System 5050 and the density index

System 5050 and the density index

Phil Morton's observations and speculations from research work with system 5050 using the `trio`

The trio played short pieces 4-6 minutes long, which will produce a musical experience whose soundings could be described as `thin`

The trio also used two ratio settings on the manual chess clocks, 50:50 and 33:66 - refer to the video for details.

The observations and speculations from his listening body are

  1. The density index exposes two different ways of playing, the placement of sound that is of itself and the collaborations of people and sounds that create a narrative in a timeline (temporal?)
  2. The density index offers a simple and structural method to take a group of players and move through the different densities and experience different [help me out here?] sonic relationships and characteristics.
  3. This is can be used with a group of any size but Mr. Morton speculates this is a very significant and helpful tool for improvisers who are interested an `orchestral sound` experienced when the musicians' count is large, PM speculates over 8 - nay more than 12.
  4. The sample count is small - one session.
  5. These findings are linked to Mr. Morton's hypothesis, that `System 5050` works differently in different settings, so its dynamic, has depth. System 5050 is not singular or flat.
  6. He commends these finding to the house.

The Density index - the spreadsheets

This video playlist of three videos explores, tries to explain, and show the `density index` concept and realise in a spreadsheet format.

The proposition is that this concept can be explored and deployed by an ensemble of any size and a wide range of results may arise. To be researched.

It is assumed you have:

The playlist is

  1. A one-minute introduction - this can be skipped if you have viewed it before
  2. The second video introduces the research and the `density index`- came to light.
    1. The second video title is `System 5050, mathematics and the density index concept
    2. Skip this video if you have seen this before.
  3. The third video is the target of this presentation. It takes the density index and the three variables, the number of players, the duration of the piece and the DI index and shows us the `clock settings` and timing (tacet/free play) for any combination of the aforementioned variable. Very clever indeed if you ask me!
  4. The consequences of these findings are to be explored.

Here is a link to the source spreadsheets, with view-only rights URL LINK


Notes and troubleshooting the video

  1. The use of the phrase 5050, could be confusing, Mr. Morton thinks 50:50 equates to 50% - 50% as in, 50% free play, 50% silence. `50:50` was the starting point for this project but as you may know realise, the `percentages` or the ratio's can be changed. Mr Morton suggests 50%:50% is a ratio of 1:1
  2. NOTE - For your information, and useful to know on the topic of the DI Index
    1. The DI index for a piece using a ratio of 1:1 or 50%:50% is always the same as the number of players, for example, 8 players playing 50:50 or a ratio of 1:1 will always have a DI value of 8,  refer to spreadsheets for the evidence.
  3. The videos, the first or second drafts, were recorded on the fly, without any notes, so please cut me some slack!
