The electronic exists as a fixed playback track or as a maxpatch for triggering the individual samples via a controller (eg midi pedal).
Player: 60 litres of air per minute (serious sport!)
1 litre air = 1 gram, CO2 in exhalation: 4 %
60 l/min = 360 l for the piece (6 min) = 360g air, 4 % is 14,4g CO2
2 Speakers per 500 Watt, 0,1 hours = 100Wh = 100g CO2
Laptop: 25W, 0,1 hours = 2,5 Wh = 2,5g CO2
Total: 14,4g + 100g + 2,5g = 116,9g CO2
This is the amount of CO2 for every performance. No rehearsals included in this calculation. Please note: The less rehearsals, the better for the enviroment!
Matthias Kronsteiner, Fagott
