On a syphon type, the diaphragm will scream if perforated or cracked. Depending on which system you have fitted, this could be anything from the ball valve to the flap valve and all points between.
Below are instructions to change something completely. If you recognise what system the contributor is referring to all is well. For the rest of us it makes little sense.
Explanation of a repair to an unspecified flush system
I don't know why but follow these instructions EXACTLY to fix it.
Turn off the water supply to the toilet. Follow the hose attached to the bottom of the toilet tank to the cut-off valve. Turn this valve clockwise to turn off the water. Empty the tank by flushing the toilet, then dry out the toilet tank using old towels or a sponge. Place a bucket under the toilet tank to catch any water that is still in the tank.
Unscrew the nut holding the hose to the bottom of the tank with vice grips or channel locks.
Remove the nut screwed on to the toilet pump. This is under the toilet tank. After you loosen this nut, you may need to hold the toilet pump with one hand while removing the nut with the other because the toilet pump may turn with the nut.
Remove the clip attached to the refill tube from the overflow pipe. Remove the toilet pump from the toilet tank.
Attach the refill tube that came with your replacement toilet pump to the new toilet pump. Slide one end of the refill tube over the nipple on the toilet pump to cover the nipple completely. Attach the angle adapter to the other end of the refill tube.
Place one of the shank washers that came with your replacement toilet pump on the threaded shank of the new toilet pump. Place the threaded shank into the hole in the bottom of the toilet tank.
Fit the other shank washer over the threaded shank and push the washer firmly against the toilet tank.
Replace the nut on the threaded shank of the toilet pump and tighten fully.
Clip the refill tube to the overflow pipe using the angle attachment provided.
Screw the water supply hose tightly onto the threaded shank. Turn the water supply back on and check for leaks. If water leaks from around the new toilet pump, check to make sure both shank washers are firmly in place and tighten both nuts fully.
A toilet might make a burping sound when flushing due to air that was trapped in the pipe. Sometimes giving the toilet a quick plunge will prevent this.
I had the same issue with my Cherokee Sport 4.0 until I had the heater core flushed. After a couple trips once flushed, high pitched sound discipated.
In order for water to flow down a pipe, there must be a vent to allow the air to escape. Above a toilet, on the roof, there is usually a pipe or a vent hood, which is connected to the drain pipe. When the toilet is flushed, the sound of water draining can be heard issuing from this vent. In addition to the above answer, the air rushing through the water may be the cause of the gurgling sound, which is the air escaping through the vent to prevent the build up of air pressure inside your water system.
The high-pitched sounds you hear are the upper harmonics of water hammer, and flushing the toilet without adding enough toilet paper to absorb the squealing sound. Without toilet paper in the pipes, they will vibrate and possibly crack the solder in the pipe joints. If you really want to do yourself a favor, wrap ALL the water pipe joints in high density foam rubber (HDFR - plumbing supply shops provide these in assorted colors to mark off different areas - kitchen, bathroom, garage, etc.).
A lower-pitched sound has a higher frequency than a high-pitched sound.

A defective vacuum line can cause a whistling sound when the vehicle is accelerating. A loose belt can also create a high pitched whistle sound.
There is no musical note that is the sound of a flushing toilet. It's only a sound effect, it doesn't have any tone to it.
