GLASS HARMONICA

The glass harmonica was once a popular musical instrument. Among the great composers who wrote music especially for it were Mozart and Bethoven. The instrument consists of glass containers with them. The water level has to be adjusted carefully to make each glass sound a particular musical note when struck.



*For making a glass harmonica, you need eight different size glasses, one pencil and one water jug. 


*Strike some old glasses with a pencil. Select glasses that give a clear tone when struck.

*The glass harmonics covers a musical note called an octave. The eight tones made by glasses form the scale do-re-mi-fa-sol-la-ti-do. To tune the glasses, first fill the largest one with the water. This is glass number 1. Strike the glass and call the tone you hear do.

*Sing the next note of the scale (re) and tune the next glass to this tone by adding water, a little at a time.

EIGHT DIFFERENT GLASSES WITH DIFFERENT AMOUNT OF WATER
*Continue in this way until you have eight glasses tuned to the notes of the scale. You will probably need to use smaller glasses to get the higher notes of the scale. If you are unable to sing the scale, tune the glasses to tone on a piano or organ.

*Now see if you can tap out a tune on the glasses. If you find this difficult, try tapping the glasses in the following order: 5-3-1-3-5-8. Continue the tune and enjoy the music!
