10.02 Assignment Instructions
Purpose: Play a song translated into the MIDI protocol.
Materials: PlaySongDemo.zip (../../zip/PlaySongDemo.zip) and sheet music for a song of your choice.
Program Specifications: Use the following guidelines to write your program.
1. Locate a web site with copyright free sheet music for a song of your choice, or use one of the
following.
National Anthem of the United States (../../pop/10_02_04/10_02_04_pop03.htm)
Pop Goes the Weasel (../../pop/10_02_04/10_02_04_pop04.htm)
Londonerry Air (../../pop/10_02_04/10_02_04_pop05.htm)
2. Write the names of the notes in the song above each line of music (e.g., C, G, etc.).
3. Convert name of the note to its corresponding MIDI note number
(//l.flvsgl.com/GSL0ca44dd5d11e2306425bf988e09c05a6c) for each line of music (e.g., middle C =
60).
4. Record the duration of each note using 1000 for whole notes, 500 for half notes, 250 for quarter
notes, 125 for eighth notes, and 62 for sixteenth notes.
5. Make a copy of the PlaySongDemo and rename it PlayMySong.
6. Assign the MIDI note numbers to the notes[ ] array.
7. Assign the MIDI duration numbers to the duration[ ] array.
8. Choose an instrument from those listed in the documentation at the beginning of the MidiPlayer
class (e.g., FLUTE, PIANO, etc.). Assign the instrument constant as the parameter in the
setInstrument() method.
9. Be sure to add applause at the end of your performance.
Expected Output: When your program runs correctly it will play the melody of the song you transcribed
into the MIDI format.
Analysis Questions: Please answer the following questions.
1. What are some similarities and differences between playing music and writing a program?
2. Which instrument did you like the best and why?
3. What question(s) of your own did you answer while writing this program?
4. What unanswered question(s) do you have after writing this program?
Optional Collaborative Assignment Specifications: Use the following guidelines to complete the
collaborative extension to this assignment. Several collaborative opportunities are provided throughout the
course, but you only need to complete one.
1. Notify your instructor that you need partners for this collaborative assignment. Tell your instructor
whether you read music or not. While you are waiting for partners to be assigned, continue on to the
next assignment.

2. When your instructor matches you up with other students, contact your partners and introduce
yourself. When possible, a team will consist of at least two students who read music and one who
does not.
3. Work together with your partners and choose a different song to program. Locate the sheet music
for the song, but remember it must not be copyrighted.
4. Next, decide among yourselves who will transcribe the music and who will mix the voices.
Student A - First Transcriber: Transcribe one voice of the song into the MIDI format. Begin the
song with a whole rest, a middle C quarter note, and another whole rest to provide a
synchronization point. Test your transcription with your program for this assignment to make
sure it plays correctly. Send program to Student C.
Student B - Second Transcriber: Transcribe a different voice of the song into the MIDI format.
Begin the song with a whole rest, a middle C quarter note, and another whole rest to provide
a synchronization point. Test your transcription with your program for this assignment to
make sure it plays correctly. Send program to Student C.
Student C - Mixer. Download the Quick Start Audacity Instructions to your Mod10
Documents folder. Follow the instructions and set up Audacity on your computer.
Run the program received from Student A and capture an audio recording of the song
with Audacity.
Run the program received from Student B and capture an audio recording of the song
with Audacity.
Use the middle C quarter note at the beginning of each song file to synchronize the
separate voices. After the voices are synchronized, delete the synchronization point
and export the audio file in the mp3 format. Send the mp3 file to your partners.
5. Your work will be submitted through as 10.05 Collaborative Project. Each student will submit a copy
of the program and the mp3 audio file as well as the Self-Assessment Collaboration Survey.
