If you blow across a glass bottle when it's a quarter full will the pitch be high or low?

I think the pitch would be lower because the sound is really low when it is empty.

Why does the pitch change when a bottle is hit on the outside as opposed to blowing over the top of it?
This must be because hitting the bottle makes it ring at it's natural frequency, which is determined by the glass envelope itself, whereas blowing across the top sets up a standing wave in the air inside the bottle. Thus they are two quite separate and different phenomena.
Can glass really break when you scream?
yes.if you make the right pitch
How is it possible to detect the filling of a bottle under a water tap by hearing the sound at a distance?
When the bottle is about to get filled full then pitch of sound would go higher. This because of sound coming from a closed organ pipe. With that change we can confirm the filling of the bottle
An example of is when a long high pitch causes a crystal glass to begin to vibrate and then break?
resonance
As you pour water into a glass you repeatedly tap the glass with a spoon as the tapped glass is being filled does the pitch of the sound increase or decrease?
when i tested it, i thought the pitch increased but it might just bemy hearing! My logic says, that the pitch should increase because as you pour, there is less glass available to resonate the sound.
How does the volume of the water in the glass bottles affect the pitch?
The pitch is governed by the length of the column of air in the bottle, so you can change that by adding or removing a liquid like water. Are you blowing across the top or striking the bottle?

What parts of the flute make the noise?
The headjoint itself, the embouchure hole specifically (the part you blow into) is where the sound is actually produced. The pitch is changed by the length of the flute changing, by pressing keys (much like when you blow across a soda bottle. the less liquid in the bottle, the lower the pitch)
How do pipes work?
The noise is simply made by air vibrating down tubes of different lengths and diameters. Blowing across the tops of the tubes sets up a vibration. The frequency (pitch/note) is determined by the physical dimensions of the tubes. If you blow across the top of an empty bottle you will hear a note. Try blowing across the top of a different sized bottle, or a bottle partly filled with water and you will get a different note. Pan pipes are constructed to take advantage of this phenomenon.
Glass full of water makes high pitch or low pitch?
Lower sound
Does the liquid in a glass effect the pitch of the note when a person rubs the rim of the glass?
Yes, the ringing is caused by vibrations. The pitch is determined by the frequency (measured in hertz) which is how fast the waves alternate up and down. The water blocks the vibrations making them need to travel less up and down the glass, which makes the pitch higher.
Has anyone broken a glass with a high enough pitch?
Yes. The pitch doesn't necessarily need to be that high, it just needs to be the resonant frequency of the glass, and very, very loud.

When you tap a glass with a little water in it It has a high pitch when you tap a glass with water filled to the top it has a low pitch why does this happen?
Glass has a natural frequency at which it vibrates, known as its resonant frequency. If you put energy into the substance at its resonant frequency, you will force it to vibrate or resonate (resonance is a forced vibration). So, tapping imparts energy to the glass molecules and causes them to resonate. This motion sets up a wave of vibration traveling through the glass. The vibrating glass causes air molecules to vibrate similarly. The vibrating air molecules are the sound wave that you hear (the frequency or pitch of the sound wave is the same as the resonant frequency of the glass). As the resonant wave moves through the glass, it moves the water molecules with it, creating a wave of water that you can see near the edge of the glass. The dragging water molecules effectively increase the mass (both the water and the glass molecules) and reduce the energy of the wave traveling through the glass. When the energy is reduced, so is the frequency of the wave in the glass, which is reflected in the pitch of the sound wave that you hear. In simpler terms, when you tap a glass with a lot of water in it, there are fewer vibrations because they have more trouble traveling through the higher mass. Thus, the lower pitch.
