.
Additionally, your code should always include opening comments as follows:
# Author: <Your Name(s)>
# Email: <Your email address(es)>
# Class: CSCI 180, Section 1
# Assignment: HMWK2
# Due Date: <The assignment's due date>
# Certification of Authenticity <remove one of the following>:
# I certify that this lab is entirely my own work.
# I certify that this lab is my own work, but I received
# some assistance from: <Name(s)>
# Purpose: <Provide a simple, yet complete description of the task being
# performed by this program. It may be several sentences long.>
You will submit your assignment via WebCT. Be prepared to demo your music to the rest of the class. Your submission consists of:
- Your Python program. Give it a meaningful name.
- The MIDI file generated from your program.
Your grade will be based on how well you followed the above instructions, and the depth/quality of your work.
