Shogi Composition is a kind of recipe for collaborative composition 
among various people with different musical backgrounds and various 
musical abilities.  It is just like playing cards around a table.  A few 
players around a table compose short passages one after another instead 
of playing cards.  Please enjoy it and compose new interesting music!

1) The number of players
   In order to do Shogi Composition at least 2 players are required.  
Although you can do it with 10 or more players theoretically, with the 
more players you will have to prepare the greater amount of time. 
Practically speaking, the proper number of its players can be 3, 4, 5, 
or 6.  Each player is supposed to bring his/her musical instruments, 
some objects which makes sound, etc.
2) Useless paper etc. and coloured pens/pencils etc.
   In order to do Shogi Composition you have to prepare paper to write 
music down.  Of course you don't have to prepare 5-lined-music-paper 
because in Shogi Composition each player is allowed to write music down 
in his/her own way.  You can use drawing paper, useless calendars, 
useless posters and so on.
   You also have to prepare coloured pens/pencils etc.  Each player is 
supposed to choose one colour and use always the same colour.
   When you complete the composition, the paper will be the artistic 
picture as well as music score.
3) The process
   At first you have to decide who will start, and which way to go round 
the circle.  Then the first player starts to compose his/her part on his
/her own instrument(s).  When s/he completes his/her part, s/he writes 
it down on the paper in his/her own way with the coloured pen/pencil.  
Please notate it in any way as you will remember it later.  You may draw 
a picture how to play, you may explain by sentences, or whatever.  As 
soon as s/he writes it down, s/he hands the paper to the next player, 
starts to play his/her own composed part and continues it until his/her 
turn comes around again.
   Similarly the next player makes another part which goes well with the 
first part, writes it down in his/her own way next to the first part on 
the paper, hands the paper to his/her next player, and continues the 
part until his/her turn comes around again.
    Similarly keep this process.  Finally the last player writes his/her 
own part, s/he hands the paper to the first player.  Then the first 
player stops playing and listens to every sound, makes a new part which 
goes well with what other players are playing, writes it down on the 
paper, hands the paper to the next player, and continue it until his/her 
turn comes around again.
   Similarly continue this process.  Each player's notation does not 
have to be understandable for everyone.  If each player understands his/
her own notation and replays it later, any notation can be welcome.
   The length of each part does not have to be the same.  For example 
after the first player composes a 4-bar phrase of 4/4 meter, the second 
player can compose a 2-bar phrase of 7/8 or a 10-second-graphic-notated 
part.
   Continue this process without any break until you can not find any 
space to write down on the paper.  When the paper is full, composition 
is finished.  Don't stop the process until the paper is full.  If you 
can't help going to the toilet, wait for your turn to compose.  During 
your turn you may go to the toilet quickly.  For musical reason having a 
break during composition is absolutely bad.
4) Performance
   For the performance, at first the first player starts his/her first 
part and hands the paper to the next player.  Then the next player 
starts playing his/her first part and hands the paper to the next player.  
Similarly keep the process until everyone plays every part.
   Consult and decide how to finish the music before the performance. 
In order to play fluently, practise the piece you composed according to 
the Shogi Composition many times before the performance.
   For example it takes 2 hours for composition and only 6 minutes for
performance.
   You may photocopy the paper for each performers.
