I will try to explain how the drone grid works. It is very important to know some things about the drone reads, and mainly uh how, when we are trying to to play back pipe, we need to know we need to know, and we must to understand how the bagpipes works well, one of the most important and Main things are the drone rates tuning drones is a very, 非常, not difficult, but not easy work, but well, if we understand the function of these pieces called ritz in that case drone rates, because the chanter have another rate and we call we named chanterite well. This is a column mg designed by the great musician piper rory grozart. 好, we can see here the body of our drone rate is screw and a tongue and a bridle rubber, usually rubber, bridle. 好, the rubber bridle uh works lengthening if we go upstairs the tongue and shortening if we go down the base or or the seat, the the the bottom part of the drone drone rate. 好, this part, if we release too much tongue, we will need a lot of extra air to make a good sound to get and have a good sound. Then we must to look for the right point where our drones requires the exact or more or less, 大约. The the best point to get the drone reads: air efficiency. We will not spend more air than necessary well. This crew is also a very important part because if we close uh in the clockwise sense sense or way, we will short the shortening.
We are shortening the inner chamber and then the pitch will be sharp sharper in the opposite case anti clockwise. We will have more inner chamber released and then the sound of the drone read will be lower. I think this is more or less and very, very simplify the function and working of the drone grids. The pitch is very important when we put the chanter um we have to harmonize or to put in the same level or to tune the chanter with drones, but well, this is other other thing over there. Other point we need to know is the bass drum. This is the bass. Drone is longer than the tenor drones grids, drone grids. This is the base the base drone rate work more or less 140 vibrate. When the when the air excuse me, i forget when the air crawls through our drone raid in the case of the base drone the tongue vibrates more or less 140 times per second, is very, very high amount of times and in the chain of drones. The vibration the tongue will vibrate 440 times per second, because our base drone is two octaves below the chanter and the channels are shortening shorts. The tenor are only one octave below our chant.
