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.”

The search for low sounds in the universe of found instruments is always a challenge.    It usually means finding something big, like long lengths of PVC pipes, which can be difficult for touring. For bottle sounds, the depth and low range of the perfect gallon jug is worth the trouble of collecting, cleaning, and carefully transporting.

The range of a glass cider jug extends below a wine bottle or an old vinegar jug. It takes an enormous amount of air to produce a good clear sound. And to get enough air, one needs to take deep noisy breaths. But this is actually a bonus, because the sound of the in-breath just before the articulated note, can form part of the music. The in-breaths are quite audible, especially when the mics are close and hot. So using this sound will be an interesting way of allowing a natural percussive line to be heard while producing the pitched sounds from tuned blown jugs. The real breath sounds produce a sense of necessity and energy in the music.  This technique is used in the song “Why Don’t We” from the album “Whisper in My Ear”.
