This scheme may be performed by any combination of two to four instruments. Each player chooses a different side of the square. He then improvises on the given pitches from left to right and on each successive staff as is conventional staff arrangements. When a player encounters intersecting staves, he raises all pitches within that intersection one semitone. No clefs are indicated. Octave transfers are permissible when necessary.

Pitches with a bisecting vertical line () signal a regularly pulsating flutter tounge, tremolo, trill (to an adjacent pitch) or roll. Pitches with adjacent vertical lines signal an irregularly pulsating flutter tongue, tremolo, trill or foil. Pitches appearing simultaneously may be played as double stops or as rapid tremolos. The relative duration and intensity of pitches is determined by their size: large notes are loud and long, small notes are soft and short.

This relationship may at times be reversed, depending on the musical situation of the moment.

Generally, the closer the proximity of one note to another, the quicker the rhythmic design.

Each player performs ten successive staves. Blank areas are silent spans of time. Areas on staves where no pitches appear may be silent, or they may be used for free improvisation. An overall time span of twenty seconds per staff controls the length of the improvisation. Each player performs his staves according to the overall tempo scheme indicated at the top of his side of the square. For instance, a tempo scheme of "Fast-Slow-Moderate" might be performed as follows: ten seconds for the first two staves 150 seconds for the middle si staves and forty seconds for the remaining two staves.

Types of timbre, attack, release etc. are left to the improviser.

Percussionists are free to assign a variety of instruments and/or timbres to the lines and spaces of the staves. If the combination includes idiophones, it is suggested that notes above and below the staff be played by these instruments.
