You can also compare the note frequency with notes sounded on a piano or keyboard. Again, you can use the reading from the chromatic tuner to determine the note the glass makes when rubbing it with your finger or hitting it with the metal spoon.Do you get the same note again or is it different? Take the metal spoon again and very gently tap the glass on the side.Does the water surface stay calm or do you see any disturbances? Watch the water surface in the glass carefully while you are generating the sound.What note does the glass make now? Is it a higher or lower pitch? Now fill one-third of the glass with water and repeat the procedure.What note did the glass generate? Can you sing the same note? If you are using a chromatic tuner, use it to determine the note the glass makes when rubbing it with your finger or hitting it with the metal spoon.Does this generate a different sound or note compared to when you used your finger to make the glass sing? Take a metal spoon and very gently tap the glass on the side.Now make the glass sing again and stop rubbing your finger along the rim but this time leave your finger on the rim on the glass.Does the glass continue to sing or does it stop? While you hear the glass sing, stop rubbing your finger along the rim and take it away from the glass.Does it feel different than with a dry finger? How much resistance do you feel this time? Does the glass start to sing? Tip: If you hear no sound, try changing the speed and applying more or less pressure to the rim. Rub your finger around the rim of the glass again while pressing down gently.Wet the index finger of your dominant hand with water.Does your finger stick to the glass or is it gliding smoothly along the rim? Do you hear a sound? Rub your dry finger around the rim of the glass while pressing down gently.Hold down the base of the glass with your non-dominant hand.Take an empty wine glass and put it in front of you on the table.Wash your hands with dish soap and rinse your hands thoroughly.Carefully gather your wine glass(es) and your measuring cup, as well as some water.Find a working area that can tolerate some water spills.Piano or keyboard for comparing notes (optional). #ABOVE THE RIM STICK EM UP SONG FREE#Chromatic tuner (optional, available as free phone app).Wine glasses and permission to use them carefully (optional: different size and shapes).Now let's make some music and you can play your very own wine glass instrument. The resonant frequency of wine glasses is typically within the range of human hearing (20-20,000 Hz), and this is why you hear the resulting resonant vibration as a tone. There is a particular frequency, called the resonant frequency, at which the sides of the glass will vibrate most easily. The frequency specifies the rate at which a vibration occurs and is usually measured per second or Hertz (Hz). The sides of the glass transmit the vibration to the surrounding air, creating a sound wave with a specific frequency. When the pressure and amount of moisture are just right, this so-called stick-slip motion (the slight friction between your finger and the rim of the glass) will cause vibrations in the sides of the glass. The water on your finger, however, will allow your finger to slip, as it forms a cushion that reduces friction. When you rub your moistened finger along the rim of the glass, your finger will stick to the glass as it encounters resistance, or friction, when it moves over the glass surface. Both of these instruments are based on the principle of generating musical tones by means of friction. About 10 years later, Benjamin Franklin-one of the founding fathers of the United States-invented a mechanical version of the glass harp, called the glass harmonica. The first musical instrument made of upright wine glasses was called the glass harp and was invented around 1750. Glasses have been used for making music since the Middle Ages. #ABOVE THE RIM STICK EM UP SONG HOW TO#But did you know that you can make wine glasses sing? Perhaps you have done this many times before, but have you ever wondered why the wine glass makes this sound? Do this activity, and you will not only make wine glasses sing, but you will also learn how to generate different notes you might even get inspired to play a little song. #ABOVE THE RIM STICK EM UP SONG FULL#The table is full of delicious food-a big feast-and there might even be some fancy dishes and glassware on the table to make the celebration even more special. Thanksgiving can be a wonderful time of year, with friends and family getting together. ![]()
