This is why the empty bottle should have produced a sound wave with a lower frequency than the others and the bottle that was nearly full (three quarters full) should have made the highest pitch.
A bottle is actually what is called a "closed-end air column." Clarinets and some organ pipes are examples of musical instruments that work in the same way.
Fill this zelf xtc pillen maken bottle with water up to the mark you just made.
These bottles will function as closed-end air columns, which are basically tubes that are open at one end but closed (or covered) at the other.Full Definitions of high-pitched 1 adj used of sounds and voices; high in pitch or frequency.Have you ever blown across a bottle's top and made a pleasant, resonant sound?String instruments can be played in many ways, and come in many variations.What about the height of the bottle or how full with water it is (or the level of remaining air)?Extra: Try repeating this activity but use bottles that are different shapes and sizes.You are here: Home experiments / Pop Bottle Music, making sounds by blowing air and tapping the glass.Synonyms: high adenoidal, nasal, pinched sounding as if the nose were pinched altissimo very high alto (of a musical instrument) second highest member of a group alto, countertenor of or being the highest male voice; having a range above that of tenor falsetto artificially high;.How do musical instruments make the sounds that they do?Did the bottle that was filled three quarters full with water make the highest pitch?How does the note this bottle makes compare with the one made by the half-full bottle?
2, fill a third bottle half full with water.
String instruments must be tuned perfectly by tightening or loosening their strings.
In this science activity you will use bottles to investigate how the length of a closed-end air column affects the pitch of the note that it makes.
In other words, the pitch depends on how much water has filled up the bottle and how much empty space remains.
Some of the simpler instruments are the string instruments.
Fill one bottle full with water and leave a second bottle empty.

This means that the half-full bottle should have made a note one octave higher than the.All sound is made by vibrations that travel through the air.What do you notice?String instruments make sound with vibrating strings, and the pitch is modified by the thickness, tension, and length of the string.Leave the third bottle empty.Experiment Materials 8 glass Orange Crush bottles (all of the bottles must be the same!).Materials, three identical narrow-neck bottles (They can be glass or plastic.).Denver Office 4400 South Federal Blvd, englewood, Colorado 80110, scroll to top).Instruments like the zither, harp, and piano have sets of parallel strings, one for each note, that can be sounded individually, or together to make chords.Electric guitars use magnetic pickups to convert vibration to an electric signal.(For more on the mathematics behind this, see the "More to explore" section.) Similarly, the three-quarter-full bottle should have produced a frequency that was twice that of the half-full bottle.

Then blow across the top of the bottle that is three quarters full.
Touch your lower lip to the edge of the bottle, pursing your upper lip and blowing gently over the opening.
