Introduction

The three consideration, that affect the the delivery and outcomes of System 50:50

1. Number of players
2. Ratio of `freeplay` to `tacet` time on the chess clock faces.
3. Duration of the piece

Refer to the video, for more detail, a text summary will be uploaded here soon.

Ensemble Sound Mass

System 50:50 and Ensemble Sound Mass (ESM)

the formula is

[no of players] X [playing duration] = Ensemble Sound Mass
                 silent time

but also:

[Playing duration ÷ silent time] x no of players = Ensemble Sound Mass

Phil Morton suggests that ESM=3, or 4, is the starting point for any ensemble playing System 50:50 for the first time.

The ensemble, with its collective decision-making power, can flexibly change the ratio, the figures, and the ESM when it deems itself ready to do so.

Phil Morton suggests that ESM=3, or four or less, is the starting point for any ensemble playing System 50:50 on Zoom. The experience is that Zoom cannot manage higher sound mass values, and sound fidelity issues will arise.
