String Quartet Pi / Music of Pi / Kenji Kojima


	OVERVIEW: String Quartet Pi / Kenji Kojima • The music was created from the constant π (Pi) to 3,000 decimal places. I believed many artists and scientists have tried same idea before. I should rather say “String Quartet Pi” was one of interpretations of Pi music. The constant was always same, however as the result of each music by an interpretation was accompany sense of beauty of composers. One of purposes of this creation was beyond human being performance. I hope you can enjoy the music and the reading process of the data. 2004, Kenji Kojima • Click on the top-left of QuickTime controller and listen it. A SEED OF THE MUSIC:* • The constant Pi is used from the first number 3 to until under the point 3,000 decimal places. MUSICAL NOTATION / PROGRAMMING: • The score adopted with same musical notation that was play command of HyperTalk a script language of Apple’s HyperCard. And it was extended to other MIDI functions that was PMD (Play Midi Data). A number plus one is a step of chromatic scale is upped. For Ex. If the number 3 is C, 4 is C#. The center C is set to the absolute pitch 60 for the application player* which plays MIDI instruments by numeric steps. C# that is next of center C is absolute pitch 61. Next D is 62. TEMPO / PROGRAMMING: • The first number 3 of Pi is played by tempo 31 on this music and after that a whole rest is placed, then the next number of Pi that is 1 is played by tempo 32, and after each number increments the tempo by 1. The last number of this pi music is played by tempo 3031. After every each one hundred numbers are played, 5 whole rests are placed. And the next one hundred numbers are played again. INSTRUMENTS / PROGRAMMING: • The instruments are MIDI Contrabass, MIDI Cello, MIDI Viola and MIDI Violin. Contrabass part plays the first number "3" of Pi for C2 (C4 is center C). Cello part plays the first number "3" of Pi for D#3, Viola part plays G4 and Violin part plays A5. The scores for each instrumental were created by Transcript that is a language of Runtime Revolution. PLAY / CREATE AIFF: • AIFF files for each instruments were created from the scores by the application “LoopNoMoto” that was developed by Kenji Kojima who was the author of this music. “LoopNoMoto” plays Center C for 60 by numeric steps. ARRANGEMENT: • Four AIFF files of each instruments were mixed and arranged in Apple GarageBand and made the final music file. Pi: Resources 1), 2) PMD and a library of makeSMF (Standard Midi File) were made by UDI. http://homepage.mac.com/udi/ The application player: “LoopNoMoto” was developed by Kenji Kojima who was the author of this.
