how to make that beautiful sound on a bottle

The Minden Duo uses glass bottles for many of their compositions, all sizes and shapes of bottles can be used each producing a unique timbre.  Carla plays most of the bass jugs because of her training as a horn player:
“I find the best one gallon cider jugs in Canada are supplied by “Triple Jim’s”. The cider is a bit on the sweet side, but the bottle itself has the best taper in the neck, and the opening at the top is not too wide. This makes for a better, more focused tone. I find some cider jugs have an excessively wide mouth and neck making them very difficult to create a clean sound and requiring huge amounts of air, only to produce an overly diffused tone. Exceptional lung power is already a basic requirement to play even the most optimum one gallon jug if you want to have even the slightest amount of sustain. And I don’t mean that one needs to emulate the sustain of a piano. We want a bottle to sound like a bottle. But do take care not to make life overly difficult by playing an inferior jug.”
